What is gravity?
Read lessGravity is a fundamental force of nature that pulls objects with mass toward one another. It’s what keeps planets orbiting the Sun, makes things fall to the ground, and holds galaxies together. Key Features of Gravity Universal Attraction: Any two objects with mass exert a gravitational pull on eachRead more
Gravity is a fundamental force of nature that pulls objects with mass toward one another. It’s what keeps planets orbiting the Sun, makes things fall to the ground, and holds galaxies together.
Without gravity, there would be no planets, no orbits, and no life as we know it!

Plants make food through a process called photosynthesis, which allows them to convert light energy, usually from the sun, into chemical energy stored in the form of glucose (a type of sugar). This process occurs primarily in the chloroplasts of plant cells, which contain a pigment called chlorophyll that captures light energy.
The overall chemical equation for photosynthesis is:
This means:
Plants make food through photosynthesis, a process in which they use sunlight, water, and carbon dioxide to create glucose for energy and release oxygen as a byproduct. This process is vital for plant survival and for sustaining life on Earth.

The sky appears blue due to a phenomenon known as Rayleigh scattering. This occurs when sunlight passes through Earth’s atmosphere, which contains gases and tiny particles. Sunlight, or white light, is made up of different colors, each with a different wavelength. Blue light has a shorter wavelength and is scattered more easily than colors with longer wavelengths, like red or yellow.
As sunlight interacts with the molecules in the atmosphere, the shorter wavelengths of blue light are scattered in all directions, making the sky look blue to our eyes. This scattering effect is stronger for blue light because of its shorter wavelength compared to other colors in the visible spectrum.
At sunrise and sunset, when the sun is lower in the sky, its light passes through more of Earth’s atmosphere, scattering even more of the shorter wavelengths and allowing the longer wavelengths, like red and orange, to dominate the sky’s color.
