geomorphology & earth landforms section 3 MCQ Questions & Answers Detailed Explanation

Answer: (a)

Hydrolysis is the weathering reaction that occurs when the two surfaces of water and compound meet. It involves the reaction between mineral ions and the ions of water (OH- and H+), and results in the decomposition of the rock surface by forming new compounds. Temperatures usually stay high (above 70) throughout the year.

Humid Subtropical climate is known for hot humid summers. During the summer the average temperature is between 70 and 80 degrees.

Answer: (a)

The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer (extends from where the crust ends to about 2,890 km), while the crust is the thinnest layer.

The crust ranges from 5–70 km in-depth and is the outermost layer.
