2,069 Questions

Is the sun radioactive?

Yes, the sun emits radiation in the form of light and heat through a process called nuclear fusion. This radiation is not harmful to us on Earth as it is mostly in the form of visible and infrared light.

How does the sun factor into fertile soil?

The sun plays a crucial role in soil fertility by providing energy for photosynthesis in plants. Photosynthesis converts sunlight into glucose, which is used by plants to grow and develop. In addition, sunlight helps regulate soil temperature and moisture levels, creating optimal conditions for soil microorganisms to thrive and breakdown organic matter into nutrients that are essential for plant growth.

Is the Earth made out of soil?

No, the Earth is made up of various layers, including the core, mantle, and crust. Soil is the topmost layer of the Earth's crust, consisting of organic matter, minerals, gases, liquids, and organisms that support plant life.

Is uranium on the sun?

Yes, uranium is present on the sun, but in very small amounts compared to other elements. Uranium is created through nuclear fusion reactions in stars like the sun, but it is not a major component of the sun's composition.

When an organism regulates its internal environment it is?

maintaining homeostasis. Homeostasis is the ability of an organism to regulate its internal environment and maintain a stable, constant condition despite external changes. This process helps organisms to keep optimal conditions for cellular function and overall health.

What is in Sun's soup?

the original soup formula contained shiitake mushrooms (Lentinus edodes), mung bean (Phaseolus aureus), and the Chinese herbs Bai Hua She She Cao (Hedyotis diffusa) and Ban Zhi Lian (Scutellaria barbata).

What is Sun's soup?

Sun's soup is a packaged food product made by Sun Farm Corporation (Milford, Connecticut) that contains vegetables and herbs. The soup's ingredients are said to possess anticancer and immune-building properties.

How is the sun responsible for rain on earth?

The sun plays a crucial role in the water cycle by evaporating water from the Earth's surface, including oceans and lakes. This water vapor rises into the atmosphere, cools, condenses into clouds, and eventually falls back to the Earth as rain due to gravity. Therefore, the sun's heat is what drives the process of evaporation, which leads to rain on Earth.

How is earth's surface heated by the sun?

The Earth's surface is heated by the sun through a process called solar radiation. Sunlight, which consists of energy in the form of electromagnetic waves, reaches the Earth and heats up its surface when it is absorbed by land, water, and other surfaces. This energy is then retained and warms the Earth's surface.

What occurred during the T-tauri Phase of the development of the sun?

During the T Tauri phase, the young sun contracts and increases in temperature, developing strong magnetic fields. This phase is characterized by intense stellar winds and turbulence, leading to the formation of a protoplanetary disk around the sun where planets eventually form.

Are there lanforms on the sun?

The Sun does not have any landforms like mountains or valleys because it is a giant ball of hot gas. It is mostly made up of hydrogen and helium and does not have a solid surface like a planet or a moon.

How does the temperature of a planet vary with distance from the sun?

The distance a planet is from the Sun determines how much solar radiation is receives. Planets that are further receive less and thus are often colder. That is unless their atmospheres trap the energy received from the Sun. This is the case with Venus, which is the hottest planet in the solar system due to its thick atmosphere and runaway greenhouse affect.

Is there any moisture on the moon?

Recent analysis of impact debris from a rocket that was designed to crash into the moons northern polar area show a noteworthy amount of water ice in that region, to the surprise - and delight - of NASA scientists.

How do you know that the sun is bigger than the earth and moon?

Scientists have measured the sizes of the sun, earth, and moon using various methods such as direct observation, mathematical calculations, and comparison of their gravitational effects on other objects. The sun's diameter is about 109 times larger than the earth's and about 400 times larger than the moon's, making it the largest body in our solar system.

Why did Early people had ideas about sun stars or moon on their rituals or customs?

Early people observed the sun, stars, and moon in their daily lives, so these celestial bodies became integral to their rituals and customs as symbols of power, natural cycles, and spiritual connection. They believed that these celestial bodies had influence over their lives and held symbolic significance in various cultural practices and belief systems.

What term is used to describe incoming solar radiation?

  • 25% is absorbed by clouds.
  • 25% is reflected by clouds.
  • 45% is absorbed by the earth's surface.
  • 5% is reflected by the earth's surface.

So 50% reaches the surface of the earth (But 5% of that is reflected).

How are sunquakes and earthquakes similar?

Sunquakes and earthquakes are both seismic events that generate waves. However, sunquakes are caused by disturbances on the surface of the sun, whereas earthquakes are caused by movements along faults in the Earth's crust. Both types of events can produce vibrations that travel through the respective bodies, leading to shaking and the propagation of seismic waves.

Why is the suns energy important to the earth?

it is important because the plants need it to grow, human beings use the solar energy in the sun to slow global warming and some animals eat plants but the carnvores eat animals that eats plants..

How could the earth be destroyed?

The Sun will destroy the Earth.

Nothing to worry about; it won't happen for another 4 BILLION years or so, and we humans will either have become extinct long ago, or moved to other, newer planets around younger suns. Or, perhaps we'll just take the Earth with us and move it into a more distant orbit where it will be safe.

But no matter what we do, the Sun will turn into a red giant star as it depletes its hydrogen fuel. When that happens, the Sun will begin to shrink, and the core temperature and pressure will rise. When the core temperature reaches about 35 million degrees, the Sun will begin fusing helium, greatly increasing the heat output and causing the Sun to expand and heat up.

We expect that the planets Mercury and Venus will be destroyed as the Sun engulfs them. Earth might survive, but in its current orbit would be a burnt cinder in close orbit around a giant star. Either way, all life on Earth will be destroyed - IF we don't move the Earth to a more distant orbit out past Jupiter someplace. By then, we'll almost certainly be able to do so.

How is Earth's surface heated?

The Earth's surface is heated by the Sun's energy. Sunlight contains electromagnetic radiation, which warms the Earth when it is absorbed by the land, oceans, and atmosphere. This energy is then radiated back into the atmosphere, contributing to the Earth's overall temperature.

Does the sun accounts for 75 percent or 99 percent of all the matter in the solar system?

In fact, the Sun accounts for over 99.8% . Most of the rest is contained in Jupiter.

How many days will the sun pass through the zenith in a full year?

If you are located anywhere on earth that's more than 23.5 degrees from the

equator, then the sun can never appear at your zenith.

If you're anywhere within 23.5 degrees of the equator, then the sun will appear

at your zenith, or very close to it, twice each year.

How does the sun tell us there were not living things on the earth billions of years ago?

While planetary science and biological science are not exact, and by no means perfect, it is factual based on what we know and can prove.

That being said, the Earth is approximately 4.6 billion years old. Life on Earth dates back approximately 3.6 billion years to simple cell prokaryotes.

Some might use this to poke holes in evolutionary theory, however, even from a fundamental Christian perspective, evolution and creationism are not mutually exclusive, and there is far more concrete evidence that supports evolutinary science than credible refutation.

Does nuclear fusion occurs at cooler temperatures away from the Sun?

Nuclear fusion generally requires high temperatures and pressure to occur. In the Sun, fusion happens at temperatures of millions of degrees. While researchers are working on developing ways to achieve fusion at cooler temperatures on Earth, current technology requires high temperatures to overcome the repulsion between positively charged atomic nuclei.

How much of the sun's energy does the earth receive?

The Earth receives only a tiny fraction of the Sun's total energy output, about one part in two billion. This energy is essential for driving the planet's climate, weather systems, and supporting life through photosynthesis.
