The removal of rock, layer by layer due to weathering is called Exfoliation. Rocks are generally poor conductors of heat. The effect of daily heating and cooling is confined to surface layers of rocks. The outer layer of rock is heated up and expands during the day while the inner layer of rock remains cool. The outer layers eventually peel off (like an onion skin), exposing the inner layers to the surface for further exfoliation.

Cape Town region of South Africa has Mediterranean type of climate. Cape Town has a Mediterranean-style climate: wet and cool winters, dry and warm summers.

The Tundra Region gets no rainfall throughout the year. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes.

High mean temperature, high relative humidity and heavy rainfall (well distributed all over the year) are the characteristic features of the Equatorial region. A tropical rainforest climate is a tropical climate usually found within 10° to 15° latitude of the equator, and has at least 60 mm (2.4 inches) of rainfall every month of the year.

Contours' are lines connecting places having Equal height. Contour lines are isolines joining places that have the same height value. Another common isoline is the isobar, a line that joins places with the same atmospheric pressure.

The equatorial regions receive rainfall throughout the year. The annual rainfall is generally about 250 cms.

The Tropical Rain forest type of climate is characterised by Heavy rain and high temperatures throughout the year. Because tropical rain forests lie near the equator, the days do not get shorter in winter and longer in summer. A day has about 12 hours of sunlight throughout the year. The average rainfall in the rain forest is the highest for any ecoregion on Earth. The climate in tropical rain forests is constantly warm and moist.

After summer season the frequency of tropical cyclones in the Bay of Bengal maximum because at that time their is high pressure area.
