Which of the following is the solid lower mantle? (3 points) asthenosphere atmosphere lithosphere mesosphere

The correct answer is - Asthenosphere.

The mantle layer is a solid part of the Earth. It lies just bellow the crust, and it is composed of metals. It is a layer that has very high temperature and pressures, as well as strong convection currents.

The astenosphere is the lower part of the mantle, and it is the densest, and most solid of its layers.

This layer of the Earth is estimated to be 2,900 km thick, and it accounts for incredible 84% of the total volume of the planet.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
