According to the ‘Theory of Plate Tectonics,’ when some plates move away from each other, which of the following is formed?
Detailed Solution for Geography Mock Test- 4 - Question 10

According to the theory of plate tectonics, the earth’s lithosphere is broken into distinct plates which are floating on a ductile layer called asthenosphere (upper mantle). Plates move horizontally over the asthenosphere as rigid units.

The lithosphere includes the crust and top mantle with its thickness range varying between 5-100 km in oceanic parts and about 200 km in the continental areas.

The oceanic plates contain mainly the Simatic crust and are relatively thinner, while the continental plates contain Sialic material and are relatively thicker.

Lithospheric plates (sometimes called crustal plates, tectonic plates) vary from minor plates to major plates, continental plates (Arabian plate) to oceanic plates (Pacific plate), sometime a combination of both continental and oceanic plates (Indo-Australian plate).

The movement of these crustal plates causes the formation of various landforms and is the principal cause of all earth movements.

Latitude and altitude of a place determine which of the following climatic elements of a place?
Detailed Solution for Geography Mock Test- 4 - Question 17
Latitude and Altitude: Factors influencing climatic elements
Latitude and altitude are two important geographical factors that significantly influence the climatic elements of a place. They determine various aspects of the climate, including pressure and wind systems, temperature, and rainfall patterns. Here's a detailed explanation:
1. Pressure and Wind System:
- The Earth's rotation and the distribution of solar energy create atmospheric pressure differences, leading to the formation of wind systems.
- Latitude affects the distribution of solar energy, which in turn influences pressure belts and the formation of wind patterns such as trade winds, prevailing westerlies, and polar easterlies.
- Altitude also plays a role in pressure variations, as air pressure decreases with increasing altitude.
2. Temperature:
- Latitude has a significant impact on temperature patterns. As one moves away from the equator towards the poles, temperatures generally decrease.
- The angle at which solar radiation reaches the Earth's surface varies with latitude, affecting the amount of heat received.
- Altitude also influences temperature. Higher altitudes are generally cooler due to the decrease in air density and the associated decrease in heat capacity.
3. Rainfall Pattern:
- Latitude and altitude are key factors in determining the global distribution of precipitation.
- Areas near the equator receive more rainfall due to the convergence of trade winds and the presence of the Inter-Tropical Convergence Zone (ITCZ).
- Altitude affects rainfall patterns through the orographic effect. As air rises over mountains, it cools and condenses, leading to increased rainfall on the windward side and a rain shadow effect on the leeward side.
Conclusion:
In summary, latitude and altitude are crucial factors that determine various climatic elements of a place, including pressure and wind systems, temperature patterns, and rainfall distribution. Understanding these factors is essential in studying and predicting climate patterns and their impacts on ecosystems and human activities.

The temperature decreases from south to north. The average temperature of Chennai on the eastern coast, is between 24° C - 25° Celsius, while in the northern plains, it ranges between 10°C and 15° Celsius. Days are warm and nights are cold. Frost is common in the north and the higher slopes of the Himalayas experience snowfall.

During this season, the northeast trade winds prevail over the country. They blow from land to sea and hence, for most parts of the country, it is a dry season. Some amount of rainfall occurs on the Tamil Nadu coast from these winds as, here they blow from sea to land.

In the northern part of the country, a feeble high pressure region develops, with light winds moving outwards from this area. Influenced by the relief, these winds blow through the Ganga valley from the west and the northwest. The weather is normally marked by clear sky, low temperatures and low humidity and feeble, variable winds.

A characteristic feature of the cold weather season over the northern plains is the inflow of cyclonic disturbances from the west and the northwest. These low-pressure systems originate over the Mediterranean Sea and western Asia and move into India, along with the westerly flow. They cause the much-needed winter rains over the plains and snowfall in the mountains.

The summer months experience rising temperature and falling air pressure in the northern part of the country. Towards the end of May, an elongated low-pressure area develops in the region extending from the Thar Desert in the northwest to Patna and Chota Nagpur Plateau in the east and southeast. Circulation of air begins to set in around this trough.

A striking feature of the hot weather season is the ‘loo’. These are strong, gusty, hot, dry winds blowing during the day over the north and northwestern India. Sometimes they even continue until late in the evening. Direct exposure to these winds may even prove to be fatal. Dust storms are very common during the month of May in northern India. These storms bring temporary relief as they lower the temperature and may bring light rain and cool breeze. This is also the season for localised thunderstorms, associated with violent winds, torrential downpours often accompanied by hail. In West Bengal, these storms are known as the ‘Kal Baisakhi’.

Towards the close of the summer season, pre monsoon showers are common, especially in Kerala and Karnataka. They help in the early ripening of mangoes, and are often referred to as ‘mango showers’.

Read the source given below and answer the questions that follow:

There are six major controls of the climate of any place. They are: latitude, altitude, pressure and wind system, distance from the sea (continentality), ocean currents and relief features.

Due to the curvature of the earth, the amount of solar energy received varies according to latitude. As a result, air temperature generally decreases from the equator towards the poles. As one goes from the surface of the earth to higher altitudes, the atmosphere becomes less dense and temperature decreases. The hills are therefore cooler during summers. The pressure and wind system of any area depend on the latitude and altitude of the place. Thus, it influences the temperature and rainfall pattern. The sea exerts a moderating influence on climate: As the distance from the sea increases, its moderating influence decreases and the people experience extreme weather conditions. This condition is known as continentality (i.e., very hot during summers and very cold during winters). Ocean currents along with onshore winds affect the climate of the coastal areas. For example, any coastal area with warm or cold currents flowing past it, will be warmed or cooled if the winds are onshore.

Finally, relief too plays a major role in determining the climate of a place. High mountains act as barriers for cold or hot winds, they may also cause precipitation if they are high enough and lie in the path of rain bearing winds. The Leeward side of the mountains remains relatively dry.
