Q

Leap Year

A

Each year, we add 0.25 to our years until a leap year (which comes every four years).
e.g. year 1- 365.25, year 2- 365.5, year 3- 365.75 and year 4- 366
Then 365.25 again

Q

Lunar Month

A

The time it takes the Moon to orbit around the Earth (28 days)

20
Q

Solar System

A

The Sun with planets and other objects orbiting it. The Sun is at the centre of the Solar System.

21
Q

Light Year

A

The distance that light travels in a year

22
Q

Inner Planets

A

Mercury, Venus, Earth and Mars

23
Q

Satellite

A

Anything that orbits a planet

24
Q

Northern Hemisphere

A

The half of the Earth that is North to the Equator

25
Equator
An imaginary line around the middle of the Earth
26
Sun
The star that the Earth orbits around
27
Asteroid
A small lump of rock that orbits the Sun
28
Sphere
A ball-like shape
28
New Moon
The phase of the Moon when we cannot see the lit-up side
29
Earth
The planet we live on
30
Gravity
A fundamental interaction which causes mutual attraction of all objects with mass
31
What two factors affect the force of gravity between two objects?
Mass and distance
32
When it is daytime, our part of the planet is facing ....... the Sun
TOWARDS THE SUN
33
When it is night time, our part of the planet is facing .... from the Sun
AWAY FROM THE SUN
34
How many degrees is the Earth tilted at?
23.5 degrees
35
Equation for weight
Mass x Force
36
Mass
Measure of the amount of matter in an object
37
Weight
The force exerted on an object by gravity
38
How is the tilt of the Earth's axis responsible for the seasons and differing day length throughout the year?
When the North Pole is tilted towards the Sun, it's summer in the Northern Hemisphere, when the South Pole is tilted towards the Sun, it's winter in the Northern Hemisphere. As well as this, when a hemisphere is tilted towards the Sun it experiences longer days and shorter nights.
39
What causes the phases of the Moon?
One portion of the Moon is lit up by the Sun. As it orbits the Earth, it changes how much of the lit-up side we can see. Sometimes we see all of it (Full Moon), only a bit of it (Crescent Moon) or none of it (New Moon).
40
What is meant by gravitational field strength?
It's how strong the pull is that an object has on other objects
41
How does the moon orbit the Earth?
The Moon is constantly falling towards the Earth because of gravity, but also moving sideways fast enough to miss the Earth
42
How can planets orbit the sun and satellites orbit other planets?
The balance of gravity and inertia- if the force of gravity were too strong the satellite would fall into the thing it's orbiting, but if the force of inertia were too strong the satellite would fly off into space. The balance keeps it in regular orbit.
43
My Very Educated Mother Just Served Us Noodles
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune (order of the planets from the Sun)
44
How do tides work?
The Moon and Earth are equally attracted to eachother, so the Moon pulls on the ocean closest to it, making a bulge - causing high tide. However, the Moon is also still pulling the Earth a bit. When the Moon pulls the Earth, it leaves a partial bulge on the other side.
