THINK AND ANSWER

Why is London at 51°N not so cold in winter as New York at 41°N ?
Answer:
Ans. In the winter, London is wanned by prevailing winds from the south west, warmed by warm water from the Caribbean by the gulf stream, whilst new york has a more continental winter.

Discuss

Discuss the importance of ocean currents and winds for the climate of Europe.
Answer:
Ocean currents : The warm North Atlantic Drift helps to keep parts of western Europe warm. The ports here are open for trade even in winter.
Winds : The South-Westerlies that blow across the North Atlantic Ocean towards Europe are warmed as they pass over the North Atlantic Drift. These warm winds from sea to land pick up moisture and cause rainfall, which decreases eastwards. They also help to raise the winter temperatures of coastal and central European countries.

D. Answer the following questions in brief.

Question 1.
How does the climate of Europe change from :

(a) east to west
(b) north to south

Answer:

(a) east to west — Winters and summers are more severe in the east than in the west. The annual rainfall is highest in the west and decreases steadily eastwards.
(b) north to south — North European countries experience longer, colder winters and shorter, cooler summers than south European countries.

Question 2.
List the factors that affect the climate of Europe.
Answer:
Factors Affecting the Climate of Europe :
Latitude — Most of Europe lies within the temperate latitudes, which are neither too hot nor too cold. Only a small part of the continent lies north of the Arctic Circle in the frigid zone.
Nearness to Water Bodies — Except for eastern Europe, all other parts of Europe are close to the sea. There are oceans, seas, bays, gulfs, straits, and even lakes which have a moderating effect on the climate.
Relief Features — The east-west arrangement of most highlands, especially the Alps, allows the rain-bearing winds to enter places in the interior and cause rainfall there.
Ocean Currents — The warm North Atlantic Drift helps to keep parts of western Europe warm. The ports here are open for trade even in winter.
Winds — The South-Westerlies that blow across the North Atlantic Ocean towards Europe are warmed as they pass over the North Atlantic Drift. These warm winds from sea to land pick up moisture and cause rainfall, which decreases eastwards. They also help to raise the winter temperatures of coastal and central European countries.

Question 3.
How is the vegetation of the Mediaterranean region able to withstand the summer drought conditions ?
Answer:
Mediterranean Vegetaion: The vegetation which consists mainly of trees with thick spongy barks and leaves, and long roots as well as shrubs and bushes with small, waxy leaves and thorns. The long roots, small waxy leaves, and thick spongy bark help the trees survive in dry summers.

Question 4.
What changes have human beings brought about in the temperate grasslands of Europe ?
Answer:
As large parts of the forest of this region was cutted down and now used for the cultivation of wheat and other cereals. As land development drives animal away from populated areas and changes the condition of environment.

Question 5.
Name a few minerals found in large quantities in Europe.
Answer:
Europe has fairly large deposits of iron ore, coal, petroleum, natural gas, bauxite, zinc, copper, lead, nickel, and manganese.

E. Answer the following questions in one or two paragraphs.

Question 1.
Explain how relief features, winds, and ocean currents affect the climate of Europe.
Answer:
The following factors affect the climate of europe:
Latitude — Most of Europe lies within the temperate latitudes, which are neither too hot nor too cold. Only a small part of the continent lies north of the Arctic Circle in the frigid zone.
Nearness to Water Bodies — Except for eastern Europe, all other parts of Europe are close to the sea. There are oceans, seas, bays, gulfs, straits, and even lakes which have a moderating effect on the climate.
Relief Features — The east-west arrangement of most highlands, especially the Alps, allows the rain-bearing winds to enter places in the interior and cause rainfall there.
Ocean Currents —The warm North Atlantic Drift helps to keep parts of western Europe warm. The ports here are open for trade even in winter.
Winds — The South-Westerlies that blow across the North Atlantic Ocean towards Europe are warmed as they pass over the North Atlantic Drift. These warm winds from sea to land pick up moisture and cause rainfall, which decreases eastwards. They also help to raise the winter temperatures of coastal and central European countries.

Question 2.
What is the difference between maritime and continental climates ?
Answer:
Continental climate :
As the name suggests, this climate is experienced in the eastern parts of Finland, Poland, Russia, the Baltic states, the Czech Republic, and Slovakia. Great variations in summer and winter temperatures and low amount of summer rainfall are features of this type of climate. Thus, it is also called the continental climate.
Mediterranean Climate :
As the name indicate, this climate is mainly experienced in the regions bordering the Atlantic Ocean. Since these regions are near the sea, they have warm summers and cool winters, with rainfall through – out the year.

Question 3.
With the help of two examples from Europe, show how the vegetation of Europe is closely related to climate.
Answer:
Though a small continent, Europe has a great variation of climate. The main types of climates are Arctic and Sub-Arctic, west European or maritime, central European, east European, desert, and Mediterranean climates.
The main vegetation types of Europe include tundra vegetation, taiga or coniferous vegetation, mixed vegetation, temperate grasslands or the steppes, and Mediterranean vegetation.

Question 4.
What do the terms ‘tundra’, ‘taiga’, and ‘steppes’ refer to ? Explain each of the terms and state where each is found.
Answer:
Tundra : A vast, flat, treeless Arctic region of Europe, Asia and North America in which the sub soil is permanently frozen.
Taiga : Taiga is the largest terrestrail biome on earth: It extends in a broad band across Europe, North America and Asia to the Southern border of the arctic tundra.
Steppes : A large area of flat unforested grassland in South¬East Europe or Siberia.

Question 5.
How has the wildlife of the tundra adapted to the climate?
Answer:
The wildlife of tundra specially reindeer has wonderfully adopted to the extreme cold. Its thick hair protects it from the cold. Its long, flat hoofs are suited for walking over snow and for digging in the snow to look for buried vegetation.

Question 6.
Why has the area under forest in Europe dropped from 80 per cent to 30 per cent in recent years ?
Answer:
The area under forest in Europe dropped from 80 per cent to 30 per cent in recent years because of cutting down of trees to make and available for cultivation and industries as the continent has high population density. Today there are only three main forested areas—the Scandinavian mountain region, the Alpine mountain region, and the taiga region of Russia. A few mixed forests and Mediterranean forests are also found in southern Europe.
