Which of the following planets are very cold and are called ice giants...
Answer:
Introduction:
Ice giants are a category of planets in our solar system that are characterized by their extremely low temperatures and predominantly composed of icy substances. These planets are located at a significant distance from the Sun, which results in their cold temperatures. Among the planets in our solar system, Uranus and Neptune are classified as ice giants.
Main Explanation:
The correct answer to the question is option 'C,' which states that Uranus and Neptune are the ice giants in our solar system. Let's understand why this is the case.
1. Uranus:
- Uranus is the seventh planet from the Sun and is known for its striking blue-green color.
- It is classified as an ice giant because a significant portion of its composition consists of icy materials such as water, ammonia, and methane.
- The average temperature of Uranus is around -224 degrees Celsius (-371 degrees Fahrenheit), making it one of the coldest planets in our solar system.
2. Neptune:
- Neptune is the eighth and farthest planet from the Sun.
- Like Uranus, Neptune is also classified as an ice giant due to its composition, which includes a large amount of ice and other volatile substances.
- Neptune's average temperature is approximately -218 degrees Celsius (-360 degrees Fahrenheit), making it extremely cold.
3. Other options:
- Saturn: While Saturn is a gas giant, it is not classified as an ice giant. Its composition primarily consists of hydrogen and helium, with smaller amounts of other substances.
- Mercury: Mercury is the closest planet to the Sun and is known for its scorching temperatures. It cannot be classified as an ice giant due to its proximity to the Sun and lack of icy composition.
- Earth: Earth is a terrestrial planet and is not an ice giant. It has a diverse composition, including a solid crust, mantle, and core, with a relatively moderate temperature range suitable for supporting life.
Conclusion:
In conclusion, the planets Uranus and Neptune are classified as ice giants due to their predominantly icy compositions and extremely cold temperatures. Saturn, Mercury, and Earth do not fit the criteria for being ice giants.
