Venus is hotter than Mercury due to its thick atmosphere, which is rich in carbon dioxide. This atmosphere traps heat through the greenhouse effect, causing surface temperatures to soar despite being farther from the Sun.

The Sun and the Moon are not the same size. The Sun is about 400 times larger in diameter than the Moon. However, due to their distances from Earth, they appear similar in size during a solar eclipse.
The Sun shines during the day because it is the primary source of light for Earth. The Moon shines at night by reflecting sunlight, which makes it visible when the Sun is not illuminating the sky.
Stars appear to twinkle due to atmospheric turbulence. As starlight passes through layers of Earth’s atmosphere, varying air densities cause refraction, leading to fluctuations in brightness and position, creating the twinkling effect known as “stellar scintillation.”
The Hubble Space Telescope is named after the American astronomer Edwin Hubble. It is used to observe distant galaxies, stars and other celestial phenomena, providing valuable data that has advanced our understanding of the universe.
Mars has two moons named Phobos and Deimos. Phobos is the larger and closer moon, while Deimos is smaller and more distant. Both moons are irregularly shaped and believed to be captured asteroids.
Earth can be considered a satellite of the Sun because it orbits the Sun due to gravitational attraction. This relationship is similar to how moons orbit planets, demonstrating the dynamic interactions within the Solar System.
The average distance between the Earth and the Moon is approximately 384,000 kilometers (238,855 miles). This distance can vary due to the Moon’s elliptical orbit, ranging from about 363,300 km to 405,500 km.
The image illustrates the process of evaporation followed by condensation. The steam from boiling water rises and, when cooled, it condenses into liquid form. This method is used in separation techniques like distillation for purifying water.
Yes, you can obtain both salt and water by using evaporation. Heating the saltwater solution allows the water to evaporate, leaving the salt behind as a solid, which can then be collected.
