Adaptations are special features that allow a plant or animal to live in a particular place or habitat. The ability of living organisms to adjust themselves to the surroundings is called as adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.  

Desertification is the process by which a previously biologically productive land becomes progressively dried till it eventually becomes a desert. Or Desertification is the extension or encroachment of desert into habitable land. The geographical zones near and around  the desert are highly prone to this environmental hazard.Man”s activities have contributed environmental degradation such as exposing

Deforestation is defined as the clearing of forest wood for farming or purposes without immediate replanting. This act of cutting down trees indiscriminately by the activities of man is encouraged by the following factors; -Bush burning -Building of schools, houses etc. -felling of trees for firewood -Construction of roads and bridges.   Reasons for Deforestation

Flood is defined as an overflow of water that submerges land which is usually dry. Flooding occurs when a part of the soil or land is submerged under water. Some part of the land are prone to flooding, this is due to the soil structure Types of Flooding Flash floods- This occurs within a very

Bush burning is the act of setting forest, weed and grasses on fire deliberately either with a purpose or not. 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. Genes are the hereditary unit. The characters or traits that can be passed from the parents to the offspring include the following; I- Skin

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.  

A force can be defined as any action that makes or tries to move, stop or alter the speed of a body in a given direction. TYPES OF FORCE There are two types of force namely: Contact force Non-contact   CONTACT FORCE These are  forces which sources are in contact with the body to which

EFFECTS OF POLLUTION Environment Degradation Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide
