Plate Tectonics

Question 1

What are tectonic hazards?

Answer 1

Tectonic hazards are those hazards which occur as a result of earth movements below the surface of the Earth i.e. within the Mantle.

Question 2

List some examples of tectonic hazards.

Answer 2

Tectonic hazards include Volcanic Eruptions, Earthquakes and Tsunamis. (yk just the shaky things, like me in that test tmr)

Question 3

State True or False:The Earth is made up of many layers

Answer 3

True. What’s even a truer fact, the Earth is an onion.

Question 4

What does the harder crust contain and include?

Answer 4

The hard outer crust contains all life on the planet. It includes continental crust (Landmasses) and Oceanic Crust (Sea Floors). (damn I didn’t know domino’s HARD crust pizza contained all that)

Question 5

What is below the hard outer crust?

Answer 5

a semi-molten layer which is extremely hot (ooh like reigen?)

Question 6

This hot (reigen) layer is known as the…

Answer 6

CORRECT mantle. if you didn’t get it correct, well this is awkward

Question 7

How does the Mantle behave and why?

Answer 7

The mantle behaves like soft fudge or caramel candy whereby it slowly moves. This movement occurs as a result of the heat generated within the Mantle. (no joke, just crickets)

Question 8

What causes tectonic movements?

Answer 8

when the super hot (reigen) semi-molten rock moves as convection currents, circulating within the mantle

Question 9

Where does the mantle’s temperature reach the melting point of a rock and what is the melting point called?

Answer 9

Near its upper edges, somewhere between about 100 and 200 kilometers (62 to 124 miles) underground. The melting point of a rock is magma. (here’s a song I’m gonna make up on the spot- 100, 200, right in between near it’s upper edges it can be seen, that 62, 124 miles underground, right there, is right where magma is found)

Question 10

What is the asthenosphere? (Athena’s nose is where)

Answer 10

when the magma forms a layer of partially melted rock

Question 11

What do geologists believe?

Answer 11

Geologists believe this weak, hot, slippery part of the mantle is what Earth’s tectonic plates ride upon and slide across (we have cars, tectonic plates ride upon the mantle, man we’re outdated)

Question 12

But no now the mantle rides upon sumn, not literally, but here’s your question, Double Daily, for 2000 dollars, what is below the mantle. (cue jeopardy music)

Answer 12

the core (yk core4, core more, rotten to the core, well that joke was corely executed)

Question 13

What is the core made up of?

Answer 13

the Inner and Outer Core

Question 14

let’s bring some science, what is the state of matter of the inner core?

Answer 14

solid, like rock, not magma (see what I did there)

Question 15

True or false:The inner core spins a bit faster than the rest of the planet.

Answer 15

True, she a ballerina

Question 16

What’s the temp of the inner core?

Answer 16

intensely hot (damn like zendaya): Temperatures sizzle at 5,400° Celsius (9,800° Fahrenheit) That’s almost as hot as the surface of the sun, yep def zendaya

Question 17

Are pressures immense in the inner core?

Answer 17

Pressures here are immense: well over 3 million times greater than on Earth’s surface (come to naps, see the pressure here)

Question 18

What do researchers suggest? (ik bad question, could be anything)

Answer 18

Some research suggests there may also be an inner, inner core. It would likely consist almost entirely of iron

Question 19

what is the outer core made from and its state of matter?

Answer 19

The Outer core is liquid and made from iron and nickel, just in liquid form

Question 20

Where does it sit? (no not on a chair)

Answer 20

It sits from 5,180 to 2,880 kilometers (3,220 to 1,790 miles) below the surface (5-1-8-0 km to 2-8-8-0 km and now its 9:39 pm so now here we goooo, 3-double 2-0 to 1-7-9-0 and this in miles, yk so now here we goooo)

Question 21

What heats the outer core and how does the liquid churn?

Answer 21

Heated largely by the radioactive decay of the elements uranium and thorium, this liquid churns in huge, turbulent currents

Question 22

That motion generates what and, in turn, that what generates what?

Answer 22

That motion generates electrical currents. They, in turn, generate Earth’s magnetic field (oh, my guess was what)

Question 23

How long does it take for Earth’s magnetic field to reverse?

Answer 23

For reasons somehow related to the outer core, Earth’s magnetic field reverses about every 200,000 to 300,000 years (the geologists don’t even know haha)
