Question

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 occurs at a rate of 0.1 m per 1,000 years. Which process is the slowest?

Answer 1

Sea Level changes or uplift, one of them

Hope this suites your question.

(sorry for putting my answer so late)

Answer 2

Uplift rate.

Explanation:

We have been given that 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 occurs at a rate of 0.1 m per 1,000 years. We are asked to choose the slowest process.

Let us find each rate in terms of per year as shown below:

`\text{Sea level change rate}=\frac{10\text{ m}}{\text{1000 years}}`

`\text{Sea level change rate}=\frac{0.01\text{ m}}{\text{ year}}`

`\text{Regional erosion rate}=\frac{2\text{ m}}{\text{1000 years}}`

`\text{Regional erosion rate}=\frac{0.002\text{ m}}{\text{year}}`

`\text{Uplift rate}=\frac{0.1\text{ m}}{\text{1000 years}}`

`\text{Uplift rate}=\frac{0.0001\text{ m}}{\text{year}}`

Therefore, uplift rate is the slowest process as uplift occurs 0.0001 meter per year.
