Geological Change
100
The coolest and thinnest layer.
What is the crust?
100
Name for the area between plate boundaries
What is a fault?
100
A force acting on rocks found at the surface.
What is weathering?
100
The origin of all rocks.
What is Magma?
100
Geological forces forming this rock type.
What is heat and pressure?
200
Identified as one layer, it is noted as having an "inner" and an "outter" region.
What is the core?
200
The name given to the land form that included all the continents 240 millions years ago
What is Pangaea?
200
Heat, pressure and plate tectonics are responsible for making this type of rock.
What is metamorphic rock?
200
Three forces needed to change from Igneous to Metamorphic.
What are buried deep, heat, and pressure?
200
Responsible for rounding mountain tops and carving valleys.
What are glaciers?
300
The thickest region of semi-solid rock
What is the mantle?
300
This plate boundary typically produces earthquakes. Its most famous example is located in California.
What is a transform boundary?
300
Sedimentary rock comes from the root "sed" implying to sit or settle over time. Scientist refer to this process using this more sophisticated term.
What is compaction?
300
Forces needed to change from sedimentary to igenous
What is melting and cooling?
300
Weathering forces that break down rocks into sediments.
What are water, wind, temperature, and gravity?
400
A process of heating and cooling of liquid rock beneath the surface.
What are convection currents?
400
This plate boundary is known for producing trenches, volcanoes, and mountains.
What are converging boundaries?
400
Colorful, often containing crystals, or glass-like in appearance. This rock can be formed on intrusively or extrusively.
What is igneous rock?
400
Forces needed to change a metamorphic rock to a sedimentary rock.
What are weathering, erosion, deposition, compaction?
400
Forces at work, changing a rocks form.
What is weathering?
500
The primary element making up the earth's deepest layer and responsible for our north and south poles.
What is iron?
500
Diverging Boundaries, responsible for making new crust both on land and in the ocean, produce these types of land forms.
What are rift valleys and Mid Ocean Ridges?
500
Process where particles of rock are carried by water and placed in a low lying area.
What is deposition?
500
The ultimate force moving rocks to the surface if buried deeply, or forcing rocks deeper in the crust.
What are convection currents?
500
Two examples of geological evidence that supports plate movement over time.
What are fossils, continent shapes, and rock formations?
