At the poles, there are no directions. From the North Pole, whichever way we look it is South, and from the South Pole, whichever way we look, it is North. There is no Sunrise or Sunset at the polar regions as we experience at lower latitudes. The Sun appears above the horizon in Summer and makes a 360° circle in the sky - over a period of 187 days at the North Pole 90° North latitude. And in winter, the Sun is below the horizon for 163 days of darkness and 24 days of semi-darkness when the Sun is just below the horizon. It's not exactly six months of darkness/sunlight at the poles. (In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August, and no sunrise between November 14 and January 29.) Needless to mention, when it is summer in the Northern hemisphere, it is winter in the South
Answer:
Answer d is the correct one
Answer:
" Atmospheric instability is critical weather-maker "
Explanation:
- Instability is a condition where the earth's atmosphere is generally considered to be unstable as a result of the weather is subjected to a higher degree of variability over a larger distance and time.
- In metrology, instability is defined by the changes in temperature from the inversion layer in the form of a lapse rate. As the air gets unstable it has two forms as convective and dynamic instability.
- The dynamics are produced by horizontal motion and rest by the vertical motion. It is subject to Coriolis force and pressure gradient force. Thus dynamic lifting and mixing produced the cloud, precipitation, and storms.
- If the unstable atmosphere gets larger it leads to certain problems like dust veils when the winds are light and region of ground instability.
Answer:
1. Neritic Zone
2. Littoral Zone
3. Oceanic Zone
Explanation:
Neritic zone is the region of shallow water approximately 200 meters in depth. The abundance of sunlight and nutrients in this zone, this is most productive zone of the ocean which supports marine life.
Littoral zone is the part of sea which is close to the shore. Organisms in this area are sponges, snails and crabs. It is low tidal zone which is around the shoreline. There aquatic vegetation in this area which is by man made lakes.
Answer:
(D) Indigenous people
Explanation:
Devolution is the process in which the power is delegated from the central ruling government to the lower stances of the authority. This means, local and regional organizations and departments have the power to rule over their own questions and political problems.
<u>Devolution allows groups of indigenous people to have the governance of their communities. </u>In the United States, there is the sovereignty of Native American tribes.<u> This means they have the authority over their regions, tribes, and community, proclaiming them “domestic dependent nations”. </u>Devolution has importance for them as they can own their own land, control their resources and manage local laws.
