The major movements of the ocean waters can be classified into three. They are: Waves Tides Ocean Currents Waves and the ocean currents are horizontal movements of ocean waters while the tide is a kind of vertical movement of the ocean water. Waves Waves are nothing but the oscillatory movements that result in the rise … Read more

DMPQ-Discuss how Climate change is effecting world’s Coral reefs.

Coral reefs harbour the highest biodiversity of any ecosystem globally and directly support over 500 million people worldwide, mostly in poor countries. They are among the most threatened ecosystems on Earth, largely due to unprecedented global warming and climate changes, combined with growing local pressures. A spike of 1–2°C in ocean temperatures sustained over several … Read more

DMPQ-. Discuss the Erosional Landforms formed by Wind.

Pediplains When the high relief structures in deserts are reduced to low featureless plains by the activities of wind, they are called as Pediplains. Deflation Hollows Deflation is the removal of loose particles from the ground by the action of wind. When deflation causes a shallow depression by persistent movements of wind, they are called … Read more

Decline of … Read more

DMPQ-Discuss different types of physical or mechanical weathering.

. Physical or mechanical weathering processes depend on some applied forces. Unloading and Expansion Removal of overlying rock load because of continued erosion causes vertical pressure release. Thus, the upper layers of the remaining rock expand to produce disintegration of rock masses. Fractures will develop roughly parallel to the ground surface. In areas of curved … Read more
