Answer:

The variation of sunlight reaching Earth is one cause of ice ages. .

Explanation:

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age.

When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.

Which of the following types of migration are correctly explained by the example given?
Katena32 [7]

Answer: B. International migration and voluntary migration: Family A from Mumbai has convinced their close friends Family B to emigrate to London as they did in order to help start up their business.

Explanation:

Migration is the process of moving from the place of origin to another area due to personal, social or political reasons. Throughout human history, we have migrated for various reasons, from searching for food, from safer areas to live or exploring new territories, it is part of our nature.

Currently, migration is classified as voluntary or forced migration and internal or international migration.

  • Voluntary migration consists of voluntary internal or international displacement, permanent or temporary, to seek better economic opportunities.
  • Forced migration occurs when the displacement is carried out against the will, due to situations of violence, natural disaster or eviction.
  • Internal migration is what occurs within the same territory, for example from rural to urban areas.
  • International migration consists of movements from the country of origin to another country.

In this case, Family A convinces Family B to make an international migration (from India to England) voluntarily (To establish a business).

Among fossil fuels: Coal is made by heating of woody plant material, and oil is made by heating of algae. Coal is made by heatin
Ivahew [28]

Answer:

Coal is made by heating of woody plant material, and oil is made by heating of algae.

Explanation:

The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.

The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.

The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
