Tectonic plates and topography overview
Which boundary includes 2 tectonic plates pushing against each other?
Convergent
What happens if a Continental plate and another continental plate collide with each other?
They push up against each other and forch each other up, creating mountain ranges.
What is a topographic map?
A map that shows elevation.
What causes earthquakes?
When tectonic plates collide and one gets pushed down.
What is an example of an activity that uses topographic maps?
Hiking
Which boundary involves 2 tectonic plates moving away from each other?
Divergent
Who proposed the Continental drift theory first?
Alfred wegener
What indicates a mountain peak on a topographic map?
Concentric lines getting smaller and smaller
What causes tsunamis?
When a tectonic plates shoots up after being pushed down.
What happens to tectonic plates when they are forced down by another plate?
Which boundary involves 2 plates sliding against each other?
Transform
What happens in a divergent boundary?
Magma gets pushed up through the gap and creates new crust.
What can never touch on a topographic map?
Contour lines
What causes continental drift?
Tectonic plates moving
Who created the first topographic map?
Charles Hutton
What determines an overhang on a cliff on a topographic map?
A dotted line
Which fault in California is moving in the opposite direction of the rest of the United States?
San Andreas fault
What indicates a lake on a topographic map?
A blue area and sometimes there is a steep descent.
What causes mountains to be made?
2 Continental plates pushing up against each other which causes them to go up and create mountains.
What was the evidence that alfred wegner used to find out about continental drift?
the fit of the continents, the distribution of fossils, the similarity of rock formations across continents, and evidence of past climates
What are the lines called that distinguish the steepness and the height of a mountain/hill on a topographic map?
Contour lines.
What happens if an oceanic plate and another oceanic plate collide?
It creates a subduction zone and makes a trench.
What indicates a river on a topographic map?
A blue line and the contour lines making a V shape when crossing
What causes volcanic eruptions?
When a subduction zone is created which melts the plate getting pushed down, causing magma to shoot up in an eruption.
Who was the famous cartographer that helped prove that continental drift was happening.
Marie Tharp
