what does freezing do to a rock?

Rocks are already frozen. Unless, of course, they are molten.\n\nBut that's probably not what you meant. If a rock is pourous or has cracks, water can enter and fill the cavities. When the water freezes, it will expand and could crack the rock.

With modern technology, it isn't possible.  When the water in our bodies freezes, it forms ice crystals that puncture cell membranes.  If the body were to be thawed, the insides would be mush.  However, many people still put themselves into deep freeze in hopes that we will be able to counteract the negative effects of deep freeze.

Yes.  Salt water freezes at a lower tempurature than fresh water. \n\nThat is why we use salt to melt ice on sidewalks in the winter.

Interesting theory, however water expands when it freezes.  It has no problem melting under pressure.

Air temperature may be several degrees warmer than ice surface temperature. Light, including infrared or warmth, is reflected from white surfaces.\n\nThe surface of the ice will melt, slowly, during the day, but it will freeze again over night. That's one of the reasons why a snow field slowly turns into ice.

The snow holds pockets of air which act as insulation.Because they are low and round the heat circulates lower in the shelter.The heat is provided by the human body and can be regulated by the individual possessing that body.The igloo also shelters from the elements such as wind chill

when you pour water on the ice, the ice has layer of water around it, but its still really cold. when the new water stays next to it, the ice cube freezes the water around it, if two ice cubes are touching, they will freeze the water between them and stick to eachother

Flyboy is correct. When the water freezes it must loose heat. Since it is in direct contact with the orange it conducts the heat to the orange, heating the orange. Thus they are saved!\n\nA problem arises when they thaw. Thawing involves the ice needing heat. It takes some from air, but because of direct contact with the orange, it will take heat from the orange and the orange will freeze. So the orange must be sprayed until it (the ice) thaws so the heat to thaw comes from the water, not the orange.\n\nGet an "A".

Some plants are considered 'hardy', which means that they can resist a winter freeze very well.\nThe root of the plant can survive underground and bring the plant back to life in the spring.\n\nOther plants aren't so hardy, and if you don't cover them during a freeze to protect from the cold, the plant will freeze from root to tip and not be able to rejuevenate it.\n\nHope this helps.

Error and Deposition by Gravity\n\nGravity is the force of attraction that exists between all objects. Because Earth has great mass, other objects are attracted to Earth. This makes gravity a force of erosion and deposition. Gravity causes loose materials to move down a slope. When gravity alone causes materials to move downslope, this type of erosion is called mass movement. \n\nA slump is a mass movement that happens when loose materials of rock layers slip down a slope. In a slump, strong rock or sediment lies over weaker materials. \n\nCreep gets its name from the way sediments slowly inch their way down a hill. \n\n"Falling Rock" sign warn of another type of mass movement called a rockslide. Rockslides happen when large blocks of rock break loose from a steep slope and start tumbling. As they fall, these rocks crash into other rocks and knock them loose. \n\nMudflows usually occur in relatively dry areas where weathering accumulates thick layers of dry sediments. When heavy rains fall in these areas, water mixes with sediments and forms a thick pasty substance. Gravity causes this mass to slide downhill\n\nGlaciers\n\nGlaciers are agents of erosion. When snow doesn’t melt, it begins piling up. The weight of the snow becomes great enough to compress its bottom layers into ice. The ice on the bottom partially melts and becomes putty-like. The whole mass begins to slide on this putty-like layer, and it moves downhill. \n\nContinental glaciers are huge masses of ice and when snow  once covered up to 28 percent of Earth they were called ice ages. Today glaciers cover only 10 percent of Earth, mostly near the poles in Antarctica and Greenland. \n\nValley glaciers occur even in high mountains where the average temperature is low enough to prevent snow from melting during the summer. \n\nGlacial Erosion\n\nAs they move over land, glaciers are like bulldozers, pushing loose materials out of their path. Eroded sediments get pushed in front of a glacier, carried underneath it and piled up along its sides. When glacial ice melts, water flows into cracks in rock, refreezes in these cracks, expands and fractures the rock into pieces. These rock pieces are then lifted out by the glacial ice sheet. This process, called plucking, results in boulders, gravel and sand being added to the bottom and sides of a glacier. As a glacier movers forward, plucked rock fragments and sand at its base scrape the soil and bedrock, eroding even more material than ice alone could. When bedrock is gouged deeply by dragged rock fragments, these marks called grooves, are deep, long, parallel scars on rock. Less-deep marks are called striations.\n\nGlacial Depostion\n\nWhen glaciers begin to melt, they no longer have enough energy to carry much sediment. The sediment drops or is deposited on the land. This mixture of different sized sediments is called till. When melting of a glacier exceeds snow accumulation, the glacier retreats or starts to melt. Material deposited by the melting water from a glacier is called outwash.\n\nWind\n\nWind erosion occurs when wind picks up loose material and transports it to other places. Wind erodes Earth’s surface by deflation and abrasion. When wind erodes by deflation, it blows across loose sediment, removing small particles such as clay, silt, and sand, leaving coarse material behind. When these windblown sediments strike rock, they erode by abrasion.\n\nSand storms occur when wind-blown sand grains form a low cloud, just above the ground. Dust storms occur when wind carried dry soil over hundreds of miles. \n\nTo reduce wind erosion, windbreaks are planted to catch blowing soil. Along many steep slopes, seacoasts and deserts, people plant vegetation to hold the soil with plant roots. Sediments blow by soil eventually deposited and develop into either a loess or a dune. Fine-grained sediments of soil deposited on hilltops and in valleys are loess. Sand mounded in front of an obstacle, such as a rock, produces

