Ultraviolet light split the water molecules, and the hydrogen then escaped to space. … That it has lost a tremendous amount of water as a result of molecules being split by ultraviolet light and the hydrogen escaping to space.

Which of the following is thought to explain why Venus has so much more atmospheric gas than Earth quizlet?

Venus has gained much more gas through outgassing than has Earth. Earth has lost much more gas to thermal escape than has Venus. Because of its lack of magnetic field, Venus has been able to gain gas through the impacts of solar wind particles, while Earth has not gained gas in this way.

What happened to the water on Venus quizlet?

What happened to the water that was believed to be on Venus? no ozone layer to protect atmosphere from radiation thus atmospheric water was broken up and much of the hydrogen was lost to space. As the surface of Venus warms, any oceans that did exist evaporates, and thus Venus cant rid its atmosphere of CO2.

Which one gives the primary reason why the surface of Venus today is some 450ºc hotter than the surface of Earth?

Which one gives the primary reason why the surface of Venus today is some 450ºC hotter than the surface of Earth? Venus has a much stronger greenhouse effect than Earth.

Why does Venus have such a great difference in temperature between its no atmosphere?

Which of the following is the main reason why Venus has so little wind erosion?

Which of the following is the underlying reason why Venus has so little wind erosion? –Without rotation, it lacks significant wind and therefore lacks wind erosion.

Why don’t we expect to find on planets orbiting high mass stars?

Why don’t we expect to find life on planets orbiting high-mass stars? … The high-mass stars emit too much ultraviolet radiation. The lifetime of a high-mass star is too short. -High-mass stars live only a few million years, and life probably cannot arise until a planet is at least a couple hundred million years old.

What happened to the water on Venus?

According to research presented by Moa Persson of the Swedish Institute of Space Physics (IRF), Venus actually retained most of its water over the past 4 billion years. Contrary to what researchers previously thought, Venus lost only a small amount of its water to a runaway Greenhouse Effect.

What is the status of liquid water on Venus today?

Venus’ surface is extremely dry. During its evolution, ultraviolet rays from the sun evaporated water quickly, keeping the planet in a prolonged molten state. There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause water to immediately boil away.

Why is Venus so hot quizlet?

Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus.

Which of the following best explains what scientists think happened to Outgassed water vapor on Venus quizlet?

Which of the following best explain what we think happened to outgassed water vapor on Venus? Ultraviolet light split the water molecules, and the hydrogen then escaped to space. … That it has lost a tremendous amount of water as a result of molecules being split by ultraviolet light and the hydrogen escaping to space.

What is Venus surface?

The surface of Venus is a very hot and dry place. Most of the surface is made up of gently rolling plains. Venus has several large lowlands and two large highland areas which are about the size of Australia and South America.

What is the most likely reason Venus does not experience plate tectonics like Earth?

What is the most likely reason Venus does not experience plate tectonics like Earth? Venus’s lithosphere is stronger and thicker than Earth’s. How have we been able to construct detailed maps of surface features on Venus? rising material in the mantle of Mars.

What is the primary cause for the differences in climate between Mars and Venus quizlet?

the interaction of particles from the Sun and Earth’s atmosphere and magnetic field. … winds lift dust into the atmosphere. The differences in the climates of Venus, Earth, and Mars are caused primarily by. the thickness of their atmospheres.

What is the primary cause for the difference in climate between Mars and Venus?

Despite these similar initial conditions, Venus is now too hot for life and Mars is too cold. This difference in temperatures is caused partially by the different values for energy incident on these planets. The main difference is still caused by the composition and thickness of a planets atmosphere.

Which of the following worlds has the greatest difference in temperature between its no atmosphere temperature and its measured temperature?

12) How does the greenhouse effect work? A) Greenhouse gases transmit visible light, allowing it to heat the surface, but then absorb infrared light from Earth, trapping the heat near the surface. B) The higher pressure of the thick atmosphere at lower altitudes traps heat in more effectively.

