Rapid rolling or sliding of earth debris without backward rotation of mass is known as
Debris fall is nearly a free fall from vertical or overhanging face.
The capacity of rocks to allow water to pass through it is called_________
Porosity is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock. Permeability is a measure of the ease with which water can move through a porous rock.
The expansion of the salt depends on
Salt expansion normally takes place in arid climates as strong heating causes strong evaporation; leading to its expansion. It is known as salt weathering.
Which is the force that continuously elevate or build up parts of the earth’s surface?
Endogenic forces are continuously building up the earth’s surface. The internal forces within the earth are known as endogenic forces.
Weathering can be defined as ___________

Which one of the following helps in aerating the soil.
Meso fauna comprises worm-like animals. They help in aeration and mixing mineral and organic matter.
The given picture shows the process of folding under
Folding is a process in which rocks have been molded due to compression beneath the earth surface. This is an endogenic force.
In weathering ________
Weathering is an in-situ or on-site process. Very little or no motion of materials takes place in weathering.
Soil developing from recently deposited alluvium or glacial is considered as young and they exhibit no
A soil becomes mature when all soil-forming processes act for a sufficiently long time developing a horizon. The alluvium or glacial are considered as young soils.
Which one of the following is affected by hydration process?
Salts in pore spaces undergo rapid and repeated hydration and help in rock fracturing.
