The different landforms like dunes and deltas are formed from which process?
deposition- the settling of sediment
Igneous rocks are formed when lava and magma cool. Name two Igneous Rocks.

What is the difference between weathering, erosion and deposition?
what is, weathering breaks rock down, erosion carries it away and deposition drops the sediment off?
How can I get a metamorphic rock from a sedimentary rock?

What are weathering and eroding?
Fossils are found in which rock
Sedimentary
The oldest rocks on earth are found in which layers
What are the bottom ones?
A sedimentary rock can change into igneous rock by
Melting and cooling
This type of sedimentary rocks form when dead plants from millions of years ago mineralizes. We use it to heat homes
