Who created the modern model of the solar system by discovering that the plantes move in elipses? a. galileo c. ptolemy b. kepler d. copernicus select the best answer from the choices provided

The correct answer is B. Kepler

Explanation:

Johannes Kepler was an important astronomer and mathematician during the 17th century mainly known for his proposals related to the planetary motion that was the base for modern models of the solar system as well as other works such as the theory of universal gravitation by Newton. In his theory, Kepler proposed three main laws that stated the orbit of planets were elliptical rather than perfectly circular, the orbital period dependent on the axis or longest diameter of the orbit and each orbit had two foci. Additionally, this model differs from Copernicus because Copernicus had proposed orbits were circular. Therefore, the astronomer that created the modern model of the solar system and discovered orbits were elliptical was Kepler.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
