I would say that in very fast moving water such as in a river, the cobble size could be transported because cobbles are 64-256mm so are quite big and in a quiescent stream won't move much but in a freshet say in a steep mountain stream they can be rolled along such as I observed in the local streams at a mining town during the Hurricane Fifi in Honduras in 1974.
Answer:
B =48
Explanation:
To solve this problem we need to know that ALWAYS the sum of complementary angles are equeal to 90.
If A is complementary to angle B, we can affirm that:
A+B=90.
Given that A=42, solving for B:
B = 90 - A = 90 - 42 = 48
Then, the measure of angle B is 48.
Irdk but that is a very good question
They erode the earth, carrying along minerals and soils. When they melt, they deposit these materials, creating other landforms.
