Earth's Spheres
How many spheres does Earth have? What are they?
There are 4. The Geosphere, Atmosphere, Biosphere, and the Hydrosphere.
How may plate boundaries are there? What are they?
There are 3 different plate boundaries. There's Divergent boundaries, Transform boundaries, and Convergent boundaries.
What is climate change?
It's a change in global/regional climate patterns
What is a positive feedback loop?
A system that changes further the same way.
What does the Atmosphere contain?
It contains all of the air and oxygen on Earth.
What does a Transform boundary do and what physical feature does it make?
The boundary makes two plate tectonics slide past each other creating friction. This causes an earthquake, which is a fault.
What is the #1 factor of climate change?
The Greenhouse Effect
What is a negative feedback loop?
A system that changes in the opposite direction it was moving.
What does the Hydrosphere contain?
It contains all of the water on Earth.
What does a Divergent boundary do, and what physical features does it make?
Two plate tectonics pull away from each other. It creates ridges or rifts.
What is the Greenhouse Effect?
The Sun's rays are getting trapped in the atmosphere. There is more radiation in the atmosphere and there is also more carbon dioxide.
What is homeostasis
A process which organisms maintain a relatively internal environment.
What does the Biosphere contain?
It contains all of the plants, animals, and humans on Earth. All living organisms.
What does a Convergent boundary do, and what physical feature does it make?
Two plate tectonics crash into each other. This either creates trenches and volcanoes when it's a Continental plate and a Oceanic plate, creates mountains when it's two Continental plates, or it creates trenches/island arcs if it's two Oceanic plates.
What is happening because of climate change?
The Earth is warming up and the polar ice is melting.
What is one example of a positive feedback loop?
Sea-ice polar ice caps melting, and permafrost melting.
What does the Geosphere contain?
It contains all of the rocks and mountains on Earth.
Name where all of them can be found in the world.
Divergent: Mid Atlantic Ridge/Iceland
Convergent: (Cont./Oce.) Andes Mountains/Western Coast S.A, (Cont./Cont.) Himalayas, (Oce./Oce.) Japan/Philippines
Transform: San Andres Fault in California
How are humans impacting climate change?
We drive cars everywhere releasing more C02 into the air. We are also cutting down forests, and trees take in C02 and put out oxygen.
One example of a negative feedback loop
