Coasts

Coasts are where the land meets the sea.

The coast is shaped and changed by waves (eroding, transporting and depositing

material) – and humans!!

QUIZ! What do you think?1. The length of the UK coastline is around:

5000 miles 8000 miles 12000 miles

2. The place in the UK that is furthest from the sea is about 33 53 73 miles from the sea.

3. With holidays and trips each year it works out at more than 3 7 10 visits to the coast for very person in the UK.

4. The oceans occupy about 50% 70% 90% of our planet's surface

5. The average depth of the ocean is 2.5 5.5 7.5 miles

6. The oceans provide 19% 59% 99% of the Earth's living space

7. Mount Everest is shorter taller than the deepest point in the ocean

8. Can you match the locations to the coastline?Africa (Namibia), Australia, Caribbean, Greece, India, Japan, Norway, UK, USA

Waves• The wind causes waves on the surface of the ocean. Waves

are the main way in which the sea erodes, transports and deposits material. The wind transfers some of its energy to the water.

• The energy of a wave is determined by its height and length. Stronger winds cause larger waves.

• Wave height and length vary according to the speed and length of time a wave has been moving and the fetch (the distance of open sea over which the wind has blown).

• Near the coast, waves slow down in the shallow water, causing them to ‘break’ (becoming unstable). Seawater moving up the beach is swash, and moving back to the sea is backwash

What determines the size of the wave?

• the distance the wind blows (over open water) which is known as the "fetch",

• the length of time the wind blows• the speed of the wind.

• The movement of water particles in awave is circular, when the wave reachesthe shore the circle is broken and thewave spills forward - it breaks.

Constructive and Destructive Waves

What do you think CONSTRUCTIVE and DESTRUCTIVE waves are?

• CONSTRUCTIVE WAVES: build up a beach

• DESTRUCTIVE WAVES: remove material from a beach

Constructive (spilling) wavesArrive at a rate of about 6- 8 waves per minute

Normally on gently sloping beaches

Destructive (plunging) waves

Arrive at a rate of about 13 - 15 waves per minute

Normally on steeply sloping beaches

Home Learning: Outdoor Adventurous Activities

PE | Year 4 | Outdoor | Outdoor Adventurous Activities | Home Learning

1. Create a map of your garden, or a space within your home. Remember to include a key to show what the symbols in your map mean.

2. Compose a set of warm-up exercises to show your family and friends. Remember: the purpose of a warm-up is to raise your heart rate and loosen your joints. It is also meant to be fun!

3. Can you find different equipment around your house to create an obstacle course? This could be anything from cushions to spoons! Then, set up a small obstacle course to be completed by your family members. How could this course be made trickier?

4. Point of contact game. Gather your family and friends round and make a small team. You will be the teacher. You must instruct your team to have a specified number of specific body parts in contact with the floor. They must hold their position for five seconds. Who will be the winner? For example: All three points on the floor. This would be similar to the artic fox position in yoga.

5. What is the history of Outdoor Adventures? Research this sport and create a timeline to show other children your age the history of orienteering. This website may help you: http://orienteering.org/about-the-iof/history/

6. What is sportsmanship? Create a display poster to explain what it is. Remember to show the different qualities a good sportsperson should display. Create your poster for children who are the same age as you.
