Earth Systems

Question 1

Abiotic

Answer 1

A non-living thing in the environment

Question 2

Atmosphere

Answer 2

An envelope of gas that surrounds the Earth

Question 3

Bio

Answer 3

Bio means living

Question 4

Biosphere

Answer 4

The biosphere contains any living thing that is present on Earth

Question 5

Biotic

Answer 5

Any living thing within the environment

Question 6

Crust

Answer 6

The Earth’s crust is the outer layer of the planet. It sustains all life on Earth.

Question 7

Cryosphere

Answer 7

The cryosphere is an all-encompassing term for the portions of Earth’s surface where water is in solid form

Question 8

Greenhouse Gas

Answer 8

Greenhouse gases are gases in Earth’s atmosphere that trap heat and raise the temperature.

Question 9

Ground Water

Answer 9

Ground Water is water held underground in the soil or in pores and crevices in rock

Question 10

Lithosphere

Answer 10

The lithosphere is the solid outer layer of earth that contains all the sediment, rocks and formations that classifies it as the earths hard outer shell.

Question 11

Mesosphere

Answer 11

The third highest layer of the atmosphere. It is where meteors are found.

Question 12

Salinity

Answer 12

Salinity is the accumulation of salt in land and water to a level that damages the natural and built environment.

Question 13

Stratosphere

Answer 13

The stratosphere is the layer of earth made up of the ozone

Question 14

Tectonic Plate

Answer 14

Tectonic plates, large slabs of rock that divide Earth’s crust, move constantly to reshape the Earth’s landscape.

Question 15

Turbidity

Answer 15

Turbidity is a measure of the level of particles such as sediment, plankton, or organic by-products, in a body of water

Question 16

Thermosphere

Answer 16

The part of outer earth where satellites and space shuttles are found

Question 17

Troposphere

Answer 17

troposphere is made up of nitrogen, oxygen, argon an co2. The more closely packed the gases are the denser and stronger the gravity is.

Question 18

Upper Mantle

Answer 18

Extends below the crust to 410kms towards the earth’s core. Is composed of various minerals (mostly silicon, oxygen, magnesium and iron). Mostly flowing and molten.

Question 19

Water Vapour

Answer 19

Water vapor is a greenhouse gas, meaning it is a gas in Earth’s atmosphere that traps heat. Like carbon dioxide and methane, water vapor is composed of complex molecules that absorb some of the heat radiated from Earth’s surface and re-radiate that energy back to the planet.
