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.
Why is the Coriolis effect so weak on Venus?
Why is the Coriolis effect so weak on Venus? Because Venus rotates so slowly.
Which of the following is thought to explain why Venus has so much?
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 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 happened to water on Venus?
At Venus, the solar wind strikes the upper atmosphere and carries off particles into space. Planetary scientists think that the planet has lost part of its water in this way over the four and a half thousand million years since the planet's birth.
Where is the water that Venus may have started with quizlet?
Venus may have started with an ocean's worth of water. Where is its water now? The water was lost when ultraviolet light broke apart water molecules and the hydrogen escaped to space.
Which of the following most likely explains why Venus does not have a strong magnetic field quizlet?
Which of the following most likely explains why Venus does not have a strong magnetic field? Its rotation is too slow.
Does Venus have a Coriolis Effect?
Because the planet rotates very slowly the Coriolis Effect on Venus is extremely weak. Rotating on its axis about once every 24 hours the Coriolis Effect on the motion of the Earth's atmosphere is quite strong, creating continent sized swirls of cloud systems which are easily visible from space.
Is there water vapor on Venus?
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.
Which of the following is the underlying 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.
What would the Venus no greenhouse temperature?
Planets with low albedo absorb more sunlight, leading to hotter temperatures. Venus would be 510°C colder without greenhouse effect.
Was there water in Venus?
Past habitability potential 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.
Why did Earth retain most of its water while Mars and Venus did not quizlet?
Why did Earth retain most of its water while Venus and Mars lost theirs? The basic answer is that Earth was at just the right distance to retain water as liquid. Venus lost its water because it was too hot.
Which of the following best describes rain on Venus?
Which of the following best describes rain on Venus? It has sulfuric acid rain in its atmosphere, but the drops evaporate before hitting the surface.
Which of the following most likely explains why Venus does not have a strong magnetic field group of answer choices?
Which of the following most likely explains why Venus does not have a global magnetic field like Earth? Its rotation is too slow.
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.
How did Venus lose water?
At Venus, the solar wind strikes the upper atmosphere and carries off particles into space. Planetary scientists think that the planet has lost part of its water in this way over the four and a half thousand million years since the planet's birth.
Is Venus gravitationally locked?
Venus is kept in orbit due to the gravitational pull of the Sun. However, this is distinct from tidal locking, which requires that the locked object rotate both around its axis and the body to which it is locked to at the same rate.
What happened to the planet Venus?
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.
Which of the following statement can explain the reason that Earth’s continental crust has lower density than Seafloor crust?
Why is continental crust lower in density than seafloor crust? Continental crust is made from remelted seafloor crust and therefore only the lower-density material rises to form it. How fast do plates move on Earth? one plate slides under another, returning older crust to the mantle.
Which of the following most likely explains why Venus does not have a global magnetic field?
Which of the following most likely explains why Venus does not have a global magnetic field like Earth? Its rotation is too slow.
What is the greenhouse effect on Venus?
For a really strong greenhouse effect, we should look at Venus. Venus is similar to Earth in terms of size and mass, but its surface temperature is about 460 degrees Celsius. This is hot enough to melt lead! The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas.
Why does Venus have greenhouse effect?
As a result, the planet's early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, carbon dioxide built up in the atmosphere, leading to a so-called runaway greenhouse effect that created present conditions.
What happened Venus water?
At Venus, the solar wind strikes the upper atmosphere and carries off particles into space. Planetary scientists think that the planet has lost part of its water in this way over the four and a half thousand million years since the planet's birth.
Why did Earth retain most of its Outgassed water?
EArth retained its outgassed water because temperatures were low enough for water vapor to condense into rain and form oceans.
Why isn’t liquid water stable on Mars today and why do we nonetheless think it flowed on Mars in the distant past?
Explain why liquid water is not stable on mars today, but why we nonetheless think it flowed there in the distant past. – a.) Because Mars is so cold, so water would immediately freeze into ice; air pressure is so low that liquid water would quickly evaporate.
What does it rain on Venus?
The acid rain on Venus is caused by the reaction of sulphur dioxide and water in the planet's atmosphere. Despite being many times more corrosive than the most acidic rain on Earth, Venusian rainstorms are not a significant contributor to surface erosion.
What happened Venus atmosphere?
It is speculated that the atmosphere of Venus up to around 4 billion years ago was more like that of the Earth with liquid water on the surface. A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases.
Which of the following could explain why Mars today lacks a global magnetic field like that of Earth?
Terms in this set (20) Recent evidence suggests that Mars once had a global magnetic field. Assuming this is true, which of the following could explain why Mars today lacks a global magnetic field like that of Earth? Mars's interior has cooled so much its molten core layer no longer undergoes convection.
How will you explain the fact that Venus has no magnetic field despite its molten metallic core?
Venus also probably has a molten core, but because it spins very slowly (once every 243 Earth days) it does not generate a magnetic field. Mercury, Mars, and the Moon have solid cores, so they also do not have much of a magnetic field.
