Question

1. which type of weathering is most common where the average yearly temperature is 5°c and the average yearly precipitation is 45 cm?
2. which type of weathering is most common where the average yearly temperature is 20°c and the average yearly precipitation is 100 cm?
3. the amount of chemical weathering will increase if air temperature ____________ and precipitation ____________.

Explanation:

Step1: Locate the first point on the graph

Find the intersection of 5°C on the x - axis (average yearly temperature) and 45 cm on the y - axis (average yearly precipitation). It falls in the area of moderate chemical weathering with frost action.

Step2: Locate the second point on the graph

Find the intersection of 20°C on the x - axis and 100 cm on the y - axis. It falls in the area of strong chemical weathering.

Step3: Analyze chemical weathering factors

Chemical weathering is enhanced by higher temperatures and more precipitation. So, the amount of chemical weathering will increase if air temperature increases and precipitation increases.

Answer:

1. Moderate chemical weathering with frost action
2. Strong chemical weathering
3. increases; increases