The chemical reaction from adding\nsalt lowers the temperature in which water freezes.\n\nThat is why they throw in onto the roads in areas of winter freezing.

So anti-freeze and salt causes a freezing point depression in the water which means as you add solvent such as salt the freezing point is lowered (hence when you add salt to your windshield the ice melts).  There is a simple mathematic equation that will relate the change of Temp freezing to the amout of solvent added.  (ΔTf = Kfcm).  Kf is the freezing point constant of the solvent and cm is the molal concentration of the solvent. So as you can see from the equation the ΔTf will be greater as you increase cm so the effects of adding a solvent will depend on how much solvent you add.  \n\nSo a simple experiment would be to add increasing amounts of salt and antifreeze to constant volumes of water and determine the freezing temperatures of each one.  You should also want to calculate the molal concentration of each one and try to determine before hand what the freezing points should be (hypothesis).

The 'science guru' is right, but I'll chime in to try and help you wrap your mind around it. \nThe slower magma cools the bigger the crystals in it get. The deeper the magma is in the earth the more it is insulated (like a pizza in one of those pizza delivery bags) and so it cools lots slower the deeper it is.\nThe faster the magma cools the smaller the crystals in it. Since the earth insulates the magma it has to get closer to the surface before it can cool fast enough to have small crystals.\nIf you have two different sizes of crystals then you must have two different rates of cooling.\nThe crystals that can form at higher temps start forming first, of course, and then, when the magma gets pushed up nearer the surface the rest of the material cools quickly into small crystals that surround the larger ones.\nDoes that help?

Ice is water but in a solid form.  Water consists of H2O.  The bond between the H-O is a special one because of the difference of electronegativity is great enough but not enough to affect other water molecules and form a weak intermolecular H-O lattice, but not enough to form ionic bonds out of these.  So, this H-O lattice causes water to have properties such as this where at around 0 degrees Centigrade, it intermolecular forces and the lack of vibrational forces for the molecules cause them to form a solidified network latice of water molecules (ICE).  When rock salt is introduced, this lattice network is broken because salt (ionic compound) dissociates upon the impact of water.  Water is highly polar and the salt has a positive and negative charged ions associated to them.  These ions disrupt the network of hydrogen bonding that has faithfully held the water molecules together, thus changing the exterior requirments to solidify them.  Either pressure has to increase or temperature has to decrease in order to have intermolecular forces that are great enough to cause rigidity.  And there goes your reason why salt melts ice and the need for salt to melt ice from time to time.

Weathering is the process that breaks down rocks into smaller and smaller fragments. Over millions of years, the process of weathering helped change Earth’s surface. Weathering blurs the writing on tombstones and slowly breaks down statues. Weathering can also cause potholes in streets. The two types of weathering are mechanical and chemical. Although mechanical and chemical weathering are discussed separately, the two processes work together to break down rock.\n\nMechanical Weathering\n\nMechanical weathering breaks apart rocks without changing their chemical composition. Each fragment and particle weathered away by a mechanical process retains the same characteristics as the original rock. Mechanical weathering can be caused by growing plants, expanding ice, growing crystals, lightning, and expansion and contraction with heating and cooling. These physical processes create enough force to break rocks into smaller pieces.\n\nChemical Weathering\n\nThe second type of weathering occurs when water, air, and other substances react with the minerals in rocks. This type of weathering is called chemical weathering because the chemical composition of the rock changes.

Dig as deep as you can, unless that would strain your energy. Snow/ice are okay protection (Eskimos survive in igloos), but if the ground isn't frozen, I would try digging because it can be warmer. Ice can't get any colder than 32F, so if the temp outside is below freezing, the ice will be warmer.
