100
The model for the dynamic earth.
What is Plate tectonics?
100
This occurs when tension is built up in two large masses of rock (elastic potential energy) and it suddenly snaps.
What is an earthquake?
100
Made from sediments of igneous rocks that are buried and compressed.
What are sedimentary rocks?
100
All the living things in a given area.
What is an ecosystem?
100
75% of earth's surface is made up of this.
What is water?
200
Extremely large layers of rock that move deep underneath the earth’s surface
What are tectonic plates?
200
subsurface molten rock.
What is magma?
200
This cycle involves formation, weathering and destruction of rock both on and underneath the earth’s surface.
What is the rock cycle?
200
This protects us from the sun's radiation.
What is The ozone layer?
200
This process causes mountains to become shorter and less pointed over time.
What is erosion?
300
The name of the plate boundary when two plates are moving past each other
What is a transform plate boundary?
300
The steady flow of molten rock.
What is lava?
300
Marble is a common example for this type of rock.
What are metamorphic rocks?
300
Gases that result from industrial and automotive sources , including Sulfur Dioxide, Carbon Monoxide and other Hydrocarbons
What is air pollution?
300
The longest unbroken mountain range in the world.
What is the Mid-Atlantic Ridge?
400
Plate boundaries that can create a subduction zone.
What are convergent plates?
400
These can be caused when higher magnitude earthquakes occur near an ocean plate.
What are Tsunamis?
400
The top layer of continental rock is mostly composed of this type of rock.
What is Granite?
400
Temperature increase associated with trapping in the atmosphere.
What is the greenhouse gas effect?
400
This measures earthquakes by the amount of ground motion they cause.
What is the Richter scale?
500
Plate boundaries that can cause seafloor spreading.
What are divergent plates?
500
Energy transmitted as a wave through the ground that causes the ground to rise and fall.
What is a seismic wave?
500
The most common extrusive igneous rock.
What is Basalt?
500
The balance that must be set between living organisms in an ecosystem.
What is homeostasis?
500
The name scientists gave to the continents when they were all one over 200 million years ago.
What is Pangaea?
