- Question 1 of 10
1. Question
1 pointsCategory: Geography & EnvironmentWhich of the following statements is/are correct about the “Solar System”?
- All planets rotate around their axis in counter-clockwise motion.
- Mars is often considered as Earth’s twin because of their close proximity in size, mass and density
Select the correct answer using the codes given below:
Correct
The Solar System.
Statement 1 is incorrect: Prograde rotation indicates that the motion is in the same direction as the Sun’s rotation. Retrograde rotation is in the opposite direction. Most planets in our solar system, including Earth, rotate counter-clockwise or prograde direction, but Venus and Uranus are said to have a retrograde or clockwise rotation around their axis. The tilt angle of a planet is measured relative to the orbital plane of the planet, and most planets’ axes form an almost perpendicular angle to the orbital plane.
Statement 2 is incorrect: Venus, twice the distance away from the sun, is the next closest planet after Mercury. It is often considered as Earth’s twin because of their close proximity in size, mass and density.

2. Question
1 pointsThe term “Oort Cloud” is related to which of the following?
Correct
The Oort cloud is the most distant region of our solar system. Even the nearest objects in the Oort cloud are thought to be many times farther from the Sun than the outer reaches of the Kuiper Belt. Unlike the orbits of the planets and the Kuiper Belt, which lie mostly in the same flat disk around the Sun, the Oort cloud is believed to be a giant spherical shell surrounding the rest of the solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort cloud might contain billions, or even trillions, of objects.

3. Question
1 pointsWhich of the following statements is/are correct about “Great and Small Circles”?
- A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth.
- Equator and all longitudes are great circles.
- Circles which do not pass through the centre of the earth are the small circles.
Select the correct answer using the codes given below:
Correct
A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles. The shortest distance between any two points on the Earth lies along a great circle. Circles which do not pass through the centre of the earth are the small circles.

4. Question
1 pointsWhich of the following statements is/are correct about “Lithosphere or Crust”?
- Crust is only 10% of the Earth’s mass and contains all known life in the universe.
- Continental lithosphere is slightly denser than Oceanic lithosphere.
Select the correct answer using the codes given below:
Correct
Lithosphere or Crust.
Statement 1 is incorrect: The crust is called Lithosphere because it is a sphere of solid rocks (LITHOS meaning stones or rocks). Crust is only 1% of earths mass and contains all known life in the universe.
Statement 2 is incorrect: There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere.

5. Question
1 pointsWhich of the following statements is/are NOT correct about “Block Mountains”?
- The orogenic forces lead to the formation of Block Mountains.
- Examples of Block Mountains are the Atlas, Zagros and Elburg mountains.
Select the correct answer using the codes given below:
Correct
Block Mountains.
Statement 1 is incorrect: The forces of faulting, also known as epeirogenic forces, lead to the formation of Block Mountains.
Statement 2 is incorrect: Examples of Block Mountains are the Vosges (France) and the Black Forest Mountains in Europe. Salt Range of Pakistan and Sierra Nevada mountains of California, USA.

6. Question
1 pointsWhich of the following are the causes of “Ocean Currents”?
- Level of salinity
- Temperature
- The Earth’s rotation
- Earthquakes or storms
Select the correct answer using the codes given below:
Correct
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents. Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events such as huge storms and underwater earthquakes can also trigger serious ocean currents, moving masses of water inland when they reach shallow water and coastlines. Earthquakes may also trigger rapid downslope movement of water-saturated sediments, creating strong turbidity currents.

- Question 7 of 10
7. Question
1 pointsWhich of the following is/are NOT “Warm Ocean Current”?
- The Gulf Stream
- The North Atlantic Drift
- The Labrador Current
- The Oyashio Current
Select the correct answer using the codes given below:
Correct
Cold currents flow toward the equator on the eastern side of ocean basins. Examples of cold ocean currents include the Canary Current in the North Atlantic, the California Current in the North Pacific, and the Benguela Current in the South Atlantic. Cold currents can also flow out of far northern regions. The Labrador Current flows out of Baffin Bay and past Labrador, the coastal part of the Canadian province of Newfoundland. The current carries icebergs from Baffin Bay, creating a hazard for ships in the North Atlantic. The Labrador Current meets the Gulf Stream off the coast of Newfoundland. When warm, moist air from the Gulf Stream blows over the cold Labrador Current, water vapor condenses. This results in some of the thickest fogs in the world. Two other important cold currents originate in northern regions. The East Greenland Current flows into the North Atlantic through the Strait of Denmark. The Oyashio Current flows through the Bering Strait between Siberia and Alaska and into the North Pacific.
