1. As of right now, our solar system only includes asteroids and they are found in Kuiper Belt next to Saturn.
On May 6, 2020, scientists have discovered a mysterious blanket of darkness approximately 1,000 light years away from our solar system. However, in this case, black holes would not be a correct answer.
Even though constellations may seem close, they are actually far away since the size of the stars are immense and can be visible from light years away. Constellations are not in our solar system.
Galaxies are groups of solar systems so therefore galaxies is not an answer.
2. Ptolemy was the man who proposed the early Earth-centered model of the universe and his model was called the Ptolemaic model also known as the geocentric model.
3. The planet that is most similar to Earth in mass and diameter is Venus.
4. The inner planets in our solar system are formed from dense elements and that is why they are able to withstand the intense of the sun. Meanwhile the outer planets were formed from gaseous materials but Pluto is so cold that its elements are hardened and dense.
5. The answer would be D since they orbit in the same direction and on the same plane.
6. The speed of rotation determines the length and duration of day on a planet.
7. The answer would be D since they have to have their own gravity, have a path clear of smaller bodies , and orbit a star,
Answer 1) : Hydrosphere.
Explanation : The largest sphere on the planet is hydrosphere, which is the combined mass of water found on a planet, available under, and above the surface of a planet, minor planet or natural satellite. It has been estimated that there are 1,386 million cubic kilometers of water on Earth. So, this is the largest sphere on a planet if you are traveling on Earth.
Answer 2) The other parts of the sphere are geosphere, atmosphere and biosphere.
Explanation : Geosphere - This sphere includes all the stuff that make up the crust and the core of the earth. It includes everything natural and lifeless that make up the surface of the earth. Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans.
Atmosphere - The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.
Biosphere - It is also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system, and largely self-regulating.
Refer to the diagram shown below.
Define unit vectors along the x and y axes as respectively
Then the three successive displacements, written in component form, are respectively
The total displacement for the first leg of the trip is

Answer:
The process of crystal forming is called crystallization. Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. In nature, crystals can form when liquid rock, called magma, cools.
