Answers
1
When one atom breaks apart and forms two smaller atoms and gives off energy as heat.
Nuclear Fusion
Radioactive Decay
Heat of Formation
Cosmic Microwave Background Radiation
2
Theory that Earth is broken into pieces that move around and change the surface of Earth.
Contracting Earth Theory
Nebular Theory
Big Bang Theory
Theory of Plate Tectonics
3
What is the biggest reason Wegener's idea of continental drift was not accepted in his lifetime?
He couldn't explain how the continents moved
It sounded too easy
He was a meteorologist, not a geologist
People thought he looked like a crazy man
4
The seafloor is youngest at which of the following areas?
Ocean trenches
Subduction zones
Right next to the coast
Mid-ocean ridges
5
Area where old crust is destroyed.
Seafloor spreading
Ocean trench
Mid-ocean ridge
Magnetic striping
6
What was the name given to the giant landmass that contained all of the continents together?
Pangaea
Middle Earth
Eurasia
Polylandmassia
7
How does this picture of the location of earthquakes support the theory of plate tectonics?
It shows the ocean gets just as many earthquakes as land
The earthquakes outline the boundaries of tectonic plates
It shows that earthquakes happen all over the world
It clearly identifies areas of seafloor spreading
8
The left over heat from when Earth was formed.
Nuclear Fusion
Heat of Formation
Cosmic Microwave Background Radiation
Radioactive Decay
9
This picture shows which of the following?

11
Area where new crust is formed.

Location of Rainforests
Seafloor Spreading Apart
Evidence from telescopes
13
This picture shows which of the following?

Subduction zones
18
Which of the following are evidences Wegener used to develop his idea of continental drift?
The location of earthquakes and volcanoes.
Evidence from seismic waves
Matching rock types on different continents
The continents fit together like puzzle pieces

Ocean trench
Subduction zones
Seafloor spreading
Magnetic striping
23
Which of the following are evidences Wegener used to develop his idea of continental drift?
