2.  Earth is 3 rd planet from the sun  Part of the inner planets because it is made of rock

4.  Biosphere contains all the land, water, air, and living organisms. 1.Lithosphere = land 2.Hydrosphere = water 3.Atmosphere = air

5. 1. Lithosphere: walk, drive, ride bike 2. Hydrosphere: drink, swim, shower 3. Atmosphere: breathe, travel (plane)

6.  Organisms take what they need (food, water) from the biosphere

7. 1. Biosphere: the combined parts of the lithosphere, hydrosphere, and atmosphere in which life exists

8.  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

10. 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

12.  Supports life because many organisms depend on water for survival and it regulates temperature  (holds heat)

13.  Salt water = 97%  Fresh water = 3%  *however, a lot of fresh water is trapped in ice

14.  Most living things depend on fresh water for survival  It determines how many organisms can live in one area

15.  Water in the artesian well comes from an aquifer

16. 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

18. 1. Temperature regulation 2. Blocks harmful UV rays (ozone) 3. Contains the air we breathe

19.  Nitrogen = 78%  Oxygen = 21%  Carbon =.04%  *plants need carbon dioxide for photosynthesis in order to produce oxygen

20. 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

21.  The air is thinner which means there is less oxygen to breathe

22. 1. Troposphere, Stratosphere, Mesosphere, and Thermosphere  see your notes! 2. Ozone: an oxygen gas containing three oxygen atoms per molecule
