100
The largest kind of volcano
What is a shield volcano?
100
The person who first had the idea of moving continents
Who is Alfred Wagner?
100
These are huge pieces of crust and rigid upper mantle that fit together at their edges to cover the Earth's surface
What are tectonic plates?
100
These are solid materials made of mixtures or large aggregates of one or more minerals.
What are rocks?
100
These form when the forces acting on a rock exceeds the rock's strength
What is a fault?
200
This type of volcano creates the biggest explosion
What is a composite volcano?
200
The name of all the continents together
What is pangea?
200
These are created when continental crust begins separate
What are rift valleys?
200
This is when hot molten rock cools underground
What is an intrusive rock?
200
The type of wave that moves the fastest
What is a primary wave?
300
This is what debris less than 2 millimeters is called
What is ash?
300
This type of rock formation was separated during continental drift
What are mountain ranges?
300
This is when two plates collide and the denser plate goes under the less dense plate
What is subduction?
300
When hot molten rock cools above the surface
What is an extrusive rock?
300
This is a numerical rating system that measures the magnitude of an earthquake
What is the Richter scale?
400
These types of volcanoes are found at divergent boundaries and over hot spots
What are shield volcanoes?
400
Nothing could explain what forces moved large masses over large distances
Why was continental drifting rejected?
400
This boundary is when two plates horizontally slide past each other
What is a transform boundary?
400
The main two properties that igneous rocks are classified by
What is color and texture?
400
This is the measure of energy released from an earthquake
What is magnitude?
500
These are found on continents near convergent boundaries
What is a cinder cone volcano?
500
This evidence was found in lower parts Africa, India, Australia and South America
What are glacial deposits?
500
This is the boundary when two plates go towards each other
What is a convergent boundary?
500
The five different types of rock textures
What is glassy, fine, course, vesicular and porphyritic?
500
The point on the Earth's surface above the focus
What is the epicenter?
