• D. All are correct

Answer 1

Answer:

A. 1 and 3

• Correct Answer: Option A) 1 and 3

• Chengal hills are located in the northern part of the state - This is correct. Chengal hills are indeed found in northern Kerala, particularly in districts like Kannur and Kasaragod.

• Laterite hills are a characteristic feature of the Coastal Region - This statement is incorrect. Laterite hills are predominantly found in the midland region of Kerala (between the highlands and the coastal plains), not in the coastal region. The coastal region of Kerala is mainly characterized by sandy beaches, backwaters, and coastal plains.

• Laterite soil is mostly found in areas with high rainfall - This is correct. Laterite soil formation is strongly associated with high rainfall areas through a process called laterization. Kerala's high rainfall contributes significantly to the formation of laterite soil in the state. The heavy rainfall leads to leaching of silica and concentration of iron and aluminum oxides, which are characteristic of laterite soil.
