Explanation:
Homes in Nunavut are often built on platforms to allow air to flow between the house and the frozen ground. It this is not done, the ground may melt and the house will sink into it.
Answer:
The statement is correct.
Explanation:
Nunavut is Canadian territory. It is located in the northern part of the country. It is a territory that is slightly less than half on the mainland, and slightly more than half being composed of islands. The majority of this territory either lies in the Arctic Ocean or has a coastline to it, and a big portion of the territory is in the Arctic circle.
Such location means that Nunavut has a very cold climate, dominated by tundra. The ground is covered with ice for most of the year, and in the short period when the ice melts the soil is muddy and oversaturated with water, thus it is not stable at all. The people had to adapt to these conditions, so they are often building their homes on platforms, thus isolating the house/dwelling from the ice and soil. This is very useful for the stability of the homes, but it causes problems with the heating of them because the air that flows below the house cools it furthermore.

Which option describes how heat and the mobement of Earth's tectonic plates contribute to the formation of an ocean basin?
Heat from the mantle conducts through tectonic plates causing them to melt to form ocean basins.
Heat from the mantle forms convection currents causing the plates to transform and form the ocean basins.
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Heat from the mantle conducts through the tectonic plates causing the plates to converge and form ocean basins.
Answer:
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Explanation:
Ocean basins form as a result of convection in the mantle along divergent margins.
At a divergent margin, new crusts are being formed. It is said to be a constructive margin because new materials reaches through to the earth surface from there. The mantle convection pushes materials up and down away from heating centers and to cold regions and back and forth. This leads to the creation of cells which moves the overlying plate. The mantle materials are then able to reach the surface to form new ocean basin.What is the capital of Punjab

As __________ increases in the atmosphere, global temperatures also increase.
Answer:
1. carbon dioxide-I would say this one
2. methane
Explanation:
It is one of these, technically both, but I think carbon dioxide is the best answer for you.
As Carbon dioxide increases in the atmosphere, global temperatures also increase.
What are the causes of the increase in temperature?The increase in the temperature of the planet is mostly caused by greenhouse gases that are emitted from day-to-day use which disturbs the ecological balance of the planet and results in an increase in temperature.
Deforestation which means cutting trees is also a severe cause of temperature increase as plants absorb the carbon dioxide and produce oxygen but due to deforestation, this process is disturbed.
An increase in the temperature disturbs the ecosystem as higher temperatures lead to the extinction of species due to extremely dry regions which are considered difficult to survive.
Increased ground-level ozone-polluted air, which is produced when air pollution from industries, cars, and other sources reacts with sunshine and heat, makes air pollution much worse as temperatures rise.

It is the most recent of three land eras since complex life advanced, went before by the Mesozoic and Paleozoic. It began with the Cretaceous-Paleogene eradication occasion, when numerous species, including the non-avian dinosaurs, became wiped out in an occasion credited by most specialists to the effect of an enormous space rock or other divine body.

why could it be a disaster for an ecosystem if deers eats lions
it's a disaster
Explanation:
because lions keep the deer population under control and if there are slot of deers then the deeper population would be over crowded and since there are many deers they would have to eat more so most of the grass would be gone and other animals wouldn't have a chance to eat
Answer:
Becasue without lions, the herbivores(plant eaters) will overpopulate. Lions reputation of being the 'chief' predator of their habitat as they are known to even kill/eat herbivores such as elephants and giraffes, which are herbivores. The herbivores will eat a lot of the plants and soon there will be no more plants for the herbivores now because the deer ate the lions. The lions subdue that bye eating deer. That is why deer eating lions would be bad for the ecosystem. If you like my answer please give brainliest. If not, then oh well.

there are greater opportunities for trade in the__than in the__.
A. steppes; major rivers
B. pacific rim; steppes
C. major rivers; pacific rim
D. himalayas: pacific rim
Answer:
There are greater opportunities for trade in the pacific rim than in the steppes.
Explanation:
Trade is something that has been used by humankind for thousands of years. The reason is simple - it is the basis of any economic type, be it primitive, command, market, etc... Basically, through trade, the individuals, groups, countries, regions, get the goods they need in exchange for the goods they have to offer and are needed on the other side.
Not all places on Earth provide the same opportunities for trade though, and in most cases the reason for it is geography. The Pacific Rim, for example, is a huge region and there are countries on all levels of development. It is a region where infrastructure doesn't have much influence because trade goes through water, and even though it is a huge distance in question from one side to another, trade is very easy. On the other hand, we have the steppes. These areas are sparsely populated, are usually low on resources, the climate is harsh, which in turn makes the countries dominated by them are less developed, and that in turn means infrastructure in bad condition or fully lacking in most of the territory. Such conditions result in bad conditions for trade as the opportunities are much lower than in other regions.
