Science- rocks and the earth

The breaking of rocks into smaller pieces and their movement away from their original rock

Chemical weathering is when acid breaks up rock

Biological weathering that happens when plants and animals break up rock

Erosion is the process where rocks are broken down by natural forces such as wind or water

occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

A porous material has small gaps that may contain substances in their liquid or gas states. Water can soak into a pororus material

The settling of sediments that have moved away from their original rock

The model where the sun is in the centre of the solar system

The model where the Earth is at the centre of the solar system

Ceramic materials are compounds. They include metal silicates, metal oxides, metal carbides, and metal nitrides.

The distance light travels in a year

weight of sediments above squeeze them into rocks

another substance sticks the sediment together

Liquid rock underground- cools slowly and forms large crystal

Liquid rock above ground- cools quickly and forms small crystals

continuous physical force exerted on or against an object

Any process that moves earth’s surface to a higher elevation

Exoplanet!

Light-year is the distance light travels in one year.
