# Weathering Rocks on the surface of the Earth can be worn away by rain, moving water or wind, or in other ways. - Weathering changes the shape of the rock and makes lots of smaller pieces. - Plant roots can break rock into smaller pieces too. - When water in a small crack changes to ice it takes up more space. - Now the small crack is a bigger crack. # Topic 4 | Rocks and Soils - This mushroom-shaped rock is formed from sandstone. - This rock has been worn away. - This rock is softer than the top so has worn away faster. - Waves from the sea, and wind, have made this arch of rock. - This is made from the metamorphic rocks slate and quartzite. - Can you see layers of rock? ## Key words - worn - weathering - crack - waves - sea - arch - quartzite - shale ## Changes - shale, a sedimentary rock changes into slate - sandstone, a sedimentary rock changes into quartzite
