There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
Answer:
22.94
Step-by-step explanation:
3.7x6.2
multiply the values
This has to be 20 characters long so I’m just saying stuff but it’s 1500
This is a multiplication equation. So to solve for y, we must divide.
6.3/0.9 = 7
y = 7
Answer:
20
Step-by-step explanation:
This is the Greatest Common Factor (GCF) of 40 and 100:-
40 = 2 * 2 * 2 * 5
100 = 2 * 2 * 5 * 5
Gathering the duplicates, GCF = 2 * 2 * 5 = 20
Answer is 20
