Answers

1
What is the main difference between oceanic and continental crust?
Continental crust is thinner and denser
Oceanic crust is thicker and less dense
Oceanic crust is thinner and denser
Continental crust is thicker and denser
2
What causes a tsunami to form?
Melting polar ice caps
Offshore earthquakes displacing water
Heavy rainfall
Strong winds over the ocean
3
What type of boundary is formed when two plates move toward each other?
Convergent boundary
Divergent boundary
Neutral boundary
Transform boundary
4
What occurs when two continental plates collide?
Creation of an ocean trench
Development of new oceanic crust
Formation of high mountain ranges
Formation of mid-ocean ridge
5
What typically forms at a divergent boundary between two oceanic plates?
Mountain ranges
Mid-ocean ridges
Rift valleys
Ocean trenches
6
Why are volcanoes unlikely at transform boundaries?
Faults do not allow magma to rise
Magma is consumed by the mantle
Magma is trapped in ocean trenches
Magma cools too quickly
7

The liquid layer of Earth's core
The atmosphere surrounding Earth
10
What is a transform boundary?
