How can you distinguish a sill from a buried lava flow?
These extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain
Does diamonds and table salt have anything in common?
yes they do have something in common they both have microscopic crystals in side them
Why do rocks formed from lava have small crystals?
That's because of the cooling speed. When a magma or a lava cools, it forms crystals. The longer these crystals have the time to form, the larger they will be. However, at the surface, the lava cools relatively fast (at least, compared to magma that stays inside the earth). The crystals in the rock that forms that way don't have a lot of time to form, so don't grow big.
How do you know a mineral's streak?
The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.
What is a fracture of earths crust?
A fault is a crack or fracture in the earth's crust. In geology, a fault or fault line is a planar fracture in rock in which the rock on one side of the fracture has moved with respect to the rock on the other side. Large faults within the Earth's crust are the result of differential or shear motion and active fault zones are the causal locations of most earthquakes. Earthquakes are caused by energy release during rapid slippage along a fault. A fault that runs along the boundary between two tectonic plates is called a transform fault.
