Flashcards in %Landforms, etc Deck (19):
T OR F: Metamorphic rocks that formed deep below Earth’s surface sometimes can be located near the tops of mountains.
T OR F: Mountain ranges can form over long periods of time through repeated collisions between plates.
What are the four processes of mountain building?
Converging plates, collisions and rifting, weathering, erosion and uplift
What are the four types of mountains?
Folded Mountians, fault-block mountains, uplifted mountains, and volcanic mountains
What are folded mountains?
Folded mountains are made of layers of rocks that are folded.
What are fault-block mountains?
Fault-block mountains are parallel ridges that form where blocks of crust move up or down along faults.
What are uplifted mountains?
When large regions rise vertically with very little deformation, uplifted mountains form.
What are volcanic mountains?
As molten rock and ash erupt onto Earth’s surface, they harden. Over time, many eruptions can build huge volcanic mountains.
T OR F: The centers of continents are flat and old.
T OR F: Continents are continually shrinking because of erosion.
What are the two ways continents get bigger?
1: continents get bigger is through the addition of igneous rocks by erupting volcanoes.
2: when tectonic plates carry island arcs, whole continents, or fragments of continents with them.
What is a plain?
A plain is an extensive area of level or rolling land.
What are basins?
Areas of subsidence and regions with low elevation are called basins.
Where do the world's largest oil and natural gas lie?
The world’s largest oil and natural gas fields lie in sedimentary basins.
What are plateaus?
Flat regions with high elevations are called plateaus.
How was the Grand Canyon created?
It was created as the Colorado River cut through and eroded the uplifting plateau. So, the Grand Canyon was created by water.
What is lava?
It is molten rock that erupts on Earth’s surface.
Which statement about plateaus and basins is correct?
A: Both are flat and found at high elevations.
B: Both are flat with plateaus having a high elevation; basins are found at low elevations.
C: Both are found at low elevations in mountain ranges.
D: Basins are flat but plateaus are very mountainous.
