decomposition of rock when exposed to acidic plants

Answer 1

The best example of chemical weathering from the options provided is:

decomposition of rock when exposed to acidic plants.

Chemical weathering involves the alteration of the chemical structure of rocks and minerals, and acidic plants can contribute to this process by breaking down minerals in the rock.

Answer 2

Which of the following indicates that different rocks in the same area might weather differently? Select the two correct answers. (1 point)
Responses

a smooth plain

rock deep in a cavern

Answer 3

The two correct answers that indicate that different rocks in the same area might weather differently are:

1. rock pillars in the middle of grassy plains
2. cliffs with ridges

These features suggest variations in the weathering processes and resistance of different rock types in the same area, leading to distinct formations.

Answer 4

How does time affect the physical weathering of a rock?(1 point)
Responses

Over time, the rock will become flat, slowing the rate of physical weathering.

Time does not affect physical weathering, only chemical weathering.
Time does not affect physical weathering, only chemical weathering.

The longer the rock has been exposed, the more it has weathered.
The longer the rock has been exposed, the more it has weathered.

Rock weathers the most when first exposed, then more slowly.

Answer 5

The correct response is:

The longer the rock has been exposed, the more it has weathered.

This statement reflects the general principle that exposure to weathering agents (such as wind, water, and temperature changes) over time will result in increased physical weathering of the rock.
