The summer and winter season in a year are caused by __________.

  1. aphelion (farthest) and perihelion (nearest) positions of the Earth from the Sun during the annual revolution

  2. rotation of the Earth on its axis

  3. variation in solar insolation

  4. revolution of the Earth on its inclined axis

D Correct answer
Explanation

The Earth's axis is tilted at an angle of 23.5 degrees. As the Earth revolves around the Sun, this tilt causes different hemispheres to receive varying amounts of direct sunlight throughout the year, resulting in seasons.

'X' is a vent in Earths surface that periodically ejects a column of hot water and steam. The formation of it is a rare phenomenon because it is due to particular hydrogeological conditions which exist at few places on Earth. Taupo volcanic zone in New Zealand is one of its examples. Identify 'X'.

  1. Geyser

  2. Aquifer

  3. Uluru

  4. Spring

A Correct answer
Explanation
  • A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. They are a quite rare phenomenon on Earth due to the precise conditions that are required for them to form. They are mainly clustered near active volcanic areas. 
  • The Taupo Volcanic Zone in New Zealand is 350 km long and 50 km wide and contains volcanoes, hot springs and geysers. The largest geyser ever known, the Waimangu Geyser, sat in the Taupo Volcanic Zone.

An earthquake of magnitude $3$ on Richter scale is ________.

  1. Three times as strong as an earthquake of magnitude $1$

  2. Nine times as strong as an earthquake of magnitude $1$

  3. Ninety times are strong as an earthquake of magnitude $1$

  4. Hundred times as strong as an earthquake of magnitude $1$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Richter scale is logarithmic. Each whole number increase in magnitude represents a tenfold increase in measured amplitude. Therefore, a magnitude 3 earthquake is 10 * 10 = 100 times stronger than a magnitude 1 earthquake.

The weak zones of Earth's crust which are more prone to earthquakes are called _________.

  1. Seismic zones

  2. Fault zones

  3. Danger zones

  4. Both (A) and (B)

D Correct answer
Explanation

Weak zones in the Earth's crust where tectonic plates meet or shift are known as both seismic zones and fault zones. These areas are highly susceptible to earthquake activity.
