Q

Describe Mantle

A

Portion of interior below the crust.
Mohorovicic or Moho discontinuity separates the crust above from the mantle below.
Crust and upper part of mantle is called lithosphere. Its thickness ranges from 10-200km.
The upper portion of mantle is called asthenosphere and is the main source of magma.
Its density is higher than crust.
Mantle is in solid state.
Mantle is made up of silicate minerals rich in iron and magnesium.

Q

Lithospheric plates

A

Because the asthenosphere is soft and plastic, the rigid lithosphere can easily move over it.
The lithospheric shell is divided into large pieces called lithospheric plates. A single plate can be as large as a continent and can move independently of the plates that surround it.

There are 7 major and 20 minor types of lithospheric plates

Q

Wegener’s continental drift theory?

A

According to Wegener, all the continents formed a single continental mass called Pangea surrounded by a mega ocean called Panthalassa. Around 20mya in the jurassic period, the super continent, Pangea began to split. pangea first broke into two large continental masses as Laurasia and Gondwanaland forming the northern and southern components respectively which continued to break into various smaller continents that exist today.

He proposed that continents are floating and constantly drifting on the Earth’s surface

His hypotheses later became the basis for plate tectonics

Q

Evidences of existence of Pangaea?

A
  1. Jig-Saw-Fit (The Matching of Continents)- The shorelines of Africa and South America facing each other have a remarkable and unmistakable shore line.
  2. Radiometric dating shows that age of rocks of both the costs of Atlantic are identical. This suggests that the ocean did not exist prior to jurassic age
  3. Palaeoclimatic evidence- The evidences of carboniferous glaciations in the form Tillite rocks are found in Brazil, Falkland, S.Africa, Madagascar, India and Antarctica shows that these landmasses once had the same climate which was possible only if they were contiguous.
  4. paleontological evidence- the distribution of Glossopteris flora too matches with the above contiguous areas of Gondwana land

Q

Plate margins

A

All tectonic activities occur along plate margins

Three types of Plate margins are:
1. Constructive margin or Divergent plate margins or Accreting plate boundaries

  1. Destructive plate margins or Convergent plates or Consuming plate boundaries
  2. Conservative plate margins or Transform Plate movements

Q

Constructive margin or Divergent plate margins

A

Constructive plate margins represent zones of divergence where there is continuous upwelling of lava. The lava spreads on the adjacent ocean floors thus creating new ocean floors

Eg mid oceanic ridges

Q

Destructive plate margins or convergent plates

A

Movement if two plates towards each other, their collision, overriding of one plate by the edge of other plate and subduction and melting of overridden plate margin into the mantle.

The process in which one plate is carried beneath another is called subduction

Q

Ocean-Ocean collision

A

Where oceanic crust lies on either side of a convergent plate boundary, the plate with the denser oceanic crust will subduct below the other plate. The heat and pressure of the mantle melt this sediment, and because it is less dense than the mantle rock, it begins to rise forming island arc -a chain of volcanoes paralleling the subduction trench on the -on the overriding plate

Eg Aleutian, Kuriles, Marianas are jsland arcs

It also forms deep ocean trenches such as Peru-chile trench, Japanese trench

As the subducting plate grinds downward, enormous friction is produced which explains the occurrence of major earthquakes

Q

Ocean-Continent Collision

A

Where oceanic crust collides with continental crust, the oceanic crust which is denser is subducted beneath the less dense continental crust.

Eg- Nazca plate subducts beneath the South American plate
Juan de Fuca beneath North American platr
Pacific plate under Eurasian plate in Japan

This leads to formation of volcanic peaks like Mt. kotopaxi, Mt. Chimborazo of Andes

Rocks can also be squeezed and contorted between colliding plates, becoming uplifted and greatly deformed or metamorphosed. Eg Andes and Rockies

Coconut palm, date palm, and oil palm are found in Africa. Coconut palms are found in the tropical islands and along the equatorial coasts such as Tanzania. They yield Copra from which coconut oil is obtained. Oil palm, from which palm oil is obtained is common in west Africa. Nigeria exports a good deal of this oil. Date palms grows in the oases in the drier regions. Egypt exports a large amount of dates.

Cacao and kola are trees which provide beverages. Cocoa is obtained from cacao which grows well in equatorial lowlands. Ghana and Nigeria export cocoa.
Kola trees yield nuts which are used in preparing cold drinks and chewing gums.

There are three main ranges in the Andes: two of them on the eastern side are very high. These ranges come closer at a few points and separate again. In between these ranges there are high plateaus. The BOLIVIAN PLATEAU is one of them. Lake TITICACA, one of the largest lake is located in this plateau. The Andes have several lofty peaks. Mount ACONCAGUA is the highest peak of the Andes (7,021m). The Andes have several volcanic peaks. COTOPAXI in Ecuador is the highest active volcano is the world.

Q

Climate of Western Europe?

A

Considering its latitude, Europe’s climate is described as mild due to the influence of Westerlies, North Atlantic Drift, relief, and proximity to the seas.
Europe lies in the region of westerlies and wind blows from south-west. Since there is no mountain system from north to south, there is no obstruction for these winds. As a result, these winds blow deeper into the land and modify the temperature. The warm waters of North Atlantic Drift keep the seas along western Europe ice-free. The Westerlies blowing over these currents carry warmth further inland. On their way, they pick up moisture and cause rainfall which is well distributed all through the year. The moderating influence of westerlies and nearness to the seas and oceans keep summers warm and winters cool in western Europe.

187
Q

Climate of Central and Eastern Europe?

A

The moderating influence of the ocean is reduced eastward. As a result, in central and eastern Europe, summers are hot and winters are very cold and rainfall is also less. Such climatic variation is called Continental climate

188

Q

Climate of Northern Europe?

A

The area north of Arctic Circle has an extremely cold climate. Precipitation is very scanty and mostly in the form of snow. Summers are short with long and warm days. The sun is visible even at midnight for a brief period. The land is covered with snow for the major part of the year. It is called Tundra climate

190
Q

Vegetation of Mediterranean region?

282
Q

Explain winters of Asia?

A

In winter, the interior part of Asia becomes extremely cold. Temperature falls below freezing point due to the great distance from the sea. Hence, the air contracts and becomes very dense and heavy, forming high pressure area over Mongolia. Winds blow outward. Since they blow from land, they are dry. As a result, most parts of Asia do not get rain during winter. But while blowing over the sea, these winds pick up moisture and may cause rainfall in some areas.

283
Q

Explain summer of Asia?

A

In summer most of the Asia becomes very hot. As a result, the air expands, becomes light and low pressure areas develop over central Asia and the north-western part of South Asia. By this time, high pressure areas are located over oceans and winds start blowing to these low pressure areas. Thus most of the continent receives rainfall in summer from the moisture-laden winds coming from the ocean.

284
Q

Vegetation of Asia?

A
  1. The northern coast of Asia is the tundra belt.
  2. To the south of tundra is a much broader belt of coniferous forests called the taiga
  3. Temperate grasslands, known as steppes, form the next belt south of taiga.
  4. Large parts of south-west and central Asia are deserts.
  5. South, south-east and east-Asia have monsoon forests.
  6. Extreme southern portion of Asia which are closer to the equator have equatorial rain forests.
