Question 1 of 10
1. Question
2 points
Consider the following statements regarding Sea floor.
1. Volcanic eruptions are common along the mid-oceanic ridges.
2. The age of the rocks decreases as one moves away from the crest.
3. The ocean crust rocks are much younger than the continental rocks.
Which of the above statements is/are correct?
Correct
Solution: b)
Sea floor spreading is verified using these phenomena:
• It was realised that all along the mid-oceanic ridges, volcanic eruptions are common and they bring huge amounts of lava to the surface in this area. The sediments on the ocean floor are unexpectedly very thin.
• The age of the rocks increases as one moves away from the crest.
• The ocean crust rocks are much younger than the continental rocks.
• The sediments on the ocean floor are unexpectedly very thin.
• The deep trenches have deep-seated earthquake occurrences while in the mid-oceanic ridge areas, the quake foci have shallow depths.

Consider the following statements regarding Thermosphere.
1. In thermosphere temperature decreases very rapidly with increasing height.
2. Radio waves transmitted from the earth are reflected back to the earth by this layer.
3. The space shuttle and the International Space Station both orbit Earth within the thermosphere.
Which of the above statements is/are correct?
Correct
Solution: c)
The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km to between 500 and 1,000 km above our planet.
This layer helps in radio transmission. In fact, radio waves transmitted from the earth are reflected back to the earth by this layer.

The speed of tsunami waves in Ocean largely depends on
Correct
Solution: a)
Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.

Question 6 of 10
6. Question
2 points
1. Consider the following statements.
1. Earth’s crust is the thinnest of all the major layers of earth.
2. The crust is thicker on the continent than on the ocean floor.
3. The oceanic crust mainly consists of manganese and iron.
Which of the above statements is/are correct?
Correct
Solution: a)
The uppermost layer over the earth’s surface is called the crust. It is the thinnest of all the layers. It is about 35 km. on the continental masses and only 5 km on the ocean floors.
The main mineral constituents of the continental mass are silica and alumina. It is thus called sial (si-silica and al-alumina). The oceanic crust mainly consists of silica and magnesium; it is therefore called sima (si-silica and ma-magnesium).

Hot Spots within the earth help produce Geothermal Energy. What are these ‘Hot Spots’?
Correct
Solution: b)
Due to geological changes, molten rocks formed in the deeper hot regions of earth’s crust are pushed upward and trapped in certain regions called ‘hot spots’.
When underground water comes in contact with the hot spot, steam is generated. Sometimes hot water from that region finds outlets at the surface. Such outlets are known as hot springs.

Consider the following statements regarding Monsson rainfall.
1. Half of India’s rainfall is received from Northeast monsoon.
2. Northeast monsoon in India is almost confined to the Southern peninsula.
3. Maldives, Sri Lanka and Myanmar also record rainfall during Northeast monsoon.
Which of the above statements is/are correct?
Correct
Solution: c)
India receives rainfall during two seasons. About 75 per cent of the country’s annual rainfall is received from the Southwest monsoon between June and September. The Northeast monsoon, on the other hand, occurs during October to December, and is a comparatively small-scale monsoon, which is confined to the Southern peninsula.
Also called the winter monsoon, the rainfall associated with the Northeast monsoon is important for Tamil Nadu, Puducherry, Karaikal, Yanam, coastal Andhra Pradesh, Kerala, north interior Karnataka, Mahe and Lakshadweep.
Some South Asian countries such as Maldives, Sri Lanka and Myanmar, too, record rainfall during October to December.
Tamil Nadu records about 48 per cent (447.4 mm) of its annual rainfall (943.7 mm) during these months, making it the key factor for undertaking agricultural activities and reservoir management in the state.

Consider the following statements.
1.Almost all the world deserts are confined within the 30 to 45 degrees parallels of latitude north and south of the equator.
2.Deserts lie in the trade wind belt on the western parts of the continents where Trade winds are off-shore.
Which of the above statements is/are correct?
Correct
Solution: b)
The pattern that can be identified in the location of the world’s deserts is that almost all the deserts are confined within 15 to 30 degrees parallels of latitude north and south of the equator.
They lie in the trade wind belt on the western parts of the continents where Trade winds are off-shore. They are bathed by cold currents which produced a ‘desiccating effect’ so that moisture is not easily condensed into precipitation.
Dryness or aridity is the key note. Such deserts are tropical hot deserts or ‘Trade wind deserts’. They include the Great Sahara Desert; Arabian, Iranian and Thar Deserts; Kalahari, Namib, and Atacama Deserts; the Great Australian Deserts and the deserts of the south-west U.S.A, and northern Mexico.
In the continental interiors of the mid-latitudes, the deserts such as the Gobi and Turkestan are characterised by extremes of temperatures.

Warm moist summer, cool dry winter, great annual temperature range, rainfall throughout the year are the characteristic feature of which type of climate?
o a) Hot, Wet Equatorial climate
o b) Sudan climate
o c) British type climate
o d) China type climate
Correct
Solution: d)
This type of climate is found on the eastern margins of continents in warm temperate latitudes, just outside the tropics. It has comparatively more rainfall than the Mediterranean climate in the same latitudes, coming mainly in the summer. It is, in fact, the climate of most parts of China –a modified form of monsoonal climate. It is thus also called the Temperate Monsoon or China Type of climate.
