A physical change is change in shape, size, reversible, and change in matter
Answer:
1. Roche limit
2. hydrogen
3. atmosphere
4. Mercury
5. Venus
6. When an object passes the Roche limit, the strength of gravity on the object increases. If the density of the planet is higher, then the object can break up farther away from the planet. If the density is lower, then the Roche limit is located closer to the planet.
7. Farther out in the solar system, beyond the frost line, hydrogen was at a low enough temperature that it could condense. This allowed hydrogen to accumulate under gravity, eventually forming the Jovian planets.
Explanation:
Answer: Precipitation -> evaporation -> condensation
Explanation: precipitation is when it rains, so water is delivered by the atmosphere into the ocean. Evaporation happens when water in the ocean is heated up and returned to the atmosphere. Condensation occurs when water condenses due to pressure/temp differences creating clouds.
Answer: differences in reproducti<span>ve systems
</span>Fat in normal women is between 18% and 20% of body weight, and in normal men it represents 10% to 15%.
Women are ready to nourish a
fetus and then a baby from their own reserves, so women have to stock more
energy and the best way is in the form of fat in anticipation of future pregnancies.
