Earth's Systems
These are Earth's 4 spheres.
What is the geosphere, hydrosphere, atmosphere, and biosphere?
This is the type of currents that cause warm fluids to rise and cold fluids to sink.
What are convection currents?
The scientist who proposed continental drift theory.
Who is Alfred Wegener?
This is the term for the balance between incoming energy from the sun and outgoing energy from earth.
What is energy budget?
This is one way humans have affected the atmosphere.
What is by burning fossil fuels? (or others)
This sphere includes all landforms, rocks, soil, and Earth's interior.
What is the geosphere?
These are the two parts of the mantle.
What is the lithosphere and the asthenosphere?
These were found in different continents, which proposed the idea that they were once connected. Mesosaurus is an example.
What are fossils?
Energy comes in to earth as this.
What is shortwave solar radiation?
This is one way humans have impacted the hydrosphere.
What is water pollution from industry, agriculture, and households? (or others)
Water vapor is included in these two spheres.
What is the atmosphere and the hydrosphere?
This plate boundary causes plates to move apart.
What are divergent plate boundaries?
This mountain range matches mountains in Greenland and Scotland
What are the Appalacian mountains?
This is when climate is stable.
What is when incoming energy equals outgoing energy?
This is one way humans have impacted the biosphere.
What is by habitat destruction, introducing invasive species, and overhunting/overfishing? (plus others)
This is how all 4 spheres would be affected by a volcanic eruption.
(answers vary)
This plate boundary results in volcanic arcs and earthquakes.
What are divergent plate boundaries?
These occur at plate boundaries.
What are earthquakes and volcanoes?
This is the reflectivity of a surface.
What is albedo?
This is one way humans impact the geosphere.
What is mining, drilling, soil erosion from agriculture, or land degradation from construction? (or others)
This is an example of how systems rely on each other.
(answers vary)
The hawaiian islands were formed from this geologic feature.
What are hot spots?
This piece of evidence comes from cooled rocks at mid-ocean ridges.
What is magnetic striping/magnetic reversals?
This is a process that amplifies or reduces change in a system.
What is a feedback loop?
These are pieces of evidence of climate change. (3 pieces of evidence)
What are rising global temps., melting glaciers and sea ice, and more frequent and extreme weather events?
