Mechanical weathering provides fresh surfaces for attack by chemical processes, and chemical weathering weakens the rock so that it is more susceptible to mechanical weathering.
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
Weathering is the breaking down of rocks into smaller pieces, erosion is the movement of these sediments from one place to another by wind, water, or ice, and deposition is the settling of these sediments in a new location. Weathering and erosion work together to shape the Earth's surface, while deposition adds new sediment to create landforms like beaches, deltas, and sand dunes.
Factors: Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc. Weathering, on the other hand is caused by contact with the earth's atmosphere. These atmospheric conditions may be heat, pressure etc. Movement: Erosion is caused by the movement of eroding agents while in weathering there is no movement. Weathering is caused when rocks come in contact with atmospheric conditions but there is no movement involved of either of the components.
Students can compare and contrast Earth's sections by examining differences and similarities in composition, characteristics, and processes. For example, they could compare the solid crust to the liquid outer core in terms of state of matter and behavior. By exploring variations in temperature, pressure, and density in different sections, students can gain a deeper understanding of Earth's structure.
A rock below the ground is usually only exposed to chemical weathering. A rock on the surface would be exposed to mechanical and chemical weathering and would therefore weather and erode more quickly.

Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
Compare and contrast it with what?
1. Compare 2. Contrast

mechanical digestion - chewing, mixing, churning chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)
compare is when you compare two things that are the same and contrast is when you compare two things that are different.
