What are the cohesive and cohesionless soils and how thr are differe from each other?
Cohesive soils contain fine particles that stick together due to electrostatic forces, while cohesionless soils have non-cohesive particles that do not stick together. Cohesive soils exhibit plasticity and can be molded when wet, while cohesionless soils have higher permeability and do not retain shape when dry. Additionally, cohesive soils tend to have higher shear strength compared to cohesionless soils.
Does granular soil have cohesion?
Granular soils typically have low cohesion due to the absence of clay particles that provide cohesion in fine-grained soils. Granular soils rely more on friction between particles for strength and stability.
Why does water clump soil together?
Water acts as a binding agent in soil by forming bridges between soil particles, helping them stick together. This process is known as cohesion, and it enhances the soil's structure and stability. Additionally, water allows soil particles to slide past each other more easily, leading to better soil aggregation.
What soil would erode the fastest?
Sandy soil tends to erode the fastest due to its loose structure and lack of cohesion. The particles in sandy soil are easily detached and carried away by water or wind erosion processes.
Is type c soil the least stable soil?
No, type C soil is not the least stable soil. Type C soil is moderately cohesive and may require some engineering considerations for excavation. Type D soil is considered the least stable soil due to its lack of cohesion and tendency to flow when excavated.

What two forces help soil hold water?
Adhesion and Cohesion

What is apparent cohesion?
geology) In soil mechanics, the resistance of particles to being pulled apart due to the surface tension of the moisture film surrounding each particle. Also known as film cohesion.
What does sandy soil have better than clay soil?
it has better texture
Why cohesion is zero in normally consolidated clays?
In normally consolidated clays, the soil particles are densely packed and in contact with each other, which prevents the development of cohesion. Cohesion in soils arises from the attractive forces between soil particles, but in normally consolidated clays, these forces are not significant due to compaction. This results in zero cohesion in normally consolidated clays.
How do the strength and cohesion of clay-rich regolith or soil change with the addition of water?
The strength of clay-rich regolith or soil increases with the addition of water due to an increase in cohesion between particles. This cohesion arises from the formation of water bridges between clay particles, which helps bind them together and improve the overall strength of the material. However, if too much water is added, it can lead to increased plasticity and reduced strength due to excessive lubrication between particles.

Do plants grow better in soil or clay?
soil as there are more nutrients
Can plants grow better in water or soil?
well it better in soil because soil has more nutrients
