WEATHERING AND EROSION with the ROCK CYCLE

How are igneous rocks formed?

• Formed when lava or magma cools (crystalization)
• formed when sediments go through cementation

• formed when different rocks underground go through heat and presure

• formed by the glacier dropping rocks and hitting against mountains

How are metamorphic rocks formed?

• formed when ice morphs into rock and melts into lava

• Formed when lava or magma cools (crystalization)

• formed when sediments go through cementation or compaction

• Formed when other rocks underground go through heat and pressure and end up as metamorphic

How are sedimentary rocks formed?

• formed when sediments that broke of other rocks and go through cementation or compaction and turm into sedimentary rocks
• formed when lava or magma cools (crysilization)

• Formed when other rocks underground go through heat and pressure and end up as metamorphic

• formed when sediments are found underwater

What is weathering?

• the process of wearing down rocks and transporting it

• the relocation of rocks

• when the weather is bad

• The process of breaking down rocks

What is deposition

• The dropping of sediments or rocks after erosion

• the process of breaking down sediment

• when rocks are being weared down and transported.

• a deposit at the bank

What is Erosion

• The wearing down and relocation of sediments and rocks

• the dropping of sediments and rocks

• the process of breaking down rocks

• the movement of the government
