This type of rock forms from volcanic magma.
Igneous Rock
This type of rock forms from sediment left on the bottom of a lake.
Sedimentary rock
This type of rock is formed by reheating it or applying huge pressure to it.
Metamorphic rock
Sandstone is a type of this rock
Sedimentary rock

Extrusive
Rocks formed deep underground from magma are called what type of rock?
Intrusive
Fossils can be found in what type of rock only?

Weathering is when
rocks, minerals or other parts of Earth’s crust break into smaller pieces.
Weathering is super
strong and can break even the toughest rocks and stones.
Erosion is when
the small pieces of earth are picked up by water and wind and moved to a new place.
A dust storm is erosion.
It moves millions of tiny pieces of earth to a new place.
Wave Rock in Western Australia was formed by erosion.
It is 15 metres high and took over 2 500 years to create.
Deposition is when
the tiny pieces of earth that have been moved are put in their new location.
Which statement is correct?
Weathering, erosion and deposition happen everyday. Sometimes we can see it, sometimes we can’t. Think of the sand at the beach. Sand is made by waves hitting rocks and breaking off tiny pieces. This is weathering. Erosion is when the tide pulls the sand towards the water. Deposition is when the sand stops moving and stays in its new location.
Murphy's haystack has been weathered by
the wind
The wave rocks of Western Australia were weathered by
wind and water
