What is the average salinity of the ocean?
View Answer
Answer: Option B
Explanation:
Explanation:
1. Salinity is the total amount of dissolved salts in seawater.
2. It is typically measured in parts per thousand (ppt or โฐ).
3. The average salinity of the world's oceans is approximately 35 parts per thousand.
4. This means that in every 1,000 grams of seawater, there are 35 grams of salt (mostly sodium chloride).

'El Nino' is characterized by:
View Answer
Answer: Option B
Explanation:
Explanation:
1. El Nio is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
2. During an El Nio event, trade winds weaken, allowing warm water from the western Pacific to flow eastward.
3. This warming significantly alters global weather patterns.
4. In India, it is often associated with weaker monsoons and drought conditions.

The 'Jet Streams' are found in the:
View Answer
Answer: Option B
Explanation:
Explanation:
1. Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere.
2. They typically flow from west to east.
3. They are located near the altitude of the tropopause, which is the boundary between the Troposphere and the Stratosphere.
4. These winds play a crucial role in determining weather patterns and influencing the path of storms.

Mist is caused by:
View Answer
Answer: Option B
Explanation:
Explanation:
1. Mist is a phenomenon caused by small droplets of water suspended in air.
2. It occurs when water vapor in the air cools and undergoes condensation into tiny liquid droplets.
3. It is similar to fog but less dense, allowing for greater visibility (usually more than 1 km).
4. It often forms near the ground in humid conditions when the air temperature drops.

'Sargasso Sea' is unique because it:
View Answer
Answer: Option B
Explanation:
Explanation:
1. The Sargasso Sea is a region in the North Atlantic Ocean.
2. It is unique because it is the only 'sea' on Earth that has no land boundaries.
3. It is defined by four ocean currents: the Gulf Stream, the North Atlantic Current, the Canary Current, and the North Atlantic Equatorial Current.
4. It is named after the 'Sargassum' seaweed that floats on its surface.

'Chinook' is a local wind of:
View Answer
Answer: Option A
Explanation:
Explanation:
1. Chinook winds are a type of 'foehn' wind.
2. They are warm, dry winds that blow down the eastern slopes of the Rocky Mountains in North America (USA and Canada).
3. They can cause rapid temperature increases, sometimes melting thick snow in a matter of hours.
4. For this reason, they are often nicknamed 'Snow Eaters'.

The study of the shape and features of the Earth's surface is:
View Answer
Answer: Option B
Explanation:
Explanation:
1. Geomorphology is a subfield of geography and geology.
2. It focuses on the study of landforms (mountains, valleys, plains) and the processes that create and change them (erosion, plate tectonics, weathering).
3. It seeks to understand why the Earth's surface looks the way it does.
4. Topography is the detailed mapping or description of these features, while Geomorphology is the study of the underlying science.

Which is the highest clouds in the atmosphere?
View Answer
Answer: Option C
Explanation:
Explanation:
1. Clouds are classified by their altitude and appearance.
2. Cirrus clouds are high-altitude clouds, typically forming above 6,000 meters (20,000 feet).
3. They are thin, wispy, and composed of ice crystals due to the freezing temperatures at that height.
4. Stratus and Cumulus are low-level clouds, while Nimbus refers to rain-bearing clouds.

'Spring Tides' occur when:
View Answer
Answer: Option B
Explanation:
Explanation:
1. Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans.
2. When the Sun, Moon, and Earth are aligned in a straight line (during New Moon and Full Moon), their gravitational forces combine.
3. This results in the highest high tides and lowest low tides.
4. These are called 'Spring Tides' (not related to the season), while 'Neap Tides' occur when the Sun and Moon are at right angles.
