Which describes a climate effect on the rate of weathering? Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature.

Answers

Answer:

the answer is Cold climates favor mechanical weathering.

Explanation:

I got 100% on the Quiz

Statement that describes climate effect on the rate of weathering as regards this question is A:Cold climates favor mechanical weathering.

Weathering can be regarded as disaggregation of rocks into smaller bits by the actions of agents of weathering such as man, animals, water and so on.

However, climate can also have effect on the rate of weathering, when there is cold climate, mechanical weathering is favoured.

Option B,C,D are wrong because high temperature brings about increase in rate of chemical weathering.

Therefore, option A is correct.

5. Which type of substances do you separate into lons when writing the complete lonic equation?

Answers

Answer:

As a general rule, soluble ionic compounds, strong acids, and strong bases should be written as dissociated ions in the complete ionic equation. Insoluble salts and weak acids are written using the neutral molecular formula since they only dissociate to a very small extent in water.
