Space

Question 1

day and night

Answer 1

If the axis wasn’t tilted, we wouldn’t have 12 hours of day and night

Question 2

what determines the year length

Answer 2

the time that it takes for a planet to one revolve around the sun

Question 3

How does season work?

Answer 3

Seasons occur because of the tilt of the Earth. When the part of the Earth you live on is tilted towards the sun, it is Summer and if you are tilted away from the sun, it is winter.

Question 4

Order of planets

Answer 4

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune

Question 5

Constellation

Answer 5

A group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure.

Question 6

Earth’s rotation

Answer 6

The Earth rotates from East to West (anticlockwise).

Question 7

Axial tilt

Answer 7

23.5

Question 8

Distance from the sun

Answer 8

The temperature of a planet is determined by how much energy they receive from the sun

Question 9

Atmosphere

Answer 9

Atmosphere= This system relates to meteorological features and phenomena such as weather, clouds, or aerosols (particles in the air).

Question 10

Biosphere

Answer 10

Biosphere= This system is associated with living systems such as biomes or ecosystems.

Question 11

Hydrosphere

Answer 11

Hydrosphere= This system is associated with water in solid (ice) and liquid states

Question 12

Litho/Geosphere

Answer 12

Litho/Geosphere= This system is associated with solid portions of the Earth.

Question 13

Crust

Answer 13

The outer layer of the Earth made up of solidified rocky plates.​ This is the layer you live on. It is 8-65 km thick.​

Our planet is divided up into big slabs of rock called PLATES.

Question 14

Mantle

Answer 14

The layer of molten rock on which the crust floats

Question 15

Outercore

Answer 15

Liquid iron and nickel

Question 16

Innercore

Answer 16

solid iron and nickel

Question 17

theory of continential drift

Answer 17

220 million years ago all the worlds continents were formed together to make one super continent called Pangea which slowly frifted apart over time

Question 18

what were the three stages of continential drift?

Answer 18

Pangea, Laurasia and Gondwana, and Modern world

Question 19

convection

Answer 19

When liquid or gas is heated, it expands, becomes less dense and rises. ​
The cooler liquid or gas drops down. The process then keeps going. ​
In Earth’s case, it’s the heating and cooling of the mantle. Hot mantle rises towards the crust while the cool mantle sinks back down to be reheated. This cycle continues

Question 20

convection currents

Answer 20

The convection currents in the liquid mantle generated by heat from deep inside the core cause the Earth’s plates to move.​
The Earth’s crust is broken up into pieces called plates​
The plates can move towards, away or slide past one another​
This movement is called plate tectonics and cause hazards like volcanoes and earthquakes.​
