Explain the difference between chemical and physical weathering. (1 point)

Give one example of chemical weathering and one example of physical weathering. (2 points)

The difference between chemical and physical weathering is that physical weathering does not change the molecular structure of the rock.

An example of chemical weathering is limestone where it is dissolved by water and the ions are carried away.

An example of physical weathering is when water freezes inside of cracks in rocks. The water expands which causes the rocks to split apart.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
