Why is the earth called 'blue planet?
Earth is called the "blue planet" because when viewed from space, the planet appears to be predominantly blue due to its abundant water bodies like oceans and seas. Water reflects sunlight and the Earth's atmosphere scatters sunlight in a way that makes the planet appear blue from outer space.
When sunlight strikes earth approximately what percent?
When sunlight strikes Earth, approximately 30% is reflected back into space by clouds, atmospheric particles, and the Earth's surface. The remaining 70% is absorbed by the atmosphere, oceans, and land, which helps to drive the planet's climate and weather systems. This balance is crucial for maintaining life on Earth.
How does the sun reflect?
The sun does not reflect as it is a source of light itself. However, objects in space or on Earth can reflect sunlight by bouncing the light off their surfaces, like the Moon reflecting sunlight back to Earth.
Why weren't the ten smaller moons discovered until a space probe passed by uranus?
The ten smaller moons of Uranus were not discovered until a space probe passed by because they are relatively small and faint, making them difficult to detect from Earth due to the planet's distance and brightness. The space probe was able to capture clear images and data from close proximity, allowing scientists to identify these smaller moons orbiting Uranus.
Why does some of the suns energy reflect back into space?
Some of the sun's energy reflects back into space because of the Earth's atmosphere and surface. When sunlight hits the Earth, some of it is absorbed by clouds, atmospheric gases, ice, snow, and the Earth's surface, and then reflected back into space. This phenomenon is known as albedo.
Why is it important to us on Earth that light can travel through space?
It is because light can travel through space that Earth can get sunlight. Without sunlight life on Earth could not exist.
Does all sunlight energy stay on Earth?
Sunlight also gets reflected back out into space.
Why is sunlight more dangerous in space than on earth?
Sunlight is more dangerous in outer space than on Earth because there is no matter in space, unlike on Earth, so sunlight just passes through the emptiness of space and shines in all directions. When light passes through matter, it takes longer for the light to pass through it to reach something. In space, it only takes 8 minutes for sunlight to reach Earth's surface. The speed of light also depends on what type of matter the light is going through.the sun is more hotter in space than the earth
Why earth looks blue in colour from space?
The Earth appears blue from space due to the way that sunlight is scattered and absorbed by the Earth's atmosphere and surface. The blue color comes from the scattering of sunlight by air molecules, and the reflection of sunlight by the oceans and other bodies of water.

Why does Earth look blue from space?
Earth looks blue from space because of the way sunlight interacts with our atmosphere. The Earth's atmosphere scatters sunlight in all directions, but blue light is scattered more than other colors because it has a shorter wavelength. This scattering of blue light gives the Earth a blue appearance when viewed from space.
What percent of sunlight makes it to Earth's surface?
Roughly 30% of sunlight is reflected back into space by clouds and particles in the atmosphere, while the remaining 70% reaches the Earth's surface.
About how far does sunlight travel through space before it reaches the Earth?
150 million km.
Where can you find nonrenewable resources?
Some renewable resources, such as sunlight or wind, can be found anywhere on Earth. Actually, sunlight can even be found in outer space (which is why the international space station uses solar panels for power).
What percent of incoming sunlight is absorbed by earth surface?
About 70% of incoming sunlight is absorbed by Earth's surface, primarily by land, oceans, and vegetation. The remainder is reflected back into space by clouds, aerosols, and ice, contributing to Earth's energy balance.
What are three things that reflect light in space?
Planets: Bodies in space that reflect light from a nearby star, such as the Earth reflecting sunlight. Moons: Natural satellites that reflect light from their parent planet or from the sun, like Earth's moon reflecting sunlight. Asteroids: Rocky or metallic objects in space that can reflect sunlight if they are large enough and have a shiny surface.
Why does earth look like a blue marble?
Earth appears blue from space because of its oceans, which cover about 71% of its surface. This vast amount of water reflects and scatters sunlight, giving the planet its characteristic blue appearance. Additionally, the Earth's atmosphere also scatters sunlight, which further contributes to the blue hue when viewed from space.
