Meta talks about how igneous rocks form.
|
|
|
|
| | |
| Yes, people have sandstone floors because they tend to be very strong. Now, onto igneous rocks. | |
| | |
|
 |
| | |
| Oh! I know this! Igneous rocks are formed when rocks go through heat and pressure, right? | |
| | |
|

|
| | |
| No, you're talking about Metamorphic rock. Igneous is formed from magma or lava cooling, into either intrusive or extrusive. | |
| | |
|
 |
| | |
| Wait, I think I'm catching on. Extrusive is outside the Earth, and intrusive is in the Earth, right? | |
