Tide Direction

You can tell I've got too much time on my hands


Geography – Year 9 – Friday Afternoon - Cannock

Gentlemen, today we shall be looking at the North Yorkshire Coast and what has happened to it over the last 2000 years and what’s likely to happen to it in the future.

Sir

Yes Smith?

I’ve never seen the sea.

Hands up those who have never been to the seaside (10 raise hands – sea is 70 miles away)

You who have seen the sea…………..where?

Benidorm…..Magaluf……..somewhere hot Sir………. Rhyl…..(looks of incredulity)

Oh God……………….

OK, 2000 years ago the coast of Yorkshire was about 10 miles further out to sea than it is today.

How do you know Sir?

Because we have found evidence of Roman settlements out in the sea and the coastline keeps getting washed away, even today.

Is it the sea, coming in and bashing the shore that washes it away Sir?

Well, yes and no, Tompkinson. The sea doesn’t actually come in…it goes up and down but it does bash against the shore.

So Sir, the waves come in but the tide goes up and down…………why don’t the waves go up and down like the tide?

Well because the waves are sort of directed by the wind but whatever the direction of the wind the tide still goes up and down. Yes Potter?

So the waves come in and the tide goes up and down………….so where has half of Yorkshire gone?

Ah well…now we’re getting somewhere…….most of the top of Yorkshire was carried from the north by ice and dumped at the seaside.

Sir? How can ice carry anything?

Saints preserve us!!!!!!! Ice is an agent of transportation and about 10.000 years ago ice brought boulder clay to Yorkshire.

Sir?

Smithers?

We use clay in Art and when we throw it up on the ceiling it sticks. When we make those crappy mugs with it it’s rock hard. How come it wears away?

Sir?

Taylor?

We’ve got ice on our street at the moment but it’s not an agent of transportation.

That’s because it’s not heavy enough – ice moves as a result of its own weight.

Isn’t that fatism Sir? You could get reported.

Shut up Lewis… ice moves because it is so heavy – like in the glaciers of the Andes and Himalayas.

What’s a glacier Sir?

It’s a river of ice that slowly creeps down a valley.

How fast does it creep Sir?

Well, in the 1950’s this plane took off from somewhere in South America and flew so high it encountered the Jet Stream

Is that for jets only?

Shut up Green………… the jet stream is a powerful wind that made the plane late arriving in Santiago……..so late it wasn’t seen for 30 years. Yes Williams?

How can planes fly in streams……you did say streams didn’t you?

YES………….but air streams not water type streams. Anyway this plane appeared from the glacier snout………….WHAT Bullock?

My dad has a pig with a snout – it craps all over the garden

30 minute detention Bullock…………….moving on. The tide and the wind have formed and destroyed the Yorkshire Coast. Any more questions?

Sir?

Wilson?

What causes the tide to go up and down and/or in and out?

Good point Wilson….it’s the moon pulling the water towards it (and a bit of the sun). Where it pulls the hardest it’s high tide. When it takes a rest it’s low tide.

So Sir you’re saying the man in the moon is responsible for pulling the tides?

That’s right Boyd and if you remember that you’ll pass your GCSE

Sir – what if I mention that my dad used to go to the Man in the Moon in the 70’s and used to pull loads of things ……..will I get extra marks?
