![Re-order the numbers so the events occur in the correct order, with the oldest event as number 2, and
the youngest event as number 13.
2. Now at roughly 100% of present-day mass and the asteroid bombardment over, Earth begins
cooling and differentiating. As the outer layer of the Earth cools and solidifies, lighter elements
and compounds rise to the surface while the denser ones sink to the core

asteroids from gravity

A Mars-sized protoplanet we call Theia collides with primitive Earth, adding even more energy

5. The Big Bang
6. As the early atmosphere cools, water vapor is eventually cool enough to condense into liquid
water, eventually covering the planet in an ocean
7. The debris from the collision of Earth and Theia produce a ring in orbit. This ring eventually
coalesces into the Moon, just as Earth coalesced from the solar accretion disc

- 4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…arrow_forwardWhy is the composition of a comet typically dominated by volatile materials (frozen ices)? choose one of the following: a. rock and metal could not condense out of the solar nebula at extreme distances from the sun b. most of the metal in the solar system is locked up inside the terrestrial planets c. metals are not stable in the outer solar system d. elements that form ices (as opposed to rock & metals) are more abundant in our solar systemarrow_forwardIf the velocity of the Solar Wind about 4.0 x 10^2 km/s and the visible tail of a comet of 9.0 x 10^8 km long, how many days does an atom in the solar wind take to travel from the nucleus to the end of the visible tail?

- If you stood on Earth during its formation, during which it captured about 1.6 ✕ 1011 particles per second, and watched a region covering 170 m2, how many impacts would you expect to see in an hour?

How many comets would have to strike Earth in order to account for the roughly 2×1021 kg of water presently found on our planet? (Hint: simple division) If this amount of water accumulated over a period of 500 million years, how frequently must Earth have been hit by comets during that time?
