describe the processes taking place in isostatic change.
1) during an ice age, the weight of the ice causes the land to sink.
2) when the ice age ends the ice melts causing the land to rebound up like a spring.
3 of 10
large glaciers and ice sheets are the products of the last glacial maximum. What is another physical factor that changed?
The sea levels fell because much of the hydrosphere was locked in ice.
4 of 10
what is tectonic change?
when the land rises or sinks at the boundaries where the tectonic plates meet.
5 of 10
Describe the processes involved during Eustatic change.
1) water is stored in the form of ice during an ice age
2) this causes the sea level to fall
3) as the world moves out of an ice age, the ice melts, causing the sea levels to rise again.
6 of 10
What is the definition of Eustatic change?
the rising and falling of sea levels influenced by ice ages.

Stable
8 of 10
Outline the processes involved during tectonic change.
1) a tectonic plate moves
2) this can cause the sea bed to rise or fall
3) this then causes the sea level to rise or fall.
