Answer: A. Earth and the Moon share many compositional characteristics
Explanation:
According to the giant impact theory, the Moon formed when an object of the size of Mars and geologically similar to Earth (which was called Theia by scientifics) crashed into the primitive Earth. With this collision, vaporized pieces of the crust of the young Earth were thrown into space. After this, the expelled particles were united by the action of gravity, creating the Moon.
This theory could explain in a certain way the reason why the Moon is predominantly composed of elements similar to those found on Earth, but lighter, making it less dense than Earth, since the material that formed it came from the crust, leaving the rocky core of the planet intact. This was verified by the samples of rocks brought from the Apollo missions, which indicate that it is composed mostly of the same components of the Earth.
They speak French in many areas.
Answer:
Both developed and developing countries have had significant negative impacts on the environment.
Explanation:
The environment has been very badly affected by human activity. The negative effect has been present for a very long time, progressively becoming more and more serious, but since the start of the Industrial Revolution it has exponentially increased and the effects have been horrific. While there are differences between the impact of developed and developing countries, the fact is that both have had significant negative impacts.
The now developed countries were actually the first ones to start with massive impact on the environment, which was a result of the usage of fossil fuels, rapid economic growth, and constantly growing demand for natural resources. The developing countries have started off later with their massive impact, but it has had the same results. While the developed countries are turning a page and try to be as environmentally friendly as possible, that is not the case with the developing countries that try to become developed. To put it simply, The forests that were destroyed in the UK several hundred years ago are not getting back, and the forests that were recently destroyed and still are getting destroyed in Indonesia will not just come back, at least not with the current trends.
