What are three basic layers of the earth from coolest to hottest?
100
sections of the lithosphere that move around as the earth heats up
What are tectonic plates?
100
Wegner
What is the name of the German scientist who came up with the Continental Drift theory?
100
two plates rubbing against each other called transforming boundaries
What is caused an earthquake?
100
Natural Resource is a naturally made material used by man
What is the definition of natural resource?
200
Lithosphere
What is the layer of earth where plates shift when the asthensosphere heats up?
200
Where to plates meet together
What are plate boundaries?
200
The theory that all the continents were once together as a "super continent" also known as pangea. But due to earth's activity like volcanoes, earthquakes, and sea-floor spreading the continents have moved away from one another to create the continents we have today.
What is the continental drift theory?
200
when two plates move away from each other making a divergent boundary
What is the cause of volcanoes forming?
200
A natural resource that is being used quicker than the earth can make it.
What is a non-renewable natural resource and give one example.
300
conduction
What is the name of the movement of heat in the mantle called?
300
convergent, mountain building
What is a boundary called when two plates come towards each other? what does this cause?
300
1 inch per year
What is the distance that the plates move each year?
300
A natural resource that renews itself faster than we can use it.
What is a renewable resource?
400
Mesosphere
What is a layer of the earth that is semi-rigid, causes the lithosphere to move, and is included as part of the mantle?
400
divergent, sea-floor spreading
What is the boundary when two plates move apart? what does this cause?
400
Yes, we know this based on fossil records.
Where there tropical plants and animals that once lived on Antartica? Explain.
400
Tennessee is not close to a coastline or fault line. We do have some small earthquakes in West TN because it is close to a fault line.
What is reason we have very few earthquakes in Tennessee?
400
a non-renewable energy source made from the remains of dead animals and plants. coal, natural gas, & petroleum
What is fossil fuel? Give 2 examples.
500
Because of how close the molecules are together due to the pressure on this section of the earth.
What is the reason for the inner core being a solid? Why is it not melted iron and nickel?
500
GPS
What is the technology we used to find out the plates move one inch a year?
500
Fossil mapping, rock similarities (age, layering) and shapes of the continents
What are the scientific evidence to support Wegener's theory?
500
This is were the plates once meet and it shows use their boundaries
What is the reason we find so many volcanoes and earthquakes on the coast?
500
MTM is a form of surface mining using explosives to blow up mountains for its coal cutting out the workers. Its a quick fix for getting coal in places like WV, TN, NC. Its environmental impacts include flooding, loss of trees and habitats, pollution, and loss of jobs.
What is Mountain Top Mining? What are the environmental impacts from this practice?
