1. Bell ringer (write the question)
Write the appropriate label for each letter (use one of the following words Radiation, convection, or conduction)
True/false the transfer of heat by direct contact is known as convection
True/false radiation is the transfer of heat energy by electromagnetic waves

2. What are the earth’s spheres?
 Everything in Earth's system can be placed into one of five major subsystems: land, water, ice,living things, or air. These five subsystems are called "spheres”
Geosphere
Hydrosphere
Cryosphere
Biosphere
Atmosphere

3. What is the geosphere?
The mostly solid, rocky part of Earth. It extends from the center of the earth to the surface.
Includes
Mountains, rocks, soil

4. Which layer are we located on?
The crust

5. What do we know about water?
Water can be a gas, a liquid, or a solid, and can go back and forth from one state to another
Water can shape the earth through erosion and deposition

6. What is the hydrosphere?
part of Earth that is liquid water.
Oceans, lakes, rivers, marshes, and groundwater

7. What is the difference between the cryosphere and the hydrosphere?
made up of all of the frozen water on Earth.
Snow, ice, sea ice, glaciers, ice shelves, icebergs, and frozen ground are all part of the cryosphere
Hydrosphere
Liquid water on earth

8. What is the atmosphere?
A mixtures of mostly invisible gases that surrounds earth
Contains the air we breathe
Other parts of the atmosphere cause space debris to burn up before reaching Earth’s surface.

9. What is the biosphere?
The biosphere makes up all the living things on earth
Plants, animals, humans, etc.

10. What spheres do you see in this image

11. Earth system
All of the earth spheres interacting with each other (working together) make up the earth system.

12. 12/06-12/07 (write questions)
What is the Atmosphere?
What is the biosphere?
Which spheres are interacting when a volcano erupts and releases gasses into the air?
Emperor penguins spend time on land, and need to breathe oxygen from the air. These penguins also swim and hold their breathe for about 18 minutes as they hunt for fish.
How do these organisms interact with each of earth’s sphere?
Period 5/7

13. What is the atmosphere?
A mixtures of mostly invisible gases that surrounds earth
Contains the air we breathe
Other parts of the atmosphere cause space debris to burn up before reaching Earth’s surface.

14. What is the biosphere?
The biosphere makes up all the living things on earth
Plants, animals, humans, etc.

15. How do these organisms interact with each of earth’s sphere?
Penguins are living things and belong to the biosphere; they live on the geosphere and the cryosphere; they swim and go hunting in the hydrosphere; they breathe air in the atmosphere.

16. What is the air composition of the atmosphere?
78% Nitrogen
21% oxygen
1% other gases

17. What are the layers of the Atmosphere?
Troposphere
Stratosphere
Mesosphere
Thermosphere

18. Which spheres are interacting when a volcano erupts and releases gasses into the air?
The Geosphere
The volcano
The atmosphere
The gases in the air released by the volcano.
Biosphere
Animals having to find shelter due to volcanic eruptions

19. Troposphere Includes All living organism
This is the layer where weather occurs
As altitude increases, temperature decreases.
clouds

20. Stratosphere Planes usually fly in this layer Contains ozone
The gas molecule responsible for absorbing UV light from the sun
Found in the ozone layer

21. Mesosphere Meteoroids begin to burn up in this layer Coldest layer
Due to ice crystals found in this layer
Coldest layer
As altitude increases temperature decreases

22. Thermosphere The hottest layer in the atmosphere
The northern lights occur in this layer

23. 12/10-12/11write the question
Explain the importance of the mesosphere?
What would happen to life on earth if the ozone layer was not present?
Cloudy nights are often warmer than clear nights. Why do you think that is the case?

24. Explain the importance of the mesosphere
Meteoroids begin to burn up in this layer
Coldest layer
As altitude increases temperature decreases

25. What would happen to life on earth if the ozone layer was not present?
With no ozone layer, earth will be exposed to more UV rays from the sun

26. Cloudy nights are often warmer than clear nights
Cloudy nights are often warmer than clear nights. Why do you think that is the case?
Clouds trap heat

27. What is the geosphere?
The mostly solid, rocky part of Earth. It extends from the center of the earth to the surface.
Includes
Mountains, rocks, soil

28. What are the compositional Layers of the earth?
Crust
The outermost layer of earth
Mantle
Convection occurs in this layer
The middle layer of the earth
Core
The densest layer
Made up of nickel and Iron

29. What are the two types of crust? Which is denser?
Continental Crust
Most above sea level
Less dense
Oceanic crust
Located below sea level
Denser

30. What the physical layers of earth?
Lithosphere
AKA the Crust
Mesosphere
Upper mantle
Asthenosphere
Lowe mantle
Outer core
Liquid layer of the core
Inner core
Solid densest layer of the core

31. Lithosphere
The lithosphere is made of the crust and the rigid upper part of the mantle
The lithosphere is divided into pieces called tectonic plates

32. Asthenosphere Vs. Mesosphere
Upper mantle, weak soft mantle
Made up of solid rock
Mesosphere
Strong lower mantle
Rocks flow more slowly in this layer
