The question asks us to evaluate two statements related to the Indian monsoon and rainfall patterns. We need to determine if each statement is correct based on geographical and climatological principles of India.
C) Both 1 and 2
Both statements are factually correct regarding the Indian monsoon and rainfall distribution. The duration of the monsoon is longer in the south and shorter in the north, and rainfall in the northern plains generally diminishes as one moves from east to west.
The question asks about the characteristic climate of the Tropical Savannah Region. To answer this, we need to recall the typical climatic features of savannahs, particularly regarding rainfall patterns.
Correct Option: D) A definite dry and wet season
The question asks about the primary reason for seasonal variations in the length of daytime and night-time. This phenomenon is a direct consequence of how the Earth interacts with the Sun as it orbits, specifically considering the Earth's axial tilt.
Correct Option: D) revolution of the earth on a tilted axis
This option correctly identifies the two crucial factors: the Earth's revolution around the Sun and its axial tilt. Both are necessary to explain the seasonal variations in day and night length.
The question asks about the cause of thunder during a thunderstorm. We need to evaluate each given statement to determine if it accurately describes the phenomenon of thunder.
Correct Option: D) None of the above produces the thunder
The question asks for the reason(s) behind the higher annual temperature range in continental interiors compared to coastal areas. This phenomenon is primarily explained by the differing thermal properties of land and water.
A) 1 only — The thermal difference between land and water is the fundamental reason for the varying annual temperature ranges between continental interiors and coastal areas. Land heats and cools faster than water, leading to more extreme temperatures inland and moderated temperatures near the coast.
The question asks why tropical cyclones do not originate in specific regions: the South Atlantic and South-Eastern Pacific in tropical latitudes. Tropical cyclones require a specific set of atmospheric and oceanic conditions to form. We need to identify which of the given options represents a critical missing condition in these regions.
B) Inter-Tropical Convergence Zone seldom occurs. The ITCZ is a crucial ingredient for tropical cyclone formation, providing the necessary atmospheric instability and convergence. Its general absence or weakness in the South Atlantic and South-Eastern Pacific tropical regions is the primary reason why cyclones rarely form there.
