Question 4

Define gravity and understand how it differs on other planets.

Answer 4

Gravity is a force that exists everywhere. It pulls all things with mass or energy toward one another. Planets weigh different amounts, explaining why the force of gravity is different from planet to planet.

Question 5

Describe how day and night occurs.

Answer 5

Our planet spins on an invisible line — called ‘an axis’. Half of the Earth is always facing the Sun, meaning it is lit up. The other half is in darkness until the planet turns around.

Answer 6

A satellite, for example the Moon is a natural satellite of the Earth but communication satellites are artificial satellites of the Earth, is any object that is in orbit around a planet.

Answer 7

The moon is the earth’s natural satellite and a non-luminous object.

Question 8

Describe how a lunar eclipse occurs and be able to draw a diagram.

Answer 8

An eclipse of the Moon occurs when the Earth lies directly between the Sun and the Moon and the Moon lies in the shadow of the Earth.

Question 9

Describe how a solar eclipse occurs and be able to draw a diagram.

Answer 9

A total solar eclipse happens when the Moon casts the darkest part of its shadow, called the umbra, on Earth.

Question 10

Describe how shadows form and how they differ depending on the time of day.

Answer 10

A shadow is a dark shape made when light is stopped or blocked by an object or a person. The earth moves around the sun and, depending on the time of day, shadows formed by its light will be longer or shorter.

Question 11

Describe how the seasons occur and be able to label a diagram of the earth and sun in each season.

Answer 11

As Earth moves through its orbit around the Sun, different parts of the planet are tilted closer or further from the Sun, because of the tilt in Earth’s axis. It is the angle of the Earth’s tilt that causes the seasons: spring, summer, autumn and winter.
