Why was Wegener's theory originally rejected?

He didn't adequately explain the forces that move plates

Paleomagnetism helps us understand:

How the Earth's magnetic field has changed

Define uniformitarianism.

The past is the key to the present

What evidence does not support Wegener's theory?

The size of the Canadian Shield

The theory of plate tectonics differs from continental drift because:

It explains the role of the seafloor

A subduction zone is located where:

One plate is forced under another

What causes seafloor spreading?

The eruption of magma through weak zones in the crust

The difference between the inner and outer core is:

The outer core is liquid and the inner core is solid

What is a rift valley?

The area above a divergent boundary

14
A subduction zone is located where:

True
False
16
What causes seafloor spreading?
The eruption of magma along subuction zones
Gravity from the moon
The eruption of magma through weak zones in the crust
The collision of one continent with another
17
Convection involves:
The cycling of magma in the mantle
The movement of plates
The cycling of heat
Being accused of a crime
18
Continental drifting is:
The idea that plates move
The idea that plates stay put
The idea that plates spin
The idea that plates are just flat bowls
19
Transform boundaries occur when:
Plates slide past each other
A divergent boundary becomes convergent
A plate shatters
Two plates collide
20
The difference between the inner and outer core is:
The outer core is liquid and the inner core is solid
The outer core and inner core are both solid
