Compare and contrast the two kinds of chemical bonds (ionic and covalent)
attashe74 [19]
An Ionic bond is when you have a metal and a nonmetal element bonded together. In this kind of bonds, the metal atom takes electrons from the nonmetal. on other words, this bond involves the gaining and losing of electrons. The atom that receives the electrons becomes an anion (negatively charged ion) and the one that loses them becomes the cation (positively charged ion)

A covalent bond is a bond created between two nonmetals element. In here, both atoms share the electrons.

Both bonds involve interaction between atoms.

Sea level changes occur at a rate of 10 m per 1,000 years. Regional erosion occurs at a rate of 2 m per 1,000 years. Uplift occu
PtichkaEL [24]
<h3>Answer:</h3>

The rate of sea level change is the fastest

<h3>Explanation:</h3>

To determine the process which is the fastest we need to determine the rate at which each occurs in meters per year.

Rate of sea level changes is 10 m per 1,000 years

Therefore, the rate of sea level change = 10 m ÷ 1000 years

                                                                 = 0.01 m/yr

Regional erosion occurs at 2 m per 1,000 years

Therefore, Rate in meters per seconds = 2 m ÷ 1,000 years

                                                                 = 0.002 m/year

Uplift occurs at a rate of 0.1 m per 1,000 years

Thus, rate in meters per seconds = 0.1 m ÷ 1,000 years

                                                       = 0.0001 m/yr

Therefore, the rate of sea level change is the fastest at a rate of 0.01 meter/year
