What is the name for plant and animal remains preserved in rocks over millions of years?
That would be a fossil.
What rocks change from one type to another over millions of years?
Sedimentary rocks can change into metamorphic rocks through heat and pressure over millions of years. Metamorphic rocks can then undergo further changes to become igneous rocks through melting and solidification. This rock cycle is a continuous process that occurs over vast timescales.
How long does it take for each type of rock to form?
Igneous rocks can form quickly in days to months from cooling magma, sedimentary rocks can take hundreds to millions of years from weathering and deposition of sediments, and metamorphic rocks can form over millions of years from existing rocks under high heat and pressure.
How many years does it take for a rock to change?
The time it takes for a rock to change can vary widely depending on the type of rock and the geological processes involved. For example, sedimentary rocks can form over millions of years through the accumulation of sediments, while igneous rocks may change through volcanic activity within a matter of days to years. Metamorphic rocks can take thousands to millions of years to transform under heat and pressure. Ultimately, rock changes occur over geological timescales, often spanning millions of years.
What happens to sediments after a million years?
After a million years, sediments can undergo diagenesis, which includes compaction and cementation. This process transforms loose sediments into solid rocks like sandstone, shale, or limestone. Over time, these rocks may be uplifted and exposed at the Earth's surface by tectonic forces.
How are rocks changed?
Erosion and weathering over millions of years

What happens to rocks above earths surface over the years?
Rocks get eaten away by weathering and erosion

How are rocks organized?
forms from dead plants and animals that compress deep in the Earth's crust over millions of years.
How long does it take for each type of rock to form?
Igneous rocks can form quickly in days to months from cooling magma, sedimentary rocks can take hundreds to millions of years from weathering and deposition of sediments, and metamorphic rocks can form over millions of years from existing rocks under high heat and pressure.
Why rocks are found in layers?
they are found in layers because over the millions of years they have formed over the top of each other and eventually formed a rock
The process that build up sediment over millions of years is?
The process that builds up sediment over millions of years is called sedimentation. It involves the accumulation of weathered rocks, minerals, and organic material that settle in layers on the Earth's surface. Over time, these layers of sediment can become compressed and cemented together to form sedimentary rocks.

Where did the beach come from?
The beach is a result of millions of years of erosion by the sea. Millions of years ago rocks were in the place of the sand, but the ocean over time broke away little pieces. Eventually all the rocks were gone, and sand stayed in their place. This is why beaches/shores only occur near water.
What is the changing of rocks over time called?
The changing of rocks over time is called the rock cycle. It involves processes such as weathering, erosion, deposition, compaction, and cementation that transform rocks from one type to another. This cycle is driven by geological forces and occurs over millions of years.
