Answer:
A. True
Explanation:
Although convection in the asthenosphere is widely accepted as the cause of plate movements, it may be that the weight of down-going lithosphere in subduction zones pulls the trailing plate behind it. This is true because plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move, It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
Answer:
<em>Mantle convective current</em>
<em></em>
Explanation:
The North American Plate is a tectonic plate that covers most of North America, Greenland, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. It is Earth's second largest tectonic plate, behind the Pacific Plate. It is thought to be moved by the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
Answer:
Decline
Explanation:
From the studies that have been done it is expected that the global birth rate will decline after 40 years. There are many reasons for this expectation, some of which are the development of the less developed countries, the people from the villages to move to the cities, more and more people to be out of the poor category, and focusing on careers as the countries develop. Some nations are still expected to have relatively high birthrates, but the majority of the countries will have significant drops in the birth rates, thus the global population will gradually start to slow down its growth, and further in the future stagnate, and probably starting to lower down gradually.
Economic, environmental, and social
Explanation:
Those are the three main pillars
