Rivers are important causes of geological change. They move particles of old
rocks with small crystals.
_______ and deposit them in the sea. The process of laying down new layers of
sediment is called ________________. As the weight of the new sediment
Volcanoes are common on tectonic plate
increases, the layers below are ______________. Fast flowing water can move
boundaries. What other natural events
________ stones but when the water slows down, the stones ______. Sediments
would you expect to occur at these
form in layers called _______, the oldest at the base. The particles become finer
boundaries?
the __________ out to sea it is.
The Rock Cycle. Draw a suitable diagram in each box to illustrate the caption.
Exposed rocks are weathered until they
break into smaller pieces.
The pieces are transported in a river and
deposited in the sea to form sedimentary rock.
Sedimentary rocks are heated and exposed to
pressure and change into metamorphic rocks.
More heating causes the metamorphic rock to
melt. It solidifies to form an igneous rock
(often exposed on the surface)
