The Rock cycle

What are the three types of rocks?

• Mountain, sedimentary, and sand

• Igneous, Rock, Metamorphic

• Igneous, Sedimentary, and Metamorphic

• What was the question?

How does a Igneous rock form?

• From melted material

• From other rocks

• From mountains

• From magama

What is the difference between lava and magma?

• There isn't

• Magma is when it's in the volcano and lava is when it is out of the volcano

• Lava is when it's in the volcano and magma is when it is out of the volcano

• The magma is hot and the lava is cold

Where are intrusive and extrusive igneous rocks made?

• Intrusive rocks are formed at the crust's surface and Extrusive rocks are formed on the earths crust

• There're both formed on the earths surface

• They are made at the top of a volcano

• Extrusive rocks are formed at the crust's surface and Intrusive rocks are formed on the earths crust

Why are fossils only found in sedimentary rocks?

• Because sedimentary rocks form at temperatures and pressures that do not destroy fossil remnants

• Because Igneous rocks form at temperatures and pressures that do not destroy fossil remnants

• Because of the different kinds of rocks already in the sedimentary rocks

• Because the fossil just stick to sedimentary rocks and they like the feel of the sedimentary so they stay there

How do mountains form?

• By the ground moving upward

• Because of the subduction

• Because of the movement of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains

• Because volcano's... wait oh we're talking about mountains. Sorry don't know, can't help you with that.

What is subduction?

• When the tectonic plates take over the world!

• The movement of the tectonic plates when they colliade

• I really don't know and I really don't care either

• The movement of the edge of a plate of the earth's crust into the mantle beneath another plate.

How do volcano's form?

• By mountains

• When magma from within the Earth's upper mantle works its way to the surface

• When the mountains think I want to be a volcano and then they become one

• When the gases all mix together to create a mountain then the magma from below the earth sees the mountain and starts putting magma into it and it starts to flow out lava, Very simple! :D

True or False: Continental plates are more dense than Oceanic plates.

• True

• False

During subduction, which plate will usually go under, the oceanic or continental plate?

• Oceanic

• Continental
