Chapter 1 RAD Guide
Earth is 3rd planet from the sun
Part of the inner planets because it is made of rock
Where is Earth located in our solar system? What group of planets is Earth a part of and why?
Supports life because many organisms depend on water for survival and it regulates temperature
How does the presence of liquid water on Earth support life?
1. Temperature regulation2. Blocks harmful UV rays3. Contains the air we breathe
Describe the role that our atmosphere plays in supporting life on Earth.
Organism: any living thing Lithosphere: the layer of land that forms
Earth’s surface 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
VOCABULARY!!
1. Igneous: liquid rock that has cooled◦ Example: basalt, granite, obsidian
2. Sedimentary: rocks that have been compressed over time
◦ Example: stalagmites, limestone, sandstone, shale
3. Metamorphic: rocks formed by heat and pressure
◦ Example: marble, slate, schist
Describe the 3 types of rock. Provide examples of each.
Salt water = 97%
Fresh water = 3%
What percentage of the hydrosphere is salt water? Fresh water?
Most living things depend on fresh water for survival
It determines how many organisms can live in one area
Why is fresh water so important to living things? How does the amount affect living things?
Water in the artesian well comes from an aquifer
What is the relationship between an aquifer & an artesian well?
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
4. Aquifer: an underground layer of porous rock that contains water
5. Artesian well: a well in which water flows to the surface due to high pressure underground
VOCABULARY!!
The air is thinner which means there is less oxygen to breathe
People who live at sea level have trouble breathing at tops of high mountains. Why do you think this is true?
Nitrogen = 78%Oxygen = 21%Carbon = .04%
Name the major gases in the atmosphere & their amounts.
1. Troposphere: touches the Earth, weather occurs here, water vapor, most gasses
2. Stratosphere: contains the ozone layer
3. Mesosphere: coldest layer (-100o C)
4. Thermosphere: hottest layer, very low air pressure
Describe the 4 layers of the atomosphere.
1. Troposphere, Stratosphere, Mesosphere, and Thermosphere see your notes!
2. Ozone: an oxygen gas containing three oxygen atoms per molecule
VOCABULARY!!
Biosphere contains all the land, water, air, and living organisms. 1.Lithosphere = land2.Hydrosphere = water3.Atmosphere = air
Describe what the biosphere is in your own words.
1. Lithosphere: walk, drive, ride bike
2. Hydrosphere: drink, swim, shower
3. Atmosphere: breathe, travel (plane)
List 2 ways that you interact with each of the parts of biosphere.
Organisms take what they need (food, water) from the biosphere
Describe the relationship between the biosphere and the organisms that live in it.
1. Biosphere: the combined parts of the lithosphere, hydrosphere, and atmosphere in which life exists
