How has the Sun made life possible for life on Earth?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
What is the relationship between the Sun and life on Earth?
Astronomy, Biology, Earth Science, Physics The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.
Why do you think Earth’s distance from the Sun makes life on Earth possible?
It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Is life on the Sun possible?
Potential for Life The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun's light and energy.
What role the sun played in the origin of life?
Before life began, radiation from the sun was the primary source of energy on our planet, just as it is today. In this oxygen-poor, prebiotic world, solar energy may have provided the jolt to transform simple organic molecules into more complex ones, which were used as the building blocks of biology and life.
What would happen without the sun?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.
What is the relationship between the Sun and?
Sun gives heat and light to earth. Earth orbits sun in 365.242 days. THis orbital motion makes seasons along with axial tilt of Earth.. Suns heat makes clouds making rains.so most places on earth gets water and plants survive.
Which of the following is true about the Earth’s relationship to the Sun quizlet?
Which of the following is true about the earth's relationship to the sun? The seasons are caused by the tilt of the earth on its axis as it revolves around the sun. A climax community reaches a peak phase of growth and then, as part of its cycle, dies.
What makes life on the Earth possible quizlet?
What makes life on the Earth possible? The balance between the biosphere, geosphere, hydrosphere, and atmosphere make life on Earth possible. Each component of the Earth system interacts with the others to exchange matter and make life possible.
What makes life possible?
Earth's amazing gaseous atmosphere is responsible for making life possible on this, the third planet from the Sun. Our atmosphere contains water vapor which helps to moderate our daily temperatures. Our atmosphere contains 21% oxygen, which is necessary for us to breathe, 78% nitrogen, and . 9% argon.
Could anything survive on the sun?
Of all the bodies in our solar system, the sun is probably the one we want to give the widest berth. It gushes radiation, and even though its surface is the coolest part of the star, it burns at about 9,940°F, hot enough to incinerate just about any material.
What would life be on Earth without the sun?
Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
What role does the sun play in this process?
The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds… clouds that move over the globe and drop rain and snow. This process is a large part of the water cycle.
What is the work done by the sun on the Earth?
zero It is always zero as force acting between earth and sun is the centriptal force and made angle of 90 degree and the value of cos 90 = 0. work done by the sun is zero.
Is life possible without the sun?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth's position in the solar system is optimal for the development of life.
What if the sun disappeared for 5 seconds?

How does the Earth Sun relationship affect climate?
The Earth's climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall.
What is true about the Earth’s orbit around the sun?
Rather than being a perfect circle, the Earth moves around the Sun in an extended circular or oval pattern. This is what is known as an "elliptical" orbit. This orbital pattern was first described by Johannes Kepler, a German mathematician and astronomer, in his seminal work Astronomia nova (New Astronomy).
How much of the Earth’s energy comes from the sun?
100% of the energy entering earth's atmosphere comes from the sun. ~50% of the incoming energy is absorbed by the earth's surface i.e. the land and oceans.
Why do scientists study the characteristics that make life on earth possible?
Why do scientists study the characteristics that make life on Earth possible? To know what life supporting conditions to look for on other planets.
Which is one way that Earth’s atmosphere supports life?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
What are the 4 factors that allow for Earth to support life?
It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements. These are listed in Table 1 along with the occurrence of these factors in the Solar System (2).
Can life exist without the sun?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth's position in the solar system is optimal for the development of life.
Can life live without the sun?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth's position in the solar system is optimal for the development of life.
What happens if the sun dies?
Once all the helium disappears, the forces of gravity will take over, and the sun will shrink into a white dwarf. All the outer material will dissipate, leaving behind a planetary nebula. "When a star dies, it ejects a mass of gas and dust — known as its envelope — into space.
What is the work done by the sun on the earth?
zero It is always zero as force acting between earth and sun is the centriptal force and made angle of 90 degree and the value of cos 90 = 0. work done by the sun is zero.
Why is sunlight very important to the ecosystem?
The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth's atmosphere. Light intensity controls plant growth.
What would be the result if earth does not revolve around sun?
In other words, anything on the Earth's leading side would fly off into space, continuing along the Earth's orbital path around the sun. Anything on the trailing side would be pulverized against the Earth. It would be a horrible, gooey mess.
Why does the work done on the Earth due to the gravitational force of the sun equal to zero?
Answer: Work done is equal to zero assuming earth revolves around the sun in a perfect circle.
