Explain the differences among sand, silt, and clay, both in their physical characteristics and their behavior in relation to bui
3241004551 [841]

Answer:PHYSICALLY- sand is spherical in shape with large particles up to 0.18g

Silt also contains more of spherical particles with weights around 0.0029g.

Clay contain plate like particles,which are flat or layered. It's particles are generally lower that silt and sand below 0.0029g.

BEHAVIORS Sand particles are coarse and very porous,water can easily penetrate with no particles cohesion,does not retain water, difficult to expand,it is IDEAL FOR BUILDINGS.

Silt particles are also porous with some coarseness and no particles cohesion. retains water and can expand. NOT IDEAL FOR BUILDINGS.

Clay contain particles that are not coarse,they have high cohesiveness,they are not porous as it is difficult for water to penetrate. NOT IDEAL FOR BUILDINGS.

Explanation: Sand particles are coarse,very porous,contains spherical particles with large particles sizes and IDEAL FOR BUILDINGS

Silt particles are also porous, with some coarseness and with little or no particles cohesion, NOT IDEAL FOR BUILDINGS.

Clay soils are not porous water can not easily flow thought it,it is hard when dry and soft when wet. IT IS NOT A GOOD OPTION FOR BUILDINGS.

What is the locating position of the land field?​
BaLLatris [955]

Answer:

Look at a map or globe. Where are places located? Every place has a "global address" that tells exactly where in the world it's located, just as your home has a street address. There are two numbers in a global address--a number for latitude and one for longitude. If you know these numbers and how to use them, you can find any place in the world and give its absolute location. (For definitions, see the glossary at the end of this booklet.)

Why are things located in particular places and how do these places influence our lives? Location can describe how one place relates to another. For example, the Panama Canal was cut across an extremely narrow strip of land in Central America. It provides a shipping lane between the Atlantic and Pacific Oceans, eliminating the need for long, dangerous journeys around South America.
