Post your answers below for any of the sections

Water on land - label sketch diagram of meander - river cliff, slip off slope, erosion, deposition, thalweg (fastest flow), oxbow lake??
Restless earth - explain tsunami using case study - Tohoku, Pacific plate and North American plate, build up pressure, pressure released resulting in a upwards flick that displaces water above it, creates tsunami

I put the same as you for Restless Earth :biggrin:

but I don't do Water on land

Restless Earth
what is a plate margin? a plate margin is a boundary between plates
outline the differences between constructive and destructive plate margins? constructive waves are when plates move away from each other and magma rises from the mantle. destructive waves are when the oceanic plate subducts under continental forming an ocean trench.
what problems do volcanoes create? (the question was along these lines)
Ash so air travel disruption
gas emitted harm environment
visibility problems
causes infertile land so difficult to grow crops
damages local habitats.
how do you predict and monitor volcanoes?
monitor by measuring seismic waves in the mantle and seeing if there are any changes
monitor by using a camera to detect lava activity
predict by estimating its eruption due date

Wow. I had almost identical answers to you.

how do you predict and monitor volcanoes?
I added tilt-meter to measure small changes and seismometer which can give an indication of the rising magma beneath the volcano

Glad to hear that! what do you think you got?

Hopefully 60 or 60+
But I think I messed up on some questions in coastal zones. So I probably won't get what I hoped.

I'm just hoping for an A*.

If i get less than a D whT do i get? Also if i got an A* or A in controlled assessment and paper 2, with the D what do you think it will total out to?

What about temperature change is that a way to predict volcano

If you get A* in both your controlled assessment and paper 2 along with a high D. Then you can get a mid B.
But I am not too sure about these predictions

What do you mean by 'both' controllef assessments, i only did 1? Thank you!

I meant to say if you get A* in your controlled assessment and paper 2 - human geography. But these predictions are not accurate and will most likely change

is that all the questions on restless earth ?

There were 2 more.
1. Describe the figure and the link between tsunamis and earthquake (something like that) (2marks)
2. Use a case study to show explain how a tsunami forms (3marks)
