The study of the makeup of the earth and the processes that change and shape it is called __________.

1

Which statement best explains the theory of plate tectonics?

1

Which of the following is the most accurate statement about myths?

Drag & drop each item to the correct location.

4

Draggable item		Corresponding Item
mantle		Earth’s largest and thickest layer; consists of very hot, very dense rock
crust		solid; made of very hot metal; may be nearly as hot as the sun’s surface; innermost layer
outer core		thin; rocky; outermost layer; two types: oceanic and continental
inner core		liquid; made of very hot metal

Select Yes if it is a characteristic of tsunamis or No if it is not.

	Yes	No
Tsunamis form when earthquakes occur in oceanic crust, causing the seafloor to shift.
Tsunamis travel fast—as much as 500 miles per hour.
Tsunamis are easy to stop as long as scientists have enough warning when they begin to form.
Tsunamis can grow to become as tall as a three- or four-story building.

Label each of the following volcano descriptions with the appropriate word

	active	dormant	extinct
a volcano that has not erupted for at least 10,000 years and is not likely to erupt again
a volcano that has erupted in the past 10,000 years and is likely to erupt again
a volcano that hasn’t erupted for a long time but could erupt again

1

Which of the statements best explains the relationship between earthquakes and faults?

4

Select Yes next to each item in the chart that Alfred Wegener’s continental drift hypothesis helped explain and No next to each item it did not help explain.

	Yes	No
long ago, Earth had one huge landmass called Pangaea
as continents moved apart, their climates changed
drifting continents actually moved due to tectonic plates
groups of plants and animals that once lived together were separated as the continents moved apart

2

Seafloor spreading is the process of oceanic plates moving apart very slowly. When the seafloor dips down as one tectonic plate slides under another, a narrow, extremely deep valley called a(n)__________ is created. When oceanic plates move away from one another and form cracks in Earth’s crust, an underwater mountain called a(n)__________ is created.

1

Moving apart, colliding, and sliding sideways past one another are three ways in which __________move. 

1

Draggable item		Corresponding Item
Richter scale		Numbers describe the intensity of earthquakes based on the largest seismic wave recorded.
Seismograph		Jagged up-and-down lines show the energy of seismic waves.
