Earth is 3 rd planet from the sun Part of the inner planets because it is made of rock
Biosphere contains all the land, water, air, and living organisms. 1.Lithosphere = land 2.Hydrosphere = water 3.Atmosphere = air
1. Lithosphere: walk, drive, ride bike 2. Hydrosphere: drink, swim, shower 3. Atmosphere: breathe, travel (plane)
Organisms take what they need (food, water) from the biosphere
1. Biosphere: the combined parts of the lithosphere, hydrosphere, and atmosphere in which life exists
Organism: any living thing Lithosphere: the layer of land that forms Earth’s surface (made of various rock types) Hydrosphere: the parts of the Earth that are made of water Atmosphere: the layer of gases that surrounds the Earth Ecology: the study of interactions among living and nonliving things
1. Igneous: liquid rock that has cooled ◦ Example: basalt, granite, obsidian 2. Sedimentary: rocks that have been compressed over time ◦ Example: stalagmites (from a precipitate), limestone, sandstone, shale 3. Metamorphic: rocks formed by heat and pressure ◦ Example: marble, slate, schist
Supports life because many organisms depend on water for survival and it regulates temperature (holds heat)
Salt water = 97% Fresh water = 3% *however, a lot of fresh water is trapped in ice
Most living things depend on fresh water for survival It determines how many organisms can live in one area
Water in the artesian well comes from an aquifer
1. Igneous Rock: rock that is formed when liquid rock solidifies and cools 2. Sedimentary Rock: rock that forms when layers of sediment compress & cement together 3. Metamorphic Rock: rock that have been transformed by heat & pressure
1. Temperature regulation 2. Blocks harmful UV rays (ozone) 3. Contains the air we breathe
Nitrogen = 78% Oxygen = 21% Carbon =.04% *plants need carbon dioxide for photosynthesis in order to produce oxygen
1. Thermosphere: hottest layer, very low air pressure 2. Mesosphere: coldest layer (-100 o C) 3. Stratosphere: contains the ozone layer 4. Troposphere: touches the Earth, weather occurs here, water vapor, most gas is present here 5. REMEMBER: The Moose Said Toot
The air is thinner which means there is less oxygen to breathe
1. Troposphere, Stratosphere, Mesosphere, and Thermosphere see your notes! 2. Ozone: an oxygen gas containing three oxygen atoms per molecule
