Answer 1

Soil is a natural resource that can be categorised into different soil types, each with distinct characteristics that provide growing benefits and limitations.

Identifying the type of soil you require for a project is paramount to support the healthy growth of plant life.

Soil can be categorised into sand, clay, silt, peat, chalk and loam types of soil based on the dominating size of the particles within a soil.

There are three types of coal-

1.lignite- It is Brown to black in colour and woody form of coal .it can be easily mined .it has a high moisture content and less carbon content so it causes more pollution than other varieties of coal.

2.bituminous- it is also called the industrial coal or brown coal .it is dull black or blackish brown in colour with relatively higher percentage of carbon content .it is the mostly used coal.

3.anthracite- it is hard and Shiny with highest percentage of carbon content. it burns without much fumes ,so it is mainly used for smelting of metals.
