Science

• earth surfaces
• atmosphere - gaseous layer surrounding the earth
• lithosphere - solid part of the earth that includes crust and upper mantle
• hydrosphere - water on or near the surface of the earth
• biosphere - living organisms that inhabit the earth
• geosphere - solid part of the earth, including rocks and minerals
• biosphere - living organisms and their interactions with non-living environment
• geology is the scientific study of the physical structure, composition, history, and processes of the earth's lithosphere.
• biosphere - living organisms, their habitats, and interactions with non-living environment
• geology is the scientific study of the physical structure of the earth's lithosphere (solid rock) and its history.
• the atmosphere is composed mainly of nitrogen and oxygen
• the atmosphere is composed mainly of nitrogen (78%), oxygen (21%) and argon (0.934%)
• crust - outermost layer of the lithosphere
• the hydrosphere consists of all bodies of water on Earth including oceans, seas, groundwater, rivers, lakes, ponds, ice caps, glaciers, and freshwater clouds
• mantle - layer between core and crust
• biotic factors - living things (plants, animals) that affect an ecosystem
• core - center of the earth
• abiotic factors - non-living components of an ecosystem
• ecological pyramid - graphical representation of energy flow through different trophic levels within an ecosystem
• the atmosphere is composed mainly of nitrogen (78%), oxygen (21%) and trace amounts of other gases such as carbon dioxide, argon, neon, helium, methane, krypton, hydrogen, xenon, ozone, and nitrous oxide.
• ionosphere - layer of charged particles above the troposphere
• atmosphere - gas surrounding the Earth
• atmosphere - gases surrounding the earth
• crust - outermost layer of the earth
• mantle - inner core of the earth
• atmosphere - gases surrounding the Earth
• atmosphere - gases surrounding the Earth that protect it from solar radiation
• hydrosphere - water on or near the surface of the Earth
• cryosphere - frozen parts of hydrosphere
• atmosphere - gases surrounding Earth that protect it from solar radiation
• hydrosphere - water on or near Earth's surface
