Increasing this causes rocks to breakdown faster?

does concentration fit there.\ni dont see anything else and dont understand the clue

Fossil bones and shells have turned into rocks.  That's why they're heavy.

chemical erosion (dissolving elements from the rocks) deepen the cracks between the rocks creating the pavement effect

x is greater than y. when the rock is on the boat, it displaced water equal to its weight. when its in the water, it displaces water equal to its volume. the rock's density is greater than that of water. so more weight than volume equals more water displaced while its on the boat which means the level is higher.

Through the processes of weathering, erosion, deposition, sedimentation, cementation, & lithification an igneous rock can become sedimentary.\n\nIgneous rock can be weathered by one of two processes. The first is mechanical weathering. This would include things like the freeze/thaw cycles. Water entering into tiny cracks in rock will freeze causing the crack to expand. There is a larger gap left when the ice melts. Some types of igneous rock will also exfoliate. As they emerge to the surface through uplifting, they will expand (due to less pressure). Sheets of rock will literally peel off from the rock's surface and fall at the base of the rock.\n\nThe other is chemical weathering. This is usually b/c of water's interaction w/ the minerals in the rock. One type of mineral will break down into another more stable one.\n\nThis weathered rock can erode & be transported elsewhere where it is deposited as sediment.\n\nMany layers of sediment may be placed down. Pressure from the layers above cause the water & air in the sediment layers below to be squeezed out.\n\nPressure from above, along w/ dissolved minerals left behind from the water, can cause lithification & cementation to occur.\n\nThese processes take quite some time to occur.

In general, the more clay in the soil, the higher the cation exchange capacity, the greater the rates of expansion (i.e. greater rates of saturation).\n\nMontmorillonite would expand quikcer because it has the highest cation exchange capacity of all the 2:1 lattice clays.  This higher cation exchange capacity allows for the clay minerals to bond quickly with water or with base cations present, therefore expanding quicker than vermiculite which has a lower cation exchange capacity. \n\nHowever, a vermiculite that is not saturated with base cations will expand quicker than a montmorillonite that is saturated with base cations.  If neither is saturated, the montmorillonite will expand quicker because of its greater cation exchange capacity.\n\nMontmorillonite clays mixed in with soil will be far more fertile than vermiculite mixed in with the soil.  However humus has an even higher cation exchange capacity than both montmorillonite and vermiculite.

Either drop the temperature (remove the enthalpic - heat - energy) or increase the pressure (the less space it has to move freely the closer to solid it becomes) or both

Generally, they're formed by freezing and erosion. Essentially what happens is that water gets into the cracks of larger rocks and then freezes and expands, causing pieces to fall off. Sometimes these smaller rocks end up in streams or rivers where they are carried by the current and rolled along the bottom, smoothing them out. over time, they get smaller and smoother becoming what we know as pebbles.

Lacking more detail - my suspicion is that the release of H2 will cause the amount of aluminium to be to high...\n\n-dh

By unit volume, probably dry cement is heavier. Why? Because rocks are heavier than water.

a sudden break in the rocks of Earth because of being stressed .. at depths range from the earth surface to 720 km .. this releases kinetic energy which spreads in every direction as seismic waves wich cause the vibration of the molecules of the meduims they move through !!!

because weathering breaks down rocks     in time it will bring down mountains      weatheing makes streams    plants use stream water    weathering makes rivers   and if not makes them it makes them bigger wich makes water more conveinient   and in old times rivers were the main and/or only way for travel to great distances and trade.    and thats just a tiny little detail me brother 11 yr old brother just thought of

Depends on the kind of rock.  Some of them probably won't dissolve easily -- you'd have to pulverize them first.

First let me say that this is a guess--- Because the earth is getting hit with metors I think the volume will go up-- against this argument is the idea that as it cools it will shrink.  My guess is that the increase will more than offset the cooling factor further if the exterior is actually warming it might expand while the core cools and shrinks.  I wonder if that will cause voids and big sink holes.

The rock cycle is the continuous movement of rock from one type to another. These processes occur over long amounts of time. All rock started out as igneous. From there, rock can then become sedimentary, metamorphic, or igneous again in any order.\n\nIgneous --> Sedimentary:\nIgneous rocks break down through weathering processes. The broken down rock becomes sediments which are deposited by wind or water. Layers of sediment build up on top of each other. Pressure, along with dissolved minerals, help to "glue" the rock together.\n\nSedimentary --> Metamorphic ("change form"):\nIf the pressure is great & enough heat is applied, metamorphism can occur. This causes the rock to become more compact & dense. If too much heat is applied then the rock will melt. See below.\n\nMetamorphic --> Igneous:\nIf heat is applied to the point of melting, the rock will go though the igneous phase again.\n\n:)
