Consider the following statements regarding Sargasso Sea.
1. The Sargasso Sea is located entirely within the Pacific Ocean.
2. It is bounded by four ocean currents forming an ocean gyre.
3. It is the only sea without a land boundary.
The Sargasso Sea, located entirely within the Atlantic Ocean, is the only sea without a land boundary. It is
bounded by four ocean currents forming an ocean gyre.
It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and
often calm blue water.
The sea is bounded on the west by the Gulf Stream, on the north by the North Atlantic Current, on the east by
the Canary Current, and on the south by the North Atlantic Equatorial Current, the four together forming a
clockwise-circulating system of ocean currents termed the North Atlantic Gyre.

Shallow focus earthquake are more violent and affect a large area than deep earthquakes
False. They are violent but affect smaller area
Humus content is low in humid tropical and equatorial regions while relatively higher in colder climates
True
humid tropical and equatorial climates, bacterial growth and action is intense and dead vegetation is rapidly oxidised leavingvery low humus content in the soil
What is podzolisation
process of soil formation especially in humid regions involving principally leaching of the upper layers with accumulation of material in lower layers and development of characteristic horizons.
Asthenosphere is the source of mantle plume
False
Core- mantle boundary is the source of mantle plume
