Rock ID
A dark, fine grained rock commonly found in lava flows
Basalt
The process of layers of sediment being pressed together over time is called this
igenous rocks that cool quickly at the surface and have small crystals are called
extrusive igneous
pieces of rock transported by water, wind or ice are called this
sediment
A light colored, course grained igneous rock with large crystals that is often used for countertops
granite
The type of sedimentary rock that forms from the buildup of plant or animal remains (like coal or limestone)
organic sedimentary rock
Holes in extrusive igneous rocks indicate that there was what in the lava or eruption?
There was a high concentration of volcanic gases.
if rock melts then cools, it becomes this type of rock
igneous
A chemical sedimentary rock that you might eat a lot of
This type of sedimentary rock forms when minerals dissolve into water and it becomes so concentrated that those minerals crystalize out of the water
chemical sedimentary rock
Name three examples of igneous rocks (try to choose ones we have looked at/talked about in class)
Obsidian, pumice, scoria, basalt ect.
how can you turn a metamorphic rock into an igneous rock
melting
A rock made mostly of calcite which comes from the shells of dead marine organisms and often contains fossils
limestone
What features do scientists look for to identify clastic sedimentary rocks, and how does each feature help determine the rock’s formation?
Grain size/Clast size and shape and composition