Which of the following most likely explains why Venus?

Ch7 concept quiz

Question
Answer
Which of the following most likely explains why Venus does not have a global magnetic field like Earth? its rotation is too slow
What are the two geological features that appear to set Earth apart from all the other terrestrial worlds? plate tectonics and widespread erosion

Which of the following would be a reason why Venus does not have a magnetic field?

Which of the following would be a reason why Venus does not have a magnetic field? Venus’s very slow rotation rate does not allow a magnetic field to form.

Why do you expect to find only large impact craters on the surface of Venus?

Compared to Mercury, the Moon and other such bodies, Venus has very few craters. In part, this is because Venus’s dense atmosphere burns up smaller meteorites before they hit the surface. … The impact crater distribution appears to be most consistent with models that call for a near-complete resurfacing of the planet.

Would you expect to find similar life forms on a planet orbiting a star with 10 times the Sun’s mass?

The lifetime of a star is roughly inversely proportional to its mass cubed. … So a star ten times more massive than our sun would live for just 1/1000th as long. We expect our sun to have a life in excess of 10 billion years, so a superstar with ten times our sun’s mass would live just 10 million years.

Why didn’t oxygen begin to accumulate in the atmosphere until approximately 1.5 billion years after life appeared on Earth?

3) Oxygen did not build up in the atmosphere as soon as life began to produce it because the oxygen was pulled back out of the atmosphere by reactions with surface rocks.

When did oxygen start accumulating in the atmosphere?

2.33 billion years ago

Caption: MIT scientists say that the Great Oxygenation Event (GOE), a period that scientists believe marked the beginning of oxygen’s permanent presence in the atmosphere, started as early as 2.33 billion years ago.

Does Venus have water vapor?

Venus today is a hellish world. It has a crushing carbon dioxide atmosphere 90 times as thick as Earth’s. There is almost no water vapor. Temperatures reach 864 degrees Fahrenheit (462 degrees Celsius) at its surface.

When did Venus last have water?

Recent studies from September 2019 concluded that Venus may have had surface water and a habitable condition for around 3 billion years and may have been in this condition until 700 to 750 million years ago.

What forms of water are found on Venus?

Well, there isn’t any water on the surface of Venus, in form of rivers, lakes or oceans. The average temperature on Venus is 461.85 °C. Since water boils at 100 °C, it couldn’t be on the surface.

How would you survive on Venus?

Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry planet with no evidence of water, its surface temperature is hot enough to melt lead, and its atmosphere is so thick that the air pressure on its surface is over 90 times that on Earth.

Do you think life can exist on Venus planet Class 10?

No life does not possible on venus as due to atmosphere that contains H2SO4(Sulphuric acid) that acts as a dehydrating agent and hydrate water molecules so there is no H20 (Water) and Oxygen as the environment of earth.

Does Venus have oxygen yes or no?

Without life there is no oxygen; Venus is a bit closer to the Sun so it is a bit warmer so there is slightly more water in the atmosphere than in Earth’s atmosphere. without oxygen there is no ozone layer; without an ozone layer, there is no protection for the water from solar ultraviolet (UV) radiation.

How long is a year on Mars?

687 days

Why is Venus much hotter than Earth?

Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. … This trapping of heat by the atmosphere is called the greenhouse effect because it is similar to how the glass in a greenhouse traps heat.

Why is Mars red?

Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.

What is the leading hypothesis for Venus’s lack of water?

What is the leading hypothesis for Venus’s lack of water? Its water molecules were broken apart, and hydrogen was lost to space. What causes the release of oxygen into Earth’s atmosphere?

Which of the following explains why might Venus has a weaker Coriolis effect than Earth?

Why is the Coriolis effect so weak on Venus? Because Venus rotates so slowly. All of the following have occurred over long periods of time on Earth. … Most of the gases that have been released from volcanoes on Earth later returned to the surface.
