What would happen to the oceans if continental and oceanic crust had the same density?

Biology
1 answer:
levacccp [35]3 years ago
4 0

Answer:

The oceanic crust is formed by partial melting of the mantle at mid-ocean ridges. The continental crust is formed even more cycles of partial melting over time, resulting less dense rocks.

Explanation:

The mantle, oceanic crust, and continental crust all have different compositions due to a process called partial melting.

This is where you start to melt a rock, but don´t melt it all the way.

When you partially melt a rock, certain chemical elements tend to stay in the solid rock while others tend to go into the melted part.

As a result, the rock that forms from that melt is less dense than the original rock.

If you then partially melt that rock, you get a rock that is even lighter.

How can islands be created by plate tectonics
Tema [17]
One example is the country of Iceland which is a large island right on the mid-Atlantic ridge which is where the Atlantic oceanic plate is rifted in two and where the underlying magma wells up to the surface as the two sides to the plate move opposite to each other. The resulting volcanic rock then builds itself up into an island.

Sedbober [7]

Answer:

1. Glycerol

2. Fatty acids

3. Monoglycerides

4. Triglycerides

5. Hydrocarbon

6. Hydrophobic

Explanation:

1. Glycerol

Fat consist of a molecule called glycerol that is attached to one, two, or three fatty acids. Glycerol is the basis of all fats and consists of a three-carbon chain that is attached to the fatty acids.

2. Fatty acids

Fats is made up of three fatty acids and a glycerol, it can also be called triacylglycerols or triglycerides.

3. Monoglyceride

It is a glycerol molecule with a singular fatty acid. It is formed through the combination of OH of glycerol to the OH of the fatty acid.

4. Triglycerides

It has three fatty acid molecules. It is a tri-esters made up of a glycerol attached to three fatty acid molecules.

5. Hydrocarbon

Fatty acids is made up of long, unbranched hydrocarbons with a carboxylic acid group found at one end.

6. Hydrophobic

The hydrophobic nature of fat arises from the carbon-hydrogen bonds that are nonpolar.
