Which of the following is a type of wave ____________.

1. Ripples

2. Seas

3. Swells

4. All are the types of waves

Correct Option: D
Explanation:

Ripples are the instant effect of wind on water and they die down as quickly as they form, as the surface tension of the water dampens their efforts.

Waves always travel in the same direction as the wind is blowing: if the wind changes then the waves change with it. Wave size is determined by the strength of the wind, the length of time it has been blowing and the distance it has blown over or the ‘fetch’.

When strong winds blow for longer than a few hours, it gives the water sufficient energy that it then takes on a character of its own. This character and movement is known as swell, and it will march across open areas of water independent of the wind.

Which is the busiest of Ocean trade routes ?

1. North Pacific Ocean

2. Indian Ocean

3. Arctic Ocean

4. North - Atlantic Ocean

Correct Option: D
Explanation:
Atlantic Ocean
The busiest ocean from the point of view of trade is Atlantic Ocean.

Large movements of ocean water from places of warm temperature to low temperature or vice versa are ______________.

1. Drifts

2. Ocean currents

3. Waves

4. Tides

Correct Option: B

Kuroshio current is available in ___________.

1. North Pacific Ocean

2. North Atlantic Ocean

3. North Indian Ocean

4. None of these

Correct Option: A
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.

Which factors influence ocean currents?

1. Earth's rotation

2. Winds across ocean

3. Density of water

4. All of the above

Correct Option: D
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.

Christmas is celebrated in summer in

1. Japan

2. India

3. Australia

4. None of these

Correct Option: C
Explanation:

Christmas is celebrated in summer in Australia because Christmas is celebrated everywhere on 25 December, and that date — in most of Australia — is in the summertime. And, for Christians at least, Christmas is fundamentally about the birth of Christ — whenever that may have occurred — and not about winter.

State whether these sentences are true (T) of false (F).
The axis of the earth makes an angle of 23 V & with its orbital plane.
1. True

2. False

Correct Option: B
Explanation:

False

Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.

The earth while orbiting makes various angles with the sun's rays. On 22nd December, the rays are vertical on earth at _______.

1. $23 {\frac {1}{2}}^o$

2. $30^o$ North

3. $23 {\frac {1}{2}}^o$ South

4. $30^o$ South

Correct Option: C
Explanation:
• Sun rays falling vertically move between 23 and 1/2 degrees north and 23 and 1/2 degrees south latitudes throughout the year. On 22nd december, the sun rays fall vertically at the 23 1/2 degrees south.

The inclination of the earth's axis to plane of the orbit is ______________.

1. $90^o$

2. $23{\frac {1}{2}}^o$

3. $0^o$

4. $66{\frac {1}{2}}^o$

Correct Option: B
Explanation:

The axis of the Earth is tilted at an angle of 23 1/2° from a perpendicular to the orbital plane.  This tilting of the axis is called the inclination of the Earth's axis. Due to this inclination, the axis of the Earth makes an angle of 66 1/2° with the plane of the Earth's orbit.

Which of the followings is the shortest day in the southern hemisphere?

1. March 21

2. June 21

3. September 22

4. December 23

Correct Option: B
Explanation:

On 21 June sun rays fall vertically over the Tropic of Cancer. This position of the Earth is called Summer Solstice. On this day, It is considered the longest daylight time in Northern Hemisphere but in Southern Hemisphere, it is considered as the shortest daylight time.
