what are the pysical features of the earth that make it ideal habitat to human being?
396636
water, the oxygen and the abundant food. these are basic things that human being need on the earth.so all these can be found on the earth..water from rivers.oxygen from the air and food from fruit/trees, animals etc etc.

Human geography deals with people and how they interact with their surrounding environment.

Humans will probably live on Mars at some point, though it would probably be only temporary.  Now let's look at the problems.\nThe biggest problem would be making Mars a suitable environment for human life.  Terraforming the planet to give it a similar atmosphere as Earth would take thousands of years, if not longer.  The other option would be to build colonies.  And even then there's the question of what to do about gravity.  Because the gravity on Mars is less than that of Earth humans would have a difficult time maintaining muscle mass and bone density.  So, some sort of solution would need to be found.\nNext, let's face it, Mars is terribly far away and has little to offer, except maybe some frozen water.  And being so far away from Earth would probably be very problematic.  It is much more likely that in the future, if humans are to live in space, they'll live in self-sustained space colonies orbiting the Earth.

The earth is pretty resilient. Humans will cause great hardships on themselves, maybe even destroy themselves, before they change their ways. Whatever the outcome of human life, the earth will recover. We will colonize other planets if we survive ourselves.

the Earth 3rd planet from the sun; the only planet were life exists; the Earth moves around the sun.\n\nto know more about the earth or the astronomy and space contact me :)

Most of the earth Surface is Covered with water, but that's only a small fraction of the planet itself. The Earth is made up mostly of silicate and magezeuim compunds and an iron core.

The earths atmosphere\n\n\nMy first thought was not formal. What I thought when I read your question is that nothing is between heaven and earth that "the heavens" come down and touch the earth.

Ocean\n\nB/c we need to gain a greater understanding of where we live now (Earth), then prematurly pushing our limits in space. Space will come in time, but Earth cannot wait forever to be healed from our destruction.

Dude - its your homework - my help to you is stop screwing around and write it.  However - I would suggest you check out links here http://www.ask.com/web?q=the+earth+is+beautiful&qsrc=145&o=10429&l=dir to give you ideas.\n\nGood Luck!!!

Soil is the collection of natural bodies that form in earthy material on the land surface. The term is popularly applied to the material on the surface of the earth's moon and Mars, a usage acceptable within a portion of the scientific community.\n\nSoil consists of mineral and organic matter, as well as living organisms. Soil, comprising the pedosphere, is positioned at the interface of the lithosphere with the biosphere, atmosphere, and hydrosphere. Pedogenesis produces soil from geologic materials such as granite, limestone, glacial drift, loess and alluvium through a combination of climatic and biogeochemical processes.\n\nSoil is among our most important natural resources because of its position in the landscape and its dynamic, physical, chemical, and biologic functions. Indeed, engineers, agronomists, chemists, geologists, geographers, biologists, microbiologists, sylviculturists, sanitarians, archaeologists, and specialists in regional planning, all depend on, and contribute to, knowledge of soils. While the general concept of soil is well established, the definition of soil varies, according to the perspective of the discipline or occupation using soil as a resource.\n\nThe understanding of soil is incomplete. Despite the duration of mankind's dependence on and curiosity about soil, exploring the diversity and dynamic of this resource continues to yield fresh discoveries and insights. New avenues of soil research are compelled by our need to understand soil in the context of climate change , greenhouse gases , and carbon sequestration.  Our interest in maintaining the planet's biodiversity and in exploring past cultures has also stimulated renewed interest in achieving a more refined understanding of soil.\n\nclick here:http://en.wikipedia.org/wiki/Soil#Soil_classification\n\n\nif you mean Earth,click here:http://en.wikipedia.org/wiki/Earth

The earth has four layers...\n\nTheCrust, Upper mantle, Lower Mantle and the Core refer to <http://volcano.und.edu/vwdocs/vwlessons/lessons/Earths_layers/Earths_layers1.html>\n\nThe Crust has many hollow parts like caves. Caves connected to the ocean and some undergorund river, near an instict volcano is posible of supporting life.\n\nHumans can live there but not making civilization. Just hiding from dangers on the surface such as crusaders, barbarians, dinasours, wild animals...at the present these caverns is used for safety hiding places from war, nuclear attack and for the one of the most dangerous speicies on earth and that is the Humosapiens.....

The law of human geography is that people can adapt to any environment.

Depends.  We can live on other planets and other places of the universe if we adapt.  (i.e. we could build a moon base and live inside the moon base with air and sustaince)\n\nThis would be considered the "artificial" way of living on another planet.\n\nBut assuming you question was as to naturally living on a planet; what deters us from being able to live on most other planets "naturally" is because they don't satisfy living conditions needed for humans such as:\n\nhabitable atmosphere\nsustaining gravity level\nlivable temperatures and weather \neasy geology, soil compensation\nsources of sustenance such as water/vegetation\nmagnetic field, dynamo\n\nOkay each explained.  As we live on earth with certain conditions any extreme can cause complications.\n\nWe need habitable atmosphere to breathe.  Also it needs to be existing at some level to block out radiation from intense solar rays (if a star exists there).\n\nGravity level needs to be subjected to our existing body shape and form.  If gravity was too intense our body would pull down that would form an evolution of us to become more flattened and shorter.  We may adapt but it would definitely make it hurt while there.  Atrophy is a key term here!  Same goes for other way.  We would end up being bouncing up and down if we were on a low gravity area.\n\nHaving temperatures in sync to our bodies ability to adapt is important.  If we are able to sustain handling colder weather by warming up with jackets and heat sources maybe.  But let's say it's a place of 500 degrees below zero.  Then we end up putting a lot of source of energy to keep us comfortable.  Weather is important too.  If we lived on Jupiter (if we could live on gas surface) we would be continously bombarded by electrical and hurricane type weather.  Or the chemical structure of atmosphere as first condition listed if it was a methane storm we would be undoubtedly dead.\n\nEasy geology.  Remember the movie "Armageddon"?  The rocky terrain jutting up with sharp points of the asteroid would make it hard to traverse the area.  Also from previous point the surface of the planet needs to be solid...Jupiter as a gas giant makes it hard to live on that.  Soil composition is important in regards to sustaining life in soil for vegetation.\n\nWhich from that point any form of vegetation is important to our survival.  We could build biodomes and such but if had to live using sources from the planet to help we would have to counteract any harmful levels (i.e. too much sulfur) to make it workable.  Also water is the most important essential needed (outside of oxygen).  Any way to form that materials on the planet or it should be existing already.\n\nFinally magnetic field is important to help ionizing levels of radiation occuring from any solar activity.  Having the dynamo which means planet with a central core of molten iron in a circumvent can help make the field.\n\nThere are numerous other conditions but these seem the obvious big ones.
