Plate Tectonics Quiz 11/17/15

Question 1

pangea

Answer 1

super continent (all of the continents when they were together)

Question 2

Panthalassa

Answer 2

super ocean (when all of the continents were put together it formed a huge ocean called Panthalassa )

Question 3

mid-ocean ridge

Answer 3

seams long mountain ranges that run along the ocean floor

Question 4

constructive forces

Answer 4

forces that construct or build up

Question 5

destructive forces

Answer 5

forces such as ice, rain, wind, and changing temperatures that were down or destroy lanmasses

Question 6

what are the six layers of the earth

Answer 6

inner core, outer core, mesosphere, asthenosphere, lithosphere, crust

Question 7

inner core

Answer 7

a dense ball of solid metal with extreme pressures

Question 8

outer core

Answer 8

a layer of molten metal surrounding the outer core makes the magnetic field that protects us from solar radiation

Question 9

lithosphere

Answer 9

brittle rock the most upper part of the mantle sometimes it comes up to the core

Question 10

asthenosphere

Answer 10

below the lithosphere the material is hotter and increasing pressure, it’s like a metal spoon, as a result, the part of the mantle is less rigid than the rock above. Over thousands of years this part of the mantle will bend like a metal spoon.

Question 11

mesosphere

Answer 11

beneath the asthenosphere, this is hot but more rigid. the stiffness of the mesosphere is the result of increasingly high pressure. This layer includes a region called the transition zone, which lies just beneath the asthenosphere. It also includes the lower mantle which extends down to the Earth’s core.

Question 12

what is heat transfer (what types are they)

Answer 12

Radiation, conduction, convection

Question 13

Radiation

Answer 13

Transfer of energy in rays (Ex: The Sun)

Question 14

convection

Answer 14

heat transfer by movement of a fluid

Question 15

conduction

Answer 15

Heat transfer through touching of materials

Question 16

Who is Alfred Wegener

Answer 16

A scientist who came up with the hypothesis of continental drift.

Question 17

What was Wegeners Hypothesis

Answer 17

That all of the continents used to be one giant landmass called Pangea.

Question 18

What was Wegener’s evidence

Answer 18

1. Puzzle pieces (Wegener found that all of the pieces looked like they could fit together). 2. Fossils (The Lystrosaurus). 3. Climate (A. Ancient Glacier evidence B. Coal it used to be good for coal; stretched from U.S to Europe). 4. Ancient Mountain Chains (Go from U.S Oceans; start in Europe).

Question 19

Who was Harry Hess

Answer 19

Harry Hess was on a ship with a crew of men and found out what Sea-floor Spreading, and that Wegener’s hypothesis really was correct.

Question 20

What did Hess find

Answer 20

Hess found what Sea-floor spreading does is it begins at a Mid-Ocean Ridge, which forms a long crack in the Oceanic Crust. Along the ridge, new molten material from inside the Earth rises, erupts, cools, and hardens to form a solid strip of rock.

Question 21

what are mid ocean ridges

Answer 21

mid ocean ridges are seamed formed mountain ranges that run along the middle of the Ocean Floor.

Question 22

what are deep ocean trenches

Answer 22

When the Ocean Floor plunges into deep under water canyons.

Question 23

What happens at a deep ocean trench

Answer 23

the oceanic crust bends downward.

Question 24

in the process of deep ocean trenches what happens

Answer 24

In a process of taking tens of millions of years, part of the ocean floor sinks back into the mantle at deep ocean trenches.

Question 25

what is subduction

Answer 25

the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle.

Question 26

what happens during the process of subduction

Answer 26

as subduction occurs, crust closer to a mid-ocean ridge moves away from the ridge and toward a deep-ocean trench. Sea-floor spreading and subduction often work together. They move the Ocean floor as if it were a giant conveyer belt.

Question 27

what are the three plate tectonic boundaries

Answer 27

divergent, convergent, and transfrom.

Question 28

what is a divergent zone and what does it do

Answer 28

it is a zone that pushes away from each other

Question 29

what is an example of a divergent zone

Answer 29

the mid-atlantic ridge

Question 30

what is a transform zone and what does it do

Answer 30

A boundary that goes up/down and slides against each other.

Question 31

What is an example of a transform zone

Answer 31

The San Andreas fault in California

Question 32

what is a convergent zone and what does it do

Answer 32

a convergent boundary is a boundary that has one plate going under another.

Question 33

what are the three types of convergent zones

Answer 33

continental crust vs continental crust, Oceanic crust vs Oceanic crust, or Continental vs Oceanic.

Question 34

what is denser oceanic crust or continental crust

Answer 34

oceanic crust

Question 35

what happens when to plates collide in a convergent zone

Answer 35

because the denser crust come out on top, that makes it because the oceanic crust is cooler and DENSER it comes out on top as it spreads away from the mid-ocean ridge.

Question 36

how do faults, volcanoes and mountain ranges

Answer 36

these get created because the plates collide, pull apart, and grind against each other.

Question 37

how does a rift valley get created

Answer 37

when pieces of Earth’s crust divert rift valleys form.

Question 38

what is an island arc

Answer 38

a bunch of islands near a trench
