Question 10

(a) Explain convection currents. Give two example​

Answer 1

Explanation:

The pressure which acts in the horizontal direction of the soil is known as lateral pressure. It is an important factor that is considered in the design of the bridge abutment, retaining walls, basement, tunnels etc. ... There are three types of the lateral earth pressure as follows, 1) Active, 2) Passive, and 3) at rest.

Answer 2

Answer:

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.
