Hello,
Chemical weathering can be considered by the "rusting of rock".
Weathering can be described of the breaking down of rocks and other materials on the Earth's surface. There are three types of weathering: mechanical, chemical, and biological. Mechanical weathering is the type of weathering in which rock is physically broken into smaller pieces. Chemical weathering is the type of weathering in which chemical changes break down rock. Biological weathering is the type of weathering in which animal, plant, and microbes means weaken and or disintegrate rock.

Answer:
300
Explanation:
We want to estimate the population of 1000m2 but in our sample of 100m2 we found 30 organism and we know that there are ten 100m2 in 1000m2 meaning there is an estimate population of 300 resulting from 30 per 100m2 sample X 10 [which is the total number of 100m2 in 1000m2].
I believe the answer is C. E. And F.
