Q) effect of waterlogging​

Answer 1

Answer:

cutting down of trees in a large area is called deforestation

Explanation:

if there is no rain for longer time and there are cracks in the soil is soil erosion

Answer 2

Explanation:

Detachment and movement of topsoil or soil material from the upper part of the profile by the action of wind or running water especially as a result of changes brought about by human activity (such as unsuitable or mismanaged agricultural methods).

Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund

Waterlogging is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail.

Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). This is usually measured in. (note that this is technically dimensionless).

noun. mass noun. The removal of silt from a body of water.

Waterlogging lowers oxygen levels in the root zone, which reduces plant growth. Waterlogging increases the reduction potential of the soil and changes the chemical equilibrium of many elements which then enter the soil-water solution in their ionic forms
