8GH The Rock Cycle and weathering

Sedimentary rocks What are the three types of weathering? How can rock particles be moved in erosion? What happens to the particles when they reach the sea? How do sedimentary rocks form?

Hi my name is Rocky!!

Split the cards into 2 groups

Oh no! I'm breaking up... Rocks are broken up into smaller pieces, this is called weathering. There are three types. 1. Physical weathering 2. Chemical weathering 3. Biological weathering

I'm being swept off my feet! The particles now move by erosion. There are four major ways erosion can occur: 1. By gravity 2. By water 3. By wind 4. By ice

I've got a sinking feeling... When the particles reach the sea they sink, this process is called deposition. During deposition particles of rock are laid down in layers.

Oh no, what's happening now? This might not be so bad after all - I'm feeling whole again. As the layers of sediment build up, the pressure on the lower layers increases and water is squeezed out. This process is called compaction. At the same time the particles of sediment begin to stick to each other - they are cemented together by clay, or by minerals.

Sedimentary rocks 2 Name 4 sedimentary rocks. What are the characteristics of sedimentary rocks?

Sedimentary rocks 1. Are formed from layers of sediment built up over many years. 2. Are grains of sediment cemented together by various minerals. 3. May contain fossils - remains of plants and animals that were caught up in the sediment. Examples are Coal, Sandstone, Conglomerate, Chalk, Limestone, Slate

Metamorphic rocks How do metamorphic rocks form? Name some examples of metamorphic rocks and the rocks they are made from.

The pressure's mounting... I'm getting all hot under the collar now that the pressure is on. Deep in the Earth's crust rocks can be put under huge pressures and temperatures are very high. This can cause the minerals in the rock to change. This process is called metamorphism. Limestone can change into marble, shale and mudstones into slate, and igneous rocks like granite can turn into gneiss. Now that I am a metamorphic rock I've had to make a few changes. What now? Oh dear, not another a choice!

Igneous rocks How do igneous rocks form? What are the 2 types of igneous rocks? What are the differences between the 2 types?

It can get quite hot deep in the Earth's crust. In fact, it can get so hot that the rocks that make up the crust can actually begin to melt. This is called magma. It tends to move upwards through the crust. It's getting very hot down here! Oh no - I'm melting, I'm melting...

I'm cooling down... But I think I'll take my time about it... When the magma cools and solidifies in the earch’s crust it forms intrusive igneous rocks. They: 1. Have large crystals - magma cools very slowly 2. Are made up of interlocking crystals. Brrrrrr…

When magma comes to the Earth's surface in a volcanic eruption. This process is called extrusion which makes extrusive igneous rocks. Basalt and pumice are extrusive igneous rocks. Generally extrusive igneous rocks: 1. Have fine Crystals - magma cools very quickly 2. May contain gas bubbles. This is my chance... I'm free!

Up, up and away... What - light at the end of the tunnel? Just like sedimentary rocks, metamorphic rocks can be forced to the Earth's surface too. Movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift.

The choc cycle In this class you will be using chocolate as a model for the rock cycle. This will be assessed for AF1 (Thinking Scientifically)
