Our World in Motion: Answers



What causes the Earth’s tides?

• Gravitational pull of the Moon and Sun

Tides are the rise and fall of sea levels caused by the gravitational pull of the Moon and Sun.

The moving plates responsible for earthquakes and some volcanoes are called...?

• Tectonic plates

The Earth's crust is split into tectonic plates. They move around on the hot mantle, a bit like toast floating in hot beans. Tectonic plates rub against each other with great force, causing earthquakes and some types of volcanoes.



What causes the northern lights?

• Earth’s magnetic field

The northern lights, aurora borealis, are caused by charged particles emitted by the Sun hitting the Earth's atmosphere. The Earth's magnetic field deflects these charged particles to the north and south poles.

The weathering of rocks due to iceis called...?

• Freeze-thaw weathering

Water expands slightly when it freezes into ice. If water gets into a crack in a rock and then freezes, it expands and makes the crack even larger.

When the ice melts, more water enters the crack. The water freezes again and makes the crack even bigger. This freezing and thawing process continues until the crack becomes so big that a piece of rock falls off.



A day is...?

•The Earth spinning on its axis once

A day is the Earth spinning on its axis once. This is approximately 24 hours. A year is the Earth orbiting around the Sun once.


Animal Travel: Answers

What is the fastest animal in the world?

• Peregrine falcon

Although the cheetah is the fastest animal on land, the peregrine falcon can reach speeds of over 200 miles per hour when it goes into its hunting dive.



Sperm whales can dive to depths of...?

• 3,000 metres

Sperm whales can dive to 3,000 metres - that's nearly two miles. A sperm whale can stay underwater for over two hours before returning to the surface to take a breath.


True or false: no mammals can fly.

• False

Bats are mammals. They have wings and are able to fly. There are nearly 1,000 species of bats.

Arctic terns hold the record for the longest animal migration. Where do they migrate?

• Arctic to Antarctic

Arctic terns migrate from Arctic to Antarctic, a distance of over 22,000 miles! Arctic terns migrate between the poles to avoid the harsh winters.



Which animal has the biggest wingspan?

• Albatross

Wandering albatrosses have a wingspan of 3.5 metres. They need powerful wings as they spend most of their lives in flight.


Travelling Around Our World: Answers


Light travels from the Sun to Earth. How fast does it travel?

• 300,000,000 metres per second

It takes 8.3 minutes for light to travel from the Sun to Earth.


Cars use petrol, a type of fossil fuel. What problem does burning fossil fuels contribute to?

• Greenhouse effect

The greenhouse effect contributes to climate change and increasing the Earth's global temperatures.


The Montgolfier brothers invented the first hot air balloon. What were the first passengers?

• A sheep, a rooster and a duckThe Montgolfier brothers were worried about the effect of flying into the upper atmosphere, so theydecided to send a sheep, a rooster and a duck to test it out!


What is the only commercial vehicle to break the sound barrier?

• Concorde

Now retired, Concorde reached speeds of 1,350 miles per hour.


Which of these is a type of renewable energy?

• Solar energy

Oil and coal are both fossil fuels.


Our Body in Motion: Answers


True or false: when you're exercising, it takes your blood around ten seconds to get from your heart to your big to and back.

• True

When you exercise, your heart has to work harder to get oxygen around your body. It pumps more often to get blood around your body more quickly.


Red blood cells carry oxygen around your body. What holds onto the oxygen?

• Haemoglobin

Haemoglobin on red blood cells joins onto oxygen and carries it around the body. The oxygen is let go wherever it is needed in the body.


The hip joint is a type of...

• Ball and socket joint

It allows movement in more than two directions, unlike a hinge joint.


What controls which substances can get into and out of your cells?

• Cell membrane

The cell membrane controls Which substances can get into and out of your cells.


Infectious diseases are often caused by bacteria or viruses. What travels around your body protecting you against infectious diseases?

• White blood cells

White blood cells travel around your body and protect you from infectious diseases. Some white blood cells can engulf bacteria or viruses and kill them. Other white blood cells make antibodies that stick to bacteria or viruses.
