1)biological weathering diagram with neat labelled
2)block disintegration diagram with neat labelled

Answer 1

1)  Biological weathering is the process by which plants pulverize rocks using their roots or root exudates.

• The postponed process could significantly affect how a landscape develops.

• A landscape's formation could be significantly impacted by the postponed process.  
• When biotic activity reaches its maximum, biological weathering declines as soil thickness increases because biotic activity no longer has as much of an impact on weathering.
• There are three different types of biological weathering: lichens, organic matter, and burrowing animals.

2)When rocks split along joints, they disintegrate into huge rectangular blocks. Granular disintegration: Due to temperature changes, the rock's granules might become dislodged and fall out, leaving a pitted, uneven surface. Different kinds of minerals make up rocks.

• Block disintegration refers to the fracturing of rocks into individual blocks along joints
• It frequently happens in areas where there is a significant difference between the daily range of temperatures. Desert, for instance.
• This sort of weathering is mechanical. The fissures in the rocks weaken and eventually break apart as blocks as they expand and compress as a result of differential heating (hot during the day and cool at night).
