Metamorphic rocks are created from the earth`s plate movement because when the plate moves around and causes heat it makes metamorphic rocks

Igneous rocks form when molten rock cools and hardens either deep underground or on the surface.

Sedimentry rocks on earths surface from erosion

How many different rocks? 1.metamorphic rocks 2.Igneous 3.sedimentry

Volcanos / bolders / surface erosion The earths crust moves constantly , rocks break and plates lurch to new position. Rocks falling will cause rocks to break.

Pebbles / wind / ice Pebbles come from broken rocks or eroded rocks. Wind plays in earths surface it causes earth`s object erode. When ice melts it turns to water and makes oceans bigger for sea creatures.

What activities (non human) will cause rocks to break ??? Weathering Erosion Ocean water

Erosion The process of erosion is when wind carries one thing to another it takes a long time to dissapear!
