Climate refers to the long-term average conditions of the atmosphere, including temperature, precipitation, wind, and humidity, in a specific region.

(i) Latitude: The location of a place in relation to the equator affects its climate. Areas closer to the equator receive more direct sunlight,which results in warmer temperatures and a higher amount of precipitation. Conversely, areas closer to the poles receive less direct sunlight and have colder temperatures and lower precipitation rates.

(ii) Altitude: The higher the altitude of a place, the colder the temperature tends to be. This is because the air pressure decreases with altitude, and as a result, the air expands and cools. Higher altitude areas may also experience more extreme weather conditions, such as frequent thunderstorms or heavy snowfalls.

(iii) Ocean currents: Ocean currents have a significant impact on climate. Warm ocean currents heat up the air above them, leading to warmer temperatures in coastal regions, while cold ocean currents have the opposite effect. The Gulf Stream in the Atlantic Ocean, for example, helps to keep Western Europe warmer than other areas at the same latitude.

(iv) Topography: The shape and features of the land can affect climate. Mountain ranges can create rain shadows, with the side of the mountain facing prevailing winds receiving heavy precipitation, while the other side of the mountain is dry. Coastal areas are also influenced by the presence of mountains, with wind patterns and temperatures changing depending on their location in relation to nearby mountains.

(i) High Temperatures:
The equatorial climate is characterized by high temperatures that remain almost thesame throughout the year, with an average temperature of around 27-28°C.

(ii) High Humidity:
Due to the abundance of rainfall, equatorial regions experience high humidity levels that can be as high as 80-90%.

(iii) Abundance of Rainfall:
Equatorial regions receive a lot of rainfall throughout the year, with an average annual precipitation of around 2000-4000 mm.

(iv) Limited Seasonal Variation:
There is limited variation in seasons in equatorial regions. The regions experience two wet seasons and two dry seasons, with rainfall being spread out throughout the year.

(v) Dense Vegetation:
Due to high temperatures and abundant rainfall, equatorial regions are characterized by dense vegetation such as tropical rainforests.

(vi) Biodiversity:
Equatorial regions are known for their high levels of biodiversity, with a vast array of unique plant and animal species found in such regions.


Weathering is defined as the gradual breaking down or disintegration of rocks by either physical (mechanical) or chemical process. It is a fundamental geologic process that plays a significant role in shaping the Earth’s landscape over long periods of time.


Frost action: This occurs in polar and temperate regions of the world where rocks on high mountains with cracks or joints collect water or snow in them . When the temperature drops during the night or winter, the water in the cracks freezes and melts during the day or summer. Such repeated freezing and melting widen and deepen the cracks which eventually break-down the rock.

Exfoliation: Exfoliation is a geological process that occurs as a result of mechanical weathering, which involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. mechanism behind exfoliation involves the expansion and contraction of rocks in response to temperature changes.
