Tragic Tectonics Thickers vocab

Question 1

Define

The Kármán line

Answer 1

A line defining the end of the Earth’s atomsphere, and the beginning of space.It is said to be at 100Km

Question 2

Define

Atomsphere

Answer 2

A collection of gases, above a celestial body’s surface, held by it’s gravity

Question 3

Define

Crust

Answer 3

The outermost layer of a planet, often made of rock.

Question 4

Define

Continental Crust

Answer 4

Crust, found over continental plates of a planet, which makes it’s land.It is thicker than oceanic, having an average thickness of 30Km, but weaker , as it is only carrying air.

Question 5

Define

Oceanic crust

Answer 5

Crust found under the oceans of a planet, which forms the ocean beds.It is much thinner than continental , being only 10km on average, but is much stronger, as it carries the weight of the planet’s oceans.

Question 6

Define

Plate tectonics

Answer 6

Moving parts, which float on the planet’s mantle, that makes up the crust

Question 7

Define

Continental plates

Answer 7

Moving parts on the planet’s mantle, that makes up the continents

Question 8

Define

Oceanic plates

Answer 8

Moving parts , that float on the planet’s mantle, that make up the ocean beds

Question 9

Define

Plate boundaries

Answer 9

The boundaries between two or more plate tectonics.

Question 10

Define

Divergent boundary

Answer 10

A plate boundary, with two plates moving away from eachother

Question 11

Define

Convergent boundary

Answer 11

A plate boundary, with two plates moving towards eachother

Question 12

Define

Conservative boundary

Answer 12

A plate boundary, with two plates moving beside eachother

Question 13

Define

Mantle

Answer 13

The second,and thickest layer of planet, made of liquid rock(Magma) 1630km thick in total.

Question 14

Define

Upper mantle

Answer 14

The upper layer of the mantle , which is responible for convection currents and earthquakes.410Km thick

Question 15

Define

Lower mantle

Answer 15

The lower layer of the mantle, responible for volcanoes and hotspots.1220Km thick

Question 16

Define

Convection current

Answer 16

Spinning cycles of warming and cooling magma, which are responsible for moving the plates

Question 17

Define

Hotspots

Answer 17

Parts of the mantle that is hotter than others, responsible for volcanic chains.

Question 18

Define

Lithiosphere

Answer 18

A term used to describe the upper,cooler layers of the planet

There is no defined term, but people usually consider the crust and upper manlte to be the lithiosphere

Question 19

Define

Asentosphere

Answer 19

A term used to describe the lower, hotter layers of a planet

Usually, the lower mantle and core

Question 20

Define

Core

Answer 20

The central part of a celestial body, responible for it’s gravitational and magnetic field

Question 21

Define

Outer core

Answer 21

The outer layer of the core , made of liquid metals, and resposible for the magnetic field.2200Km thick

Question 22

Define

Inner core

Answer 22

The inner layer of the core, made of solid metal, due to extreme pressure/heat.Responsible for gravitational field.1,220Km.
