Sciences

Although in most places science is taught as different disciplines, actually, it's all connected! In order to do research in the Earth and space sciences - also sometimes called the "geosciences", you need to have a strong background in all the sciences, as well as in mathematics, too. In this section, we have brought together information related to the Earth and space sciences from across our website on the different scientific disciplines. Explore these links to find out more about geology, physics, chemistry, and biology.
Daniel Wolf Savin, a senior research scientist at Columbia University's
Astrophysics Laboratory, has published a paper on the research he and his
colleagues have done on how stars began. They learned that hydrogen and
helium produced all other
<a href="/physical_science/element.html&dev=1">elements</a> in
the <a href="/the_universe/the_universe.html&dev=1">universe</a>.

planet has. And our planet keeps records of what happened. The oldest
records that the
<a href="/earth/earth.html&dev=1">Earth</a> keeps
are in its
<a href="/earth/geology/sed_intro.html&dev=1">rocks</a>.

explain why climate changed abruptly 635 million years ago.<p><small><em>                    Courtesy of Martin Kennedy, UCR</em></small></p>Everything you see around you is made of tiny particles called <a href="/physical_science/physics/atom_particle/atom.html&dev=1">atoms</a>.

During this time up to 48 volcanic eruptions were identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice.
