How do river deltas change over time?
More and more sediments build up around the delta from deposition
Water erosion wears away land and rocks turn to pebbles.
Smaller rivers disappear and the sediments is not deposited
Fewer sediments are deposited in to the river.

A wide valley
A deep ocean
A lava flow
A mountain range

heat from inside the Earth melting rocks
the dropping off of sediment
What caused this sea arch to form?
Wind and ice hit the rock and wore it away
Ocean waves hit the rock and broke off pieces
Glacier movement wore it down
Deposition of sediment caused it to break down.
