How Much Do You Know About Earth And Sun?

The Sun is referred to as the source of heat to all planets because it emits vast amounts of energy in the form of heat and light. The Sun's energy is produced through nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of heat and light in the process. This energy radiates outwards from the Sun and reaches all the planets in our solar system, providing the heat necessary for their existence and maintaining their temperatures.

The position of Earth from the Sun is third. This is because Earth is the third planet from the Sun in our solar system. The first planet is Mercury, the second is Venus, and the third is Earth.

Sun aids in photosynthesis in plants. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Sunlight provides the energy needed for this process to occur. It is absorbed by the chlorophyll in plant cells and used to convert carbon dioxide and water into glucose, which is the main source of energy for plants. Oxygen is also released as a byproduct of photosynthesis. Therefore, the correct answer is photosynthesis.

There are seven continents on Earth. Continents are large land masses that are separated by oceans and are the main divisions of the Earth's surface. The seven continents are Africa, Antarctica, Asia, Europe, North America, Australia, and South America. Each continent has its own unique geography, climate, and biodiversity.

The correct answer is Moon because the Moon is Earth's natural satellite. It orbits around the Earth and is the fifth-largest satellite in the solar system. The Moon plays a significant role in Earth's tides and has been a subject of study and exploration by humans for centuries.

The correct answer is Centre. The Sun is located at the center of the solar system. It is a star that all the planets, including Earth, revolve around. The Sun's immense gravitational pull keeps the planets in their orbits and provides heat and light to sustain life on Earth.

The hygrosphere is not an Earth layer. The Earth is composed of several layers including the biosphere, lithosphere, and stratosphere. The biosphere refers to all living organisms on Earth, the lithosphere is the solid outer layer of the Earth, and the stratosphere is the second layer of the Earth's atmosphere. However, the hygrosphere is not a recognized Earth layer.

Xenon is not contained in the Sun. The Sun primarily consists of hydrogen and helium, with small amounts of other elements like oxygen. Xenon, on the other hand, is a noble gas that is not typically found in such massive celestial bodies like the Sun.

Earth has only one natural satellite, which is the Moon. The Moon is Earth's only permanent natural satellite and it orbits around the Earth. It is the fifth-largest natural satellite in the Solar System and is the largest among planetary satellites relative to the size of the planet it orbits.

Earth's axis rotation gives birth to seasons. As the Earth orbits around the Sun, its axis is tilted, causing different parts of the Earth to receive varying amounts of sunlight throughout the year. This tilt, combined with the Earth's rotation, creates the changing seasons. When one hemisphere is tilted towards the Sun, it experiences summer, while the other hemisphere is tilted away and experiences winter. As the Earth continues its orbit, the tilt gradually changes, leading to spring and autumn in between. This cyclic pattern of changing seasons is a result of Earth's axis rotation.
