Definition:
Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material.
There are 3 types of weathering:
a)physical
b)chemical
c)biological
•Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
•Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
•Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock.

Explanation:
We all have a vague idea of what an animal is. However, when we ask for defining characteristics, there may be confusion. Saying that an animal is moving, for example, may be true for some groups, but not for others.
For an organism to be considered an animal, it must have characteristics in common with all animals, that is, that organism must be eukaryotic, multicellular, heterotrophic and have no cell wall, muscle and nerve cells.
<h3>Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.</h3>
