100
This sphere includes all living things.
Biosphere
100
Name the first layer of the atmosphere, and give TWO things that are found there.
Troposphere
Biosphere, hydrosphere, geosphere, weather, airplanes, people, etc...
100
Describe how the Earth rotates and how long it takes.
Earth spins on its axis in 24 hours.
100
A group of related objects or processes that work together to form a whole.
System
100
How much of the Earth is covered by the hydrosphere?
About 70%
200
This sphere contains all of the water on Earth.
Hydrosphere
200
Name the second layer of the atmosphere, and give TWO things that are found there.
Stratosphere
Weather balloons, ozone layer, military jets, Felix Baumgartner, etc...
200
Describe how the Earth revolves and how long it takes.
Earth revolves around the Sun in 365.25 days.
200
A system that exchanges both matter and energy with the surroundings.
Open System
200
What happens to the air in the troposphere as you increase in altitude? (ex: when you climb a mountain)
Air gets colder and thinner (less air)
300
This sphere contains all of the gases surrounding Earth.
Atmosphere
300
Name the third layer of the atmosphere, and give TWO facts about this layer.
Mesosphere
Meteors break up in this layer, coldest layer.
300
Describe the motion of the moon using either rotate or revolve.
The moon revolves around the Earth.
300
A system that exchanges energy but NOT matter with the surroundings.
Closed System
300
How much is Earth's axis tilted?
23.5 degrees
400
This sphere contains all of the non-living, solid parts of the Earth.
Geosphere
400
Name the fourth layer of the atmosphere, and give TWO things that are found there.
Thermosphere
Auroras (northern & southern lights), space shuttle, satellites
400
Draw the position of the Earth and Sun when it is Summer in the Northern Hemisphere.
400
To spin on an axis.
Rotate
400
Explain how a volcano would affect at least 3 of the four spheres.
A volcano would erupt lava, ash, and smoke from the geosphere. The ash and smoke would go into the atmosphere. The eruption can damage and kill plants and animals in the biosphere. The eruption can also pollute any parts of the hydrosphere that are near the volcano, like lakes and rivers .
500
Name all four spheres
Biosphere
Hydrosphere
Atmosphere
Geosphere
500
Name the fifth layer of the atmosphere, and explain what it is.
Exosphere
Extends to space
500
Draw the position of the Earth and Sun when it is Summer in the Southern Hemisphere.
500
To orbit around another object.
Revolve
500
Explain how an earthquake would affect at least 3 of the four spheres.
An earthquake occurs in the geosphere, cracking the solid crust of the Earth. Earthquakes can injure or kill animals and plants in the biosphere. Earthquakes can cause fires, which can pollute the atmosphere. The hydrosphere can be disrupted by the changes in the land, and can be polluted by damaged buildings and fires.
