Kuroshio current is available in ___________.

  1. North Pacific Ocean

  2. North Atlantic Ocean

  3. North Indian Ocean

  4. None of these

A Correct answer
Explanation

The north equatorial current turns northward to the obstruction of Philippines and thus gives birth to the Kuroshio current which flows from Taiwan to Ryuku ridge at 30 degrees N latitude. The Kuroshio current is a warm current. The average temperature and salinity are 8 degrees and 35% respectively.

D Correct answer
Explanation

Factors Influencing Nature and Movement of Ocean Currents:

1. Factors related to the earth’s rotation: Gravitational force and force of deflection.

2. Factors originating within the sea: Atmospheric pressure, winds, precipitation, evaporation and insolation.

3. Factors originating within the sea: Pressure gradient, temperature difference, salinity, density and melting of ice.

4. Factors modifying the ocean currents: Direction and shape of the coast, seasonal variations and bottom topography.

Deforestation results in which of the following?

  1. Drought

  2. Floods

  3. Soil erosion

  4. All of these

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forests naturally absorb water from rainfall and slowly release the water into the rivers. After deforestation, rainfall flows too quickly to the rivers, stripping the topsoil and causing erosion and flooding to occur. When these floods break the river's banks, further problems arise as the path of the river changes and further soil erosion occurs along the river's new path. Deforestation also makes an area more arid, contributing to droughts.

A flash flood is a flood that ________.

  1. Is caused by heavy flooding of a river

  2. Occurs in urban areas

  3. Occurs suddenly and unexpectedly and for a short duration

  4. Is caused by the blocking of drains

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Flash floods are defined by the speed of flooding, not the source or location of flooding. While flash floods are often caused by heavy rainfall, they can also result from other events, such as drain blockages and cloud bursts

  2. Flood

  3. Avalanche

  4. All of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A flood is an overflow of water that submerges land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water. In the sense of "flowing water", the word may also be applied to the inflow of the tide.
