Parts Of The Earth (Earth's Crust)

Front 1

Crust

Back 1

outermost part of the earth and is very thin compared to the other layers.

Front 2

Crust

Back 2

where the living organisms dwell in

Front 3

Crust

Back 3

it forms a very thin continuous layer that extends underneath the ocean and continents.

Front 4

Continental Crust and Oceanic Crust

Back 4

Two types of crust?

Front 5

Continental Crust

Back 5

mostly composed of different types of granites

Front 6

Continental Crust

Back 6

Geologists often refer to the rocks as “SIAL”, which stands for silicate and aluminum, the most abundant minerals.

Front 7

"SIAL" Silicate and Aluminum

Back 7

Geologists often refer to the rocks of the continental crust as “____”, which stands for ________ and ____________, the most abundant minerals in continental crust.

Front 8

Cratons

Back 8

are the oldest and most stable part of the continental lithosphere and are found deep in the interior of most continents.

Front 9

Oceanic Crust

Back 9

mostly composed of different types of basalts

Front 10

Oceanic Crust

Back 10

Rocks are referred to as “SIMA” which stands for silicate and magnesium, the most abundant minerals.

Front 11

"SIMA" Silicate and Magnesium

Back 11

Rocks of the oceanic crust are referred to as “____” which stands for ___________ and ____________, the most abundant minerals in oceanic crust.

Front 12

Mantle

Back 12

made up of silicates, magnesium oxide, iron, aluminum, calcium, sodium, and potassium.

Front 13

Upper Mantle and Lower Mantle

Back 13

Mantle are divided into two layers, what are those?

Front 14

Upper Mantle

Back 14

the solid part of the mantle.

Front 15

Lower Mantle

Back 15

the liquid part of the mantle.

Front 16

Mantle Plumes

Back 16

an upwelling of superheated rock from the mantle.

Front 17

Mantle Plumes

Back 17

likely cause of “hot spots,” volcanic regions not created by plate tectonics.

Front 18

Core

Back 18

dense center and hottest part of earth, and it is almost made entirely of iron and nickel.

Front 19

Gutenberg discontinuity

Back 19

is the boundary between the core and the mantle.

Front 20

Outer Core and Inner Core

Back 20

two types of Core?

Front 21

Outer Core

Back 21

borders the mantle. Bullen discontinuity is the hottest part of the core.

Front 22

Bullen discontinuity

Back 22

is the hottest part of the core.

Front 23

Outer core

Back 23

the liquid part of the core.

Front 24

Inner core

Back 24

the solid part of the core.

Front 25

Inner core

Back 25

is a hot, dense ball of iron. The temperature of the _________ is far above the melting point of iron.

Front 26

Bullen discontinuity

Back 26

is the boundary separating these two layers.
