Answer:
The outer planets are also called gas giants; The outer planets have a high gravity due to their large size; The outer planets formed where temperatures were cooler
Explanation:
All planets in our solar system can be divided into two groups; inner and outer planets. Border between these two groups is the asteroid belt. So, all the planets further from the asteroid belt ( Jupiter, Saturn, Uranus and Saturn) are called outer planets. They all have some characteristics in common:
- they are huge in size, several times bigger than the Earth, and since they are mostly composed of gases they are referred to as "gas giants"
- since the gravity of a planet is directly proportional to its size, these planets have higher gravity, which is why outer planets have multiple moons and rings
- since they are very far from the heat source, the Sun, they were formed in a cold part of space and their temperature is lower
Although Pluto also is further from the asteroid belt, it does not fulfill all the criteria to be a planet; officially, its status is a dwarf planet.

Answer:
Correct answer is C.
The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred.
Explanation:
A black hole is a giant, gaseous and huge structure present in the space.In physical appearance, it ca be 29 times more massive and bulky than the sun. The black hole pulls energy and matter from the surrounding galaxies and is becoming enormous in size day by day.
Moreover, a black hole pulls light from its surrounding matter with so much gravity that it gets trapped and can not escape from it. Stellar is a kind of black hole which emerges when a big star collapses or falls in automatically. When it occurs an exploding star "supernova" is formed which bursts out into an explosion.
<span>The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 75% of the atmosphere's mass and 99% of its water vapour and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes. It is deeper in the tropics, up to 20 km, and shallower near the polar regions, approximately 7 km in winter. The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer. This layer is typically a few hundred meters to 2 km deep depending on the landform and time of day. The border between the troposphere and stratosphere, called the tropopause, is a temperature inversion.</span>
