Static Quiz 31 October 2022 (Geography)

Solution: B
Justification: The climate of Western Europe is a marine climate. Its abundant moisture comes from the Atlantic Ocean. The ocean moderates the temperature during the seasons, making the winter moist and mild, and the summer moist and cool. This climate primarily stays to the north of the Alps, thus considering the Alps a climatic divide.
Statement 1: It is under the influence of westerlies throughout the year.
Statement 2: The relatively warm waters of the North Atlantic Drift are responsible for moderating the climate of Western Europe, so that winters are less cold than would otherwise be expected at its latitude.

Solution: A
Justification: The pre-dominant vegetation of this Siberian “sub-Arctic” type of climate is evergreen coniferous forest. It stretches in a great, continuous belt across North America, Europe and Asia. The greatest single band of coniferous forest is the Taiga in Siberia. There are small patches of coniferous forests in European countries like Germany due to the high altitude.

Solution: A
Justification: This is so because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land. The movement of sea and land breeze helps to moderate the climate. On the other hand, where in Northern hemisphere there is more land, temperatures reach both extremes, for e.g. in Central Asia or Siberia.
Statement 2: Photoperiodism is related to plants reaction to light, it isn’t relevant here.

Solution: D
Justification: Statement 1: Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses. Glaciers form when snow remains in one location long enough to transform into ice. Statement 2: Presently, glaciers occupy about 10 percent of the world’s total land area, with most located in
Polar Regions like Antarctica, Greenland, and the Canadian Arctic. On Earth, 99% of glacial ice is contained within vast ice sheets in the Polar Regions, but glaciers may be found in mountain ranges on every continent including Oceania’s high-latitude oceanic islands such as New Zealand and Papua New Guinea.
Statement 3: Many glaciers from temperate, alpine and seasonal polar climates store water as ice during the colder seasons and release it later in the form of meltwater as warmer summer temperatures cause the glacier to melt, creating a water source that is especially important for plants, animals and human uses when other sources may be scant. Within the past 750,000 years, scientists know that there have been eight Ice Age cycles, separated by warmer periods called interglacial periods. Currently, the Earth is nearing the end of an interglacial, meaning that another Ice Age is due in a few thousand years. This is part of the normal climate variation cycle. Scientists still have many questions to answer about climate change. Although glaciers change very slowly over long periods, they may provide important global climate change signals.

Solution: D
Justification: Global sea level trends and relative sea-level trends are different measurements. Just as the surface of the Earth is not flat, the surface of the ocean is also not flat — in other words, the sea surface is not changing at the same rate at all points around the globe. Sea level rise at specific locations may be more or less than the global average due to many local factors: subsidence, ocean currents, variations in land height, and whether the land is still rebounding from the compressive weight of Ice Age glaciers. Sea level is primarily measured using tide stations and satellite laser altimeters.
