Answer:
Terrestrial planets
Explanation:
There are two types of planets:
- The inner planets or terrestrial planets
- The outer planets or Jovian planets.
The outer planets are gas giants and are made of huge mounds of gases. These planets are Jupiter, Neptune, Uranus and Saturn. They all have satellites revolving round them.
The terrestrial planets are small rock masses. They are mercury, venus, earth and mars. Earth has one satellites and Mars has two satellites.
The asteroid belt seperates the Jovian and terrestrial planets. Beyond the Jovian planets lies the Kuiper Belt Objects or KBOs.
Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.

Answer:
A. The ice has a high albedo.
Explanation:
Albedo is a measure of ‘whiteness’ or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.
