Which is biggest between Sun Moon and Earth?
In order of size from largest to smallest
Sun > Earth > Moon.
If we quote the radius of these objects.
Sun ; 695,700 km
Earth ; 6,365 km
Moon ; 1,736 km
From these figures you can see that the Sun is over 100 times bigger than the Earth, and the Earth is nearly 4 times greater than the Moon.
The reason why the Sun and Moon appear to the same size is because the Moon is much nearer to the Earth , than the Sun. It is a property of optics that the further away an object is, then the smaller it appears.
From the Earth;-
Sun's distance is ~92,000,000 miles
Moon's distance is ~242,000 miles.
From the above radii you can calculate the volume of each object. By using the Gravitational Constant the masses of these objects can be calculated.
No, gravity holds planets in orbit around the sun because the sun's gravity pulls on them. This gravitational force between the sun and planets keeps them in their respective orbits. The force between planets themselves is much smaller and mainly affects their interactions with each other rather than their orbits around the sun.
What is really happening when the sun is rising?
The term "the sun is rising" is actually quite mistaken it would work fine for a geocentric model of the solar system (where the Earth was the center of the universe), but not for the heliocentric model of the solar system, because the sun is not doing the moving; it's the Earth.
As the our planet rotates, the part facing the sun is ever changing.
One way to think of it is a ball hanging by a string from the ceiling (representing the Earth), turning slowly. Beside that ball is a lightbulb (the sun). So there is always half of the ball that is in light, and half in darkness; but since it is rotating,There is no place that always stays in light or darkness (there would be if I were to add the tilt, but to keep it simple, I won't). Choosing a point just before it hits the light, visualize how it is moving toward the light, and suddenly it is morning, and though it seems that the sun rises, it's just the Earth turning you to face the sun.
I hope that satisfies

What happens to the energy from the sun that is absorved by earths surface?
The energy from the sun that is absorbed by the Earth's surface is converted into heat. This heat is then re-radiated back into the atmosphere, contributing to the Earth's overall temperature and driving weather patterns and climate systems.
If Earth had such an extreme elliptical orbit, it would face significant challenges for sustaining life. At a million miles from the sun, the planet would suffer from extreme heat, potentially leading to the evaporation of oceans and the destruction of the atmosphere. Conversely, at a light year from the sun, Earth would freeze due to lack of solar radiation, making it uninhabitable.
What happens to trees if they don't get enough sunlight?
If trees don't get enough sunlight, they may have stunted growth, produce fewer leaves, and have a decreased ability to photosynthesize, leading to weakened overall health. This can make them more susceptible to diseases and pests, ultimately impacting their ability to thrive and survive.
a special thing called the receiver and it retrieves the sun
Which part of the Earth receives most of the Sun's energy?
The answer is easy - that part of the Earth where the Sun is DIRECTLY OVERHEAD at mid day.
However, the answer is also complex because this point moves on a daily basis between the latitudes of the Tropic of Capricorn in the southern hemisphere where it is overhead on or around the 21st December the southern "solstice" and the Tropic of Cancer in the northern hemisphere where it is overhead on or around the 21st June the northern "solstice". This movement is caused by the tilt of the Earth's axis of spin by 23° 26′ 16″ to the plane in which the Earth orbits the Sun.
How many days does Pluto's rotation take in earth day's?
One Earth day = 0.15625 Pluto days
In other words, a 24-hr Earth day is about 15% of a Pluto day.
Nearly all of the energy that earth receives from the sun is used in photosynthesis?
While a significant portion of the sun's energy reaching Earth is indeed used for photosynthesis by plants and other organisms, not all of the energy is utilized in this way. Some of it is reflected back into space, absorbed by the atmosphere, or contributes to other natural processes like evaporation and weather patterns.
What is unique about how the Sun rotates around its axis?
The Sun rotates differentially, meaning that different regions rotate at different speeds. Its equator rotates faster than its poles, completing a full rotation in about 25 days, while near its poles, it takes about 35 days for a full rotation to occur.
What are the most important factors affecting the input of solar energy to Earth?
The most important factors affecting the input of solar energy to Earth are the Earth's axial tilt, distance from the sun, and the presence of atmospheric components such as clouds, dust, and greenhouse gases. These factors influence the amount of solar radiation reaching the Earth's surface, which in turn affects climate patterns and overall energy balance on our planet.
Why do birds go to nests during a total eclipse?
Birds may exhibit nesting behavior during a total eclipse due to the decrease in light, which they interpret as the onset of night. This prompts them to return to their nests for shelter and security, as they would during normal nighttime conditions.
What would happen if Earth and Venus followed elliptical orbits around the sun?
Earth and Venus DO follow elliptical orbits around the sun (though the orbit of Venus is only very slightly elliptical). Earth's orbit being elliptical is, combined with our axial tilt, why we have seasons.
When light from the sun warms the ground the transfer of heat energy is called?
The transfer of heat energy from the sun to the ground is called radiation. Radiation occurs when electromagnetic waves, such as light from the sun, transfer energy to the molecules in the ground, causing them to increase in temperature.
This process is known as the greenhouse effect. The Earth's surface absorbs sunlight and re-emits it as heat energy, which gets trapped by greenhouse gases in the atmosphere. This process helps to keep the Earth warm enough to support life.
Is energy from the sun transferred to earth by convection to earth by?
Energy from the sun is primarily transferred to the Earth by radiation, not by convection. Solar radiation travels through the vacuum of space and reaches the Earth in the form of electromagnetic waves. Once it reaches the Earth's atmosphere, it is absorbed and then re-radiated as heat.
What organism makes glucose using energy from the Sun?
Plants, algae, and some bacteria use photosynthesis to convert sunlight into energy to make glucose, which is a form of sugar used for energy storage. This process involves capturing sunlight with chlorophyll and using it to convert carbon dioxide and water into glucose and oxygen.
Who was the first lady in the world land in moon?
No woman has ever landed on the moon. The first and only manned missions to the moon were carried out by male astronauts as part of the Apollo program.
No, the sun will not explode in 2025. The sun is currently in the stable phase of its life cycle known as the main sequence, and it is not expected to undergo a supernova explosion anytime soon. It will eventually evolve into a red giant in about 5 billion years.
What parts of the earth's surface is heated more quickly by the sun during the day?
Surfaces that are lighter in color (such as sand or snow) heat up more quickly because they reflect less sunlight. Additionally, surfaces that are smooth and non-vegetated tend to absorb more sunlight and heat up faster than rough or vegetated surfaces. Areas closer to the equator also receive more direct sunlight and therefore heat up more quickly.
Does the sun play a role in weathering?
Yes, the sun plays a role in weathering through a process called thermal weathering. This occurs when rocks expand and contract due to temperature changes caused by sunlight, leading to their breakdown over time.
What does unbraiding in the sun mean?
Unbraiding in the sun typically refers to taking down braided hair and allowing it to be exposed to sunlight. This can help to naturally soften and enhance the texture of the hair, as well as add highlights or color variations due to the sun's effect on the hair.
