Answer:
Heavy bombardment, solar wind, condensation, frost line, planetesimal, accretion, solar nebula, radiometric dating
Explanation:
The first few hundred million years of the solar system 19s history were the time of the <u>heavy bombardment</u>, during which Earth suffered many large impacts.
The era of planet formation ended when the remaining hydrogen and helium gas of the solar nebula was swept into interstellar space by the <u>solar wind</u>.
Ice can form from a gas through the process of <u>condensation</u>.
Hydrogen compounds in the solar system can condense into ices only beyond <u>frost line</u>.
Our Moon was most likely formed by a collision between Earth and a Mars-sized <u>planetesimal</u>.
Mars was formed by the <u>accretion</u> of smaller objects.
Our solar system was created by the gravitational collapse of the <u>solar nebula</u>.
<u>Radiometric dating</u> allows us to determine the age of a solid rock.
answer
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour
The answer is b an astronomical unit
The region that was hit the hardest by the bubonic plague in the 1300's was the Mediterranean region.
Big portions of Europe had big losses when this disease came to the European soil, but the Mediterranean region, on European, Asian, and African soil, was hit the hardest and had the biggest losses in human lives. The body didn't had a defense system for this disease nor do the medics of the period had a solution for it, so once someone got it, it meant that the person is destined to die in a matter of days.
