Which statement best describes our current ideas about the Solar System?

The planets all move in elliptical orbits around the Sun

The Sun feels warmer in summer because

the Sun’s rays are more concentrated

Which is the best description of a constellation?

a group of stars that appear to be close to one another

Which statement is not true?

Only large objects like the Earth produce a force of gravity

The Sun rises and sets every day because:

the Earth spins on its axis once every 24 hours

Which statement is not true?

A south pole repels a north pole

we cannot always see all of the lit part of the Moon

an area around a magnet where it attracts magnetic materials

Which statement is true?

In Britain we get more daylight in summer and less in winter

Why do we believe that our current model of the Solar System is correct?

It can accurately predict the movements of the planets

10kg
1N
1kg
10N
5
The Sun feels warmer in summer because
the Earth is further away from the Sun
the Sun’s rays are more spread out
the Earth is closer to the Sun
the Sun’s rays are more concentrated
6
We have different seasons during the year because
the Sun moves around the Earth
the Earth’s axis is tilted
the Moon moves around the Earth
there are 12 months in the year
7
Which is the best description of a constellation?
a group of planets that appear to be close to one another
millions of stars that form a spiral shape
a group of stars that appear to be close to one another
lines in the sky that join stars to each other
8
Which statement is not true?
Only large objects like the Earth produce a force of gravity
Your body is attracting the Earth
You are attracting the ipad with a small force of gravity.
The Earth attracts objects because it has a large mass.
9
The Sun rises and sets every day because:
the Earth spins on its axis once every 24 hours
the Earth spins on its axis once every 12 hours
the Sun moves around the Earth
the Earth moves around the Sun
10
Which statement is not true?
A north pole repels a north pole
A south pole repels a south pole
A south pole repels a north pole
A north pole attracts a south pole
11
The Moon appears to be different shapes at different times because:
the Moon spins on its axis once each month
we cannot always see all of the lit part of the Moon
the Moon orbits the Earth
there is no air on the Moon
12
A magnetic field is:
an area around a magnet where it attracts magnetic materials
a piece of ground with lots of iron in it
the space around a magnet where it repels magnetic materials
the space around a magnet where it attracts all metals
13
Which statement is true?
We get less daylight in summer and more in winter
We get most daylight in the spring
Daylight and night are the same length in summer and winter
In Britain we get more daylight in summer and less in winter
14
Why do we believe that our current model of the Solar System is correct?
It agrees with religious ideas
We can see the elliptical orbits
It can accurately predict the movements of the planets
We have sent people to visit the Moon
15
The stars appear to move across the sky at night because:
the Earth is orbiting the Sun
the Earth is spinning on its axis
the Earth’s axis is tilted
the Earth is orbiting the Moon
16
Gravity:
gets less if two objects get further apart.
does not depend on distance.
gets stronger if two objects get further apart.
gets less if two objects get closer together.
17
Stars are:
all very close to the Earth
lumps of hot rock in space
balls of burning gas, like the Moon
huge balls of burning gas, like the Sun
18
