Practices That Influence Bush Burning -Some poor agricultural practices such as shift cultivation -Hunting for animals -By using fire to clear land for agricultural purposes -Construction of roads and felling of trees. -Grazing purpose by

Erosion is the washing away or wearing of the top soil and sub-soil from land either by water or wind. Process of Soil Erosion -Detachment is when the top soil is actually detached from the rest of the soil. -Movement is when the top soil is transported to another area. -Deposition is where the top

A family trait is a genetic likeness that is passed through the parents” genes to their children or offspring. The traits that are being inherited are present in form of genes.

MEANING OF GRAVITATION Gravitation is a force that has effect on the stability of a body. If an object is tossed up the air, it will fall back to the ground because the earth exerts an attraction on it. This attraction is called gravitational attraction.   The gravitational attraction / force between any two object

MEANING OF SPACE TRAVEL The space outside the sun, earth, star is called outer space. Space travel is the travelling to the outer space beyond this earth. The space travellers are called astronaut. The earth is surrounded by a layer of air called atmosphere which can be divided into about 4 regions: Troposphere Stratosphere Lomosphere

CALCULATION OF WORK DONE AGAINST GRAVITY Suppose you lift an object of mass 1kg from the ground to a height of 1m, the work done in lifting the abject is calculated by using the formula Mgh Mgh = 1 x 1 x 9.8 joules (g = 9.8m 152) joule is the unit of work.
