Summer

Question 12

What is the inner core made out of?

Answer 12

Iron and Nickle, It’s a solid

Question 13

What is the outer core made of?

Answer 13

Liquid (Magma?)

Question 14

What helps deflect solar winds?

Answer 14

The earth’s magnetic force

Question 15

What can a convection current be compared to?

Answer 15

A lava lamp

Question 16

What are the three types of plate movement?

Answer 16

Divergent, Convergent, and Transform

Question 17

What happens when plates are Divergent?

Answer 17

They move away from each other

Question 18

What happens when plates are Convergent?

Answer 18

They move towards each other

Question 19

What happens when plates are Transverse?

Answer 19

They slide past each other

Question 20

What is the Trifecta of analyzing natural disasters?

Answer 20

Environmental, Societal, and Economic

Question 21

What are the types of plates?

Answer 21

Oceanic and Continental

Question 22

What happens when Continental + Continental plates collide?

Answer 22

There’s not much subduction, crust buckles and folds and creates mountains.

Question 23

What natural formations are caused by Continent / Continent plate collision?

Answer 23

Mountains

Question 24

What are some famous results of CC collision?

Answer 24

Rocky Mountains, Appalachian Mountains, Himalayan Mountains.

Question 25

What happens when Continental / Oceanic plates collide?

Answer 25

The oceanic crust subducts because it is denser and thinner, then melts and becomes magma, the magma then rises and breaks through the crust creating volcanoes.

Question 26

What natural formations are caused by Continent / Oceanic plate collision?

Answer 26

A series of volcanoes / Volcanic mountain chains

Question 27

What are some famous results of CO collision?

Answer 27

Cascade Mountains

Question 28

What happens when Oceanic + Oceanic crust collides?

Answer 28

One plate subducts, melts, the magma rises, breaks through the rust, and forms volcanoes.

Question 29

What natural formations are caused by OO collisions?

Answer 29

Volcanoes / a Volcanic Island arc

Question 30

What are some famous results of OO collision?

Answer 30

Japan, Aleutian Islands

Question 31

What is the importance of P and S waves?

Answer 31

They help us map the center of the earth

Question 32

Which type of wave cannot travel through liquids?

Answer 32

S waves

Question 33

What do divergent boundaries create?

Answer 33

New crust, earthquakes, and volcanism.

Question 34

Where are most divergent boundaries found?

Answer 34

In the ocean

Question 35

What are some of the most famous divergent boundaries?

Answer 35

Atlantic ridge, African rift valley

Question 36

What causes divergent boundaries to spread?

Answer 36

Convection currents

Question 37

Explain the process of a convection current

Answer 37

Gravity pulls cooler parts of the mantle downwards, then those parts heat up and rise due to less density. The cycle then repeats.

Question 38

What natural disasters do Transverse / Transform boundaries create?

Answer 38

Since there is no subduction no land forms, however it causes powerful earthquakes.

Question 39

Explain the process of how transverse boundaries create earthquakes

Answer 39

Friction builds due to pressure and when the plates slip it causes an earthquake.

Question 40

What are some famous results of transverse boundaries?

Answer 40

San Andreas Fault, CA

Question 41

Explain the process of an earthquake

Answer 41

Plates are pressed together with tremendous force, the pressure / energy is building due to convection currents and can cause a sudden slip along the fault / boundary. The sudden slip releases a bunch of energy.

Question 42

Why does aftershock occur?

Answer 42

After the plates slip they must come back / equalize again

Question 43

What is a hotspot?

Answer 43

A piece of the deeper mantle rises below the crust and creates volcanoes not along a plate boundary.

Question 44

What must occur for a Tsunami to be created?

Answer 44

The earthquake must be underwater and the sea floor must be displaced.

Question 45

What is a negative societal + environmental impact of Tsunamis?

Answer 45

Saltwater intrusion to freshwater, intrusion on aquifers.
