mountain

Question 3

Cinder cone volcano

Answer 3

Breaks into pieces cools and forms cinders around the vent

Question 4

Earthquake

Answer 4

The rolling, shaking, moving or shocking of the earths surface

Question 5

Hypocenter

Answer 5

Location on the fault where the movement first occurs

Question 6

Seismic waves

Answer 6

The source of an earthquake create seismic waves that travel outward.
Tectonic plates Are constantly moving and the strain along that fault becomes too much. The energy is rapidly released in the form of vibrations called seismic waves.

Question 7

Normal fault

Answer 7

When rocks pulls apart one side slips downward

Question 8

Reverse fault

Answer 8

The rocks push together, one side shifts up over the other, creating a reverse fault.

Question 9

Strike slip fault

Answer 9

When rocks slide past each other in opposite directions, a lateral or transform fault is created.

Question 10

Seismograph

Answer 10

A tool that graphs seismic waves. Is used to measure the direction, speed, and magnitude of earthquakes.

Question 11

Magna

Answer 11

When the heat inside the earth causes the rocks to melt,
a thick liquid called magna forms.

Magna rises to the surface and pushes through weak spots.

Question 12

Ring of fire

Answer 12

The edges around the plates of the Pacific ocean are subject to the most movement, and the most volcanoes and earthquakes

Question 13

Tectonic plates

Answer 13

The Earth’s crust consists of rocky plates that fit together like puzzle pieces. They are constantly moving

Question 22

Plates

Answer 22

The large sections that make up earths crust and upper mantle

Question 23

Folds

Answer 23

When plate slowly ran into each other, they can form bended rock layers called folds

Question 24

Fault

Answer 24

A long narrow crack in the Earth’s crust

Question 25

Mountains

Answer 25

Tall landforms caused by folding or faulting

Question 26

Earthquake

Answer 26

If the rock in the earths crust suddenly shakes an earthquake occurs

Question 27

Tsunami

Answer 27

Underwater earthquakes that cause huge ocean waves

Question 28

The travel of seismic waves

Answer 28

Seismic waves travel at different speeds along earth’s surface and through earths interior

Question 29

Volcano

Answer 29

A mountain that forms around an opening in earths crust

Question 30

Answer 30

Volcanoes that form over thin places in earth’s crust

Question 31

Hawaiian Islands

Answer 31

An example of volcanoes that formed over a hotspot in the Pacific ocean

Question 32

How is a volcano produced?
