1. Which of the following is an example of direct source to study interior of the earth?
[A] Gravitation
[B] Sesimic activity
[C] Magnetic field
[D] Volcanic Eruption
Show Answer
Correct Answer: D [Volcanic Eruption]
Notes:
Temperature increases when we go deep into the earth. Therefore scientist depends on some sources to study interior of the earth. Based on the nature of source they are divided into two types:
Direct sources- Surface rocks, volcanic eruption forms etc.
Indirect sources- Magnetic field, gravitation, seismic activity, meteors etc.

[B] Isohytes
[C] Isocons
[D] Isotherms
Show Answer
Correct Answer: B [ Isohytes ]
Notes:
An isohyet or an isohyetal line is a line that joins places of same rainfall on a map within a given time period. A map of isohyets is also known as an isohyetal map.
3. “Nebular Hypothesis” is a theory which is related to origin of the following?
[A] Sun

5. Which of the following islands is divided into Brunei, Indonesia and Malaysia?
[A] Sebatik Island
[B] Island of Borneo
[C] Madura Island
[D] Island of Siberut
Show Answer
Correct Answer: B [Island of Borneo]

6. Comparing to other regions, the day night temperature difference will be maximum in which among the following regions?
[A] Tundra
[B] Mediterranean
[C] Tropical Deserts
[D] Equatorial
Show Answer
Correct Answer: C [Tropical Deserts]
Notes:
Tropical desert regions, such as the Sahara Desert, experience significant day-night temperature differences. During the day, temperatures in these areas can become extremely hot, often exceeding 100 degrees Fahrenheit (38 degrees Celsius), while nighttime temperatures can drop significantly, sometimes plummeting to near-freezing levels, particularly in desert areas with low humidity. This makes the day-night temperature difference in tropical deserts quite substantial.
7. What is the correct sequence of stages in the life cycle of a star?
[A] Nebula → Red Dwarf → White Dwarf → Supernova
[B] White Dwarf → Red Dwarf → Nebula → Supernova
[C] Supernova → Nebula → White Dwarf → Red Dwarf
[D] Nebula → White Dwarf → Red Dwarf → Supernova
Show Answer
Correct Answer: A [Nebula → Red Dwarf → White Dwarf → Supernova]
Notes:
Stars have a life cycle that starts from a nebula, a cloud of dust and plentiful gas. From this, a protostar is formed which, if it has sufficient mass, becomes a red dwarf. As the star exhausts its hydrogen, it becomes a white dwarf and eventually, it may explode as a supernova. Not all stars go through the same cycle, as it depends on their mass.

Most of them live in the main asteroid belt—a region between the orbits of Mars and Jupiter. Some asteroids are hundreds of miles in diameter, but many more are as small as pebbles. Most asteroids are made of different kinds of rocks, but some have clays or metals, such as nickel and iron.
10. Which of the following is the reason behind the different seasons to occur?
[A] Sun is moving around the earth
[B] Of revolution of the earth around the sun on its orbit
[C] Tilt of Earth’s axis
[D] All of the above
Show Answer
Correct Answer: C [Tilt of Earth’s axis]
Notes:
The four seasons happen because of the tilt of the Earth’s axis. At different times of the year, the sun’s rays hit different parts of the globe more directly. The angle of the Earth’s axis tilts the Northern Hemisphere towards the sun during the summer.
