Answer:

Your question is somewhat incomplete or is not well written, but even so, according to what is understood, it could tell you that the erosion of the surfaces affects with the increase of the vegetation of the surface.

Explanation:

The plants when growing on eroded surfaces, or that suffered erosion, what they do is retain the eroded particulates and accumulate them, thus generating an increase in mounds.

A very clear example of this is the presence of sand dunes on the beaches that present vegetation, these sand dunes or dunes develop since the eroded sand particles are retained by the roots of the vegetation and slowing down the cycle of erosion.

How could an increase in industrial activity in developing nations contribute to global climate change?

netineya [11]

If there is an increase in industrial activity, that means that more heat will be dissipated to the atmosphere in the form of carbon dioxide. Industrialization requires fuel to keep the processes on the go. At the end of the pipeline, the combustion of fuel would result to carbon dioxide released to the atmosphere. That's how it is contributing to the global climate change through the greenhouse effect.

A standard backpack is approximately 30cm x 30cm x 40cm. Suppose you find a hoard of pure gold while treasure hunting in the wil

Blizzard [7]

Explanation:

The dimensions of a standard backpack is 30cm x 30cm x 40cm

The mass of an average student is 70 kg

We know that, the density of gold is 19.3 g/cm³.

Let m be the mass of the backpack. So,

$\text{density}=\dfrac{\text{mass}}{\text{volume}}\\\\m=d\times V\\\\m=19.3\ g/cm^3\times (30\times 30\times 40)\ cm^3\\\\m=694800\ g\\\\\text{or}\\\\m=694.8\ kg\approx 700\ kg$

An average student has a mass of 70 kg. If we compare the mass of student and mass of backpack, we find that the backpack is 10 times of the mass of the student.
