Which list correctly orders the lifecycle of a piece of debris as it passes from space down to earth's surface?
a. meteoroid meteor meteorite
b. meteorite meteor meteoroid
c. meteor meteoroid meteorite
d. meteor meteorite meteoroid

a. meteoroid, meteor, meteorite

Explanation:

The meteoroid, meteor, and meteorite, are terms that very often are mistaken and are used for a single thing, but in practice they are different, despite having the same basis.

All three, as mentioned, have the same basis, they are the same body, just that the differences occur because of the processes through which the space body goes through.

The meteoroid is a term used for the space body while it freely floats into the interstellar space. The meteor is a term used for when the space body enters the Earth's atmosphere and burns, which can actually be seen in the night sky easily. The meteorite is a term that is used for the piece of the space body that managed to reach the surface of the Earth, but more often than not they burn totally and fall apart while passing through the atmosphere, so the meteorites are much rarer than the previous two.

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.
