Kepler correctly proposed that the planets orbited the sun in orbits. a. circular c. linear b. elliptical d. spherical

The correct answer is B. Elliptical

Explanation:

Johannes Kepler was one of the most important astronomers during the scientific revolution that took place in the 17th century. Kepler is mainly recognized due to his proposals about the motion of planets that he registered in books such as the Astronomia nova. One of the most important ideas of Kepler was that planets orbited the sun in elliptical orbits, rather than in circular orbits as it was believed before Kepler's proposal. Additionally, Kepler got to this conclusion based on observations and models that prove orbits could not be circular. Thus, Kepler correctly proposed that the planets orbited the sun in elliptical orbits.

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.
