Geography Homework Help!

Question

Okay I need some help with my geography homework...

I need to answer the following questions...

We're doing coasts and beaches, etc.

1. Why aren't big waves formed on lakes?

2. What are some of the causes of waves?

3. Why are some waves bigger than others?

4. When ____________ blows over the ____________, _______________ is transferred from the wind to the ____________________ waves _____________ energy.

5. Describe the movement of an object such as a boat or a surfboard, as waves go past them.

6. Waves travel a long way across the ocean before they reach land. Why do waves break as they approach a beach?

7. The water which rushes towards the shore when waves break must flow out again. Often the rush of water back out to sea scours a deep channel in the sand. This is called a rip.

a) Why should you be careful of rips?

b) What can you do if you get caught in a rip?

c) How can you spot a rip?

d) How can rips be used by surfers?

8. If you had to swim ashore from a sinking ship on to rocks, would you choose to swim to a place where rocks were vertical into deep water, or sloping into shallow water? Why?

If any of you could answer just one, or even all if you know the answers, I would greatly appreciate it. 10 points to the person who gives me the most answers. I will be choosing that person in an hour.

Thank-you in advance.

Answer 1

1. not enough area for the wind to create big waves

2. wind, underwater earthquakes, meteroites

3. more energy, constructive interference with other waves

4. wind,water,energy,surface,transfer

5. circle

6. they drag on the sea floor reducing wavelength and increasing amplitude causing an unstable situation and the wave breaks

7. they can drag you out to sea, swim parallel to the beach until out of the rip, look for water rushing away from the beach..or screaming swimmers;) surfers use rips to get out to where the waves are

8. ??? verticle less violent waves???
