In what layer does plasticity and convection occur?

Mantle.

Explanation:

The mantle is present between the earth's crust and the core. It is not a static layer. The upper part of the mantle is called the asthenosphere which changes its shape with temperature and pressure. It is not a rigid layer. Any changes in the inner layer of the mantle cause the movements in asthenosphere plates. This is called the plasticity of the mantle. The convection is a process, where high temperature causes the movement of atoms. The atoms move from high-temperature region to the low-temperature region and thus a cyclic movement happens in the inner mantle. This causes the changes in the plates location of the upper mantle.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
