When plates collide
convergent
100
Ocean plates move away from each other and new crust is formed
Oceanic Ridge
100
Two continental plates collide and are pushed upward. This creates ....
Mountains

Rivers and streams form a ________ on a topographic map.
V
200
Which layer of the Earth contains the crust
Lithosphere
200
where plates move sideways passing each other
Transform
200
when two plates collide and one is pulled underneath another. The plate melts and the magma rises creating....
volcanoes
200
When two plate slide past one another it creates....
Faults or earthquakes

When a hill is steep, the topographic lines are __________, but when a hill is more gentle or gradual, the lines are ________________.
close; wide
300
Which layer of the earth causes the plates to move? (which do they float on?)
asthenosphere
300
Where one plate is going underneath another
Subduction- Convergent
300
Two continental plate divide move apart from each other forming a .....
Rift Valley

What are two landforms found at divergent boundaries, not including fault.
Oceanic Ridge, Rift valley

Which two continents did Wegener think fit together like puzzle pieces?
South America and Africa
400
Where two plates are pushing towards each other
Convergent

Plates are moving together, forming a ring of volcanoes around the edge of the Pacific Ocean. This is called the...
Ring of Fire

What are two landforms that can form at a convergent boundary?
Trench, Mountain Range

If the V for a river is pointing to the left, where will the delta form.
at the right
500
How can you explain how the same fossils are found on both sides of the Atlantic Ocean?
Pangea- the continents were connected. The Atlantic ocean was not there.
500
Where two plates are moving away from each other in opposite directions
divergent
500
The land feature formed where one plate is subducting under another.
Ocean Trench

Which of the following is most likely found at a divergent boundary? fault, trench, mountain range, or rift valley
rift valley
500
When there is erosion of a river, what happens to the topographic map?
The V's get deeper
