What makes Earth capable of supporting life?

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.

What are four conditions earth needs to support life?

Life as we know it requires biogenic elements, a source of energy, liquid water, and a suitable, reasonably stable environment for evolution to take place.

How does Earth Support Life Class 6?

(b) The term Solar System refers to the “family” of the Sun. The Sun is a star around which eight planets, among other celestial objects, revolve in orbits. This whole system of bodies is called the Solar System. The Sun is the “head” of this system.

Would Earth be able to sustain life if one of the spheres is not present?

Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of air temperature between the land and oceans). Without the atmosphere (giving us air to breathe and protection from incoming solar rays), there would be no life on Earth.

Why is the size of the earth important?

Typically, the more massive the planet, the more massive the atmosphere it can acquire and maintain. This is important because the mass of a planet’s atmosphere will directly influence its climate. A more massive planet, with a more massive atmosphere, will likely have a stronger greenhouse effect.

How does diameter affect gravity?

The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses. The gravitational force is extremely hard to detect unless at least one of the objects has a lot of mass.

How does the atmosphere sustain life on Earth?

Earth’s atmosphere is composed of about 78\% nitrogen, 21\% oxygen, and one percent other gases. 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.

What is the true shape of the Earth Class 6?

geoid-earth like shape
Answers: (a) The true shape of the Earth is geoid-earth like shape. In other words, it is orange shaped.

Why is the Earth able to support life?

Answer Wiki. Earth is able to support life because it is in the habitable zone, also known as the goldilocks zone around our star, the sun. This means that it can is far enough away from the sun that water won’t burn up and evaporate, and it’s close enough so that water won’t freeze into ice. Water is necessary for life to emerge.

How does a planet’s size affect its ability to sustain life?

Without sufficient mass a planet won’t have enough gravity to hold onto its water. A new study tries to understand how size affects the ability of a planet to hold onto its water, and as a result, its habitability. The issue of what might make a planet habitable is an ongoing debate.

What would happen to the Earth if it became smaller?

Imagine Earth becomes smaller, while keeping the same composition. It has less ans less atmosphere and oceans, but other problems occur before: being smaller, at a moment it cooled faster and lost its magnetic field, allowing sun radiation to stripe out the atmosphere.

What is the importance of the core of the Earth?

Earth’s core provides a source of geothermal heat and energy as well as generating a magnetic field that protects Earth from solar storms. Earth also gains protection from its atmosphere, which keeps out excessive radiation. Finally, Earth has water. Besides being vital to life on Earth now,…
