About Tsunamis

Hi all,

Here I am with another link and questions about it to help with your listening and vocabulary. I hope there won't be a problem with it as it comes from National Geographic originally and doesn't appear on their site now which I think is a shame as it's interesting and has nice graphics.

It's loooong!!!!


As it is so long, I decided to break it up for you so you can go off for a coffee (see, that is why the coffee bit is in my blog domain name!) and come back to it when you feel refreshed! I have also started the vocabulary and questions from 3.50 as the first bit is just the introduction and although a very good one, is not going to challenge you enough!

Part A starts at 3.50 and as usual,  I have put some vocabulary up first for you to check out in a dictionary if you don't know it already. Part B starts at 6.03. -->

Part A (3.50)

To trigger something	To sweep onto
To shift	To engulf
A landslide	To near
To be thrust up	To brake
The body of water	onshore
The ripples

 Here is the link: About Tsunamis
Watch the clip up to about 6.03 then stop it. Now try to answer Part A questions. Keep going back over it if you have forgotton stuff.
  -->

How is an ocean wave caused ?

What 3 things can cause a tsunami and what makes it so different from an ordinary wave ?

Exactly what happens to the ocean bed when an earthquake cracks the ocean floor ?

What is the effect of this on the water above it ?

Describe the height and length of a tsunami.

What 3 things happen as it reaches land ?

How is the wave described ?

Does it break onshore ? If not, what does it do ?

 
Now either go and have a coffee....or not....then start Part B with the next set of vocabulary. 
  -->

Part B (6.03)

A slab	Saw-tooth
Sheer	To loom
A geological fault	A spring
Sharp

 
When you are ready, start watching again and at the end, try to answer Part B questions. 

-->

Why was it of interest to scientists ?

What was below the ship ?

How have these been formed and over how many years ?

What did they find first ?

What did they discover next ?

What did this give evidence of ?
