Question 1

Daily weather map showing isobars is an example of:

Accepted Answer

A daily weather map displaying isobars is an illustration of an isopleth map. Isopleth maps represent a theoretical surface using lines that connect locations with the same values.

Question 2

Consider the following description: 1. Annual and daily range of temperatures is low. 2. Precipitation occurs throughout the year. 3. Precipitation varies between 50 cm - 250 cm. What is this type of climate?

Accepted Answer

The description provided indicates a climate with low annual and daily temperature ranges, consistent precipitation throughout the year, and precipitation levels ranging from 50 cm to 250 cm. These characteristics are typical of a Marine West coast climate, which is characterized by mild temperatures, high humidity, and moderate to high precipitation levels throughout the year.

Question 3

Assertion (A): Areas near the equator receive rainfall throughout the year. Reason (R): High temperatures and high humidity cause convectional rain in most afternoons near the equator. In the context of the above two statements, which one of the following is correct?

Accepted Answer

In areas near the equator, rainfall occurs throughout the year due to high temperatures and humidity causing convectional rain in most afternoons. The assertion that areas near the equator receive rainfall throughout the year is true, and the reason for this is that high temperatures cause the atmospheric air to heat up and rise. As the air cools down, it precipitates while the cooler air descends back down. This phenomenon explains why rainfall is a common occurrence near the equator.

Question 4

The graph given below shows the mean average monthly temperatures (in ºC) and mean monthly rainfall (in cms) of a place. This graph is indicative of which one of the climatic zones of the world?

Accepted Answer

The provided graph displays the average monthly temperatures and rainfall for a specific location. The temperature on the graph falls between 15°C and 25°C. Based on this temperature range and the rainfall not exceeding 25 cm, the graph represents the wet and dry tropical climatic zone.

Question 5

For short-term climatic predictions, which one of the following events, detected in the last decade, is associated with occasional weak monsoon rains in the Indian sub-continent?

Accepted Answer

El Nino and La Nina are two different phases within the El Nino-Southern Oscillation (ENSO) cycle, which influences occasional weak monsoon rains in the Indian sub-continent.
