Any of the sciences that deal with the Earth or its parts. The four major fields of study are: Astronomy- celestial bodies and the universe as a whole Meteorology – atmosphere and weather Geology – origin, history, and structure of the Earth Oceanography- physical and biological aspects of the oceans
The solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle.
The layers of the earth are the crust-mantle- outer core and inner core
The asthenosphere is a partially molten rock layer that allows for the lithosphere to float on top and. move
The watery layer of the Earth’s surface Lakes, rivers, oceans, seas, groundwater, glaciers, and water in the atmosphere 97% of the Earth’s water is salt water ¾ of the Earth’s fresh water is found in glaciers Most of the remaining ¼ is found in groundwater
The blanket of gases that surround a planet Protects the earth from harmful radiation Stabilizes planet temperature About 78% nitrogen About 21% oxygen About 1% carbon dioxide, water vapor and other gases
The region of the surface and atmosphere of the earth where living organisms exist along with the organisms that live there.
