Who are the three people who helped to discover the theory of plate tectonics? You only need their last names.
Arthur Holmes
Harry Hess
Alfred Wegener
100
What are the three different types of plate boundaries?
What are... divergent, convergent, and transform boundaries
100
What types of mountains are there?
What are... fold mountains, block mountains, and volcanic mountains.
100
What are natural disasters that can happen as a result of plate tectonics?
Earthquakes, tsunamis, hurricanes, and volcanoes.
100
The thinnest layer of the Earth
What is... the crust
200
What evidence did Alfred Wegener use to support his theory of Continental drift?
He said continents were an only piece of land but then they were separated. He calculated the movement of locations on Earth using longitude and latitude
200
What are divergent boundaries?
What is... where new crust is made as the plates pull away from each other.
200
How are fold mountains formed?
When plates collide and go over one another, they are formed because the plates tend to buckle and fold.
200
How do earthquakes happen?
Two or more plates collide and earthquakes happen.
200
A number of rigid, but moving, pieces of Earth's surface.
What is tectonic plates.
300
Why do you think people didn't believe continental drift theory when Wagner first explained it?
He didn’t prove why continents were separated.
300
What are transform boundaries?
What is... where crust is neither produced nor destroyed as the plates slide horizontally past each other.
300
How are volcanic mountains formed?
The plates move and create volcanoes along the plate boundaries.
300
The Himalayan mountains are the result of a ___________________________ boundary.
What is convergent boundary
300
The theory that all continents are fragments of Pangaea now drifting apart.
What is the Continental Drift Theory.
400
Who were the two scientists that brought forth supporting evidence to Wagner's theory?
Who are... Harry Hess and Arthur Wagner.
400
What are convergent boundaries?
What is... where crust is destroyed as one plate dives under another.
400
How are block mountains formed?
When a fault block is raised or lifted, these are formed.

This person used sonar to map the bottom of the ocean and discovered the mid-ocean ridge in the Atlantic Ocean.
Who is Harry Hess
400
States that youngest rocks of ocean floor are at divergin boundaries, moving outward.
What is seafloor spreading
500
What was Harry Hess' and Arthur Holmes' evidence supporting Alfred Wagner's theory of plate tectonics?
What is... thermal convection in the earth’s mantle could cause continents to move, but the continents were “carried” by larger pieces of the earth’s crust called tectonic plates.
500
What are the types of convergent boundaries?
What are... oceanic-oceanic, continental-continental, and oceanic-continental
500
Earthquakes and Volcanoes are usually located in relation to these.
What is a plate boundary
500
What is the Ring of Fire?
What is... an area of large numbers of earthquakes and volcanic eruptions that encircles the Pacific Ocean and it is formed where the Pacific Plate collides with other tectonic plates.

Although the hottest layer of the Earth, this layer is solid metal.
