What is the major factor controlling weather?

What is the major factor controlling weather?

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

Where does the sun’s energy come from quizlet?

The sun’s energy comes from the burning (combustion) of hydrogen like a huge fire.

Which of these is the source of the sun’s energy?


What was the source of the sun’s energy postulated by nineteenth century scientists quizlet?

Radioactive decay

How is quantum tunneling important to our existence here on earth?

How is quantum tunneling important to our existence here on Earth? A. It plays a crucial role in nuclear fusion in the Sun, so that our Sun would not shine brightly without it. It explains how neutron stars are able to stay stable rather than collapsing under their strong gravity.

Why is our sun not collapsing?

It is only because the inner parts of the Sun are hotter that the Sun doesn’t collapse under its own gravity. The force which they exert is described by the pressure; the internal pressure is higher than the external pressure, so the Sun is held up against gravitational collapse.

How long can humans live?

79 years

How long will sun last?

five billion years

Which is older sun or Earth?

One grain is more than 3 billion years older than the Sun, which, at more than 7 billion years, makes it the oldest solid material on Earth. These results were published in Proceedings of the National Academy of Sciences of the United States of America on 13 January.

Is there life on the sun?

The Sun itself is not a good place for living things, with its hot, energetic mix of gases and plasma. But the Sun has made life on Earth possible, providing warmth as well as energy that organisms like plants use to form the basis of many food chains.

What is our sun’s name?

Although it’s a star – and our local star at that – our sun doesn’t have a generally accepted and unique proper name in English. We English speakers always just call it the sun. You sometimes hear English-speakers use the name Sol for our sun.

What killed life on Mars?

After mapping cosmic radiation levels at various depths on Mars, researchers have concluded that over time, any life within the first several meters of the planet’s surface would be killed by lethal doses of cosmic radiation.

Is Viking 1 still on Mars?

Viking Orbiter 1 continued for four years and 1,489 orbits of Mars, concluding its mission August 7, 1980, while Viking Orbiter 2 functioned until July 25, 1978. Viking Lander 1 made its final transmission to Earth November 11, 1982. The last data from Viking Lander 2 arrived at Earth on April 11, 1980.

Where is Viking 1 and 2 now?

Each orbiter-lander pair flew together and entered Mars orbit; the landers then separated and descended to the planet’s surface. The Viking 1 lander touched down on the western slope of Chryse Planitia (the Plains of Gold), while the Viking 2 lander settled down at Utopia Planitia.

How much did Viking 1 cost?

1 billion USD (1970)

What was first landing on Mars?

The first successful landing on Mars came on July 20, 1976, when NASA’s Viking 1 lander touched down in Chryse Planitia (The Plains of Golf). The massive 1,270-lb (576-kilogram) lander dropped from an orbiting mothership to make a three-point landing using a parachute and rocket engine.
