Which planet has the largest day/night temperature difference Weegy?
Which planet has the largest day-night temperature difference? A. Uranus B. Mercury C. Earth D. Venus. Mercury has the largest day-night temperature difference.
Why does Mercury have the largest temperature difference?
What Planet Has the Largest Temperature Difference? The conditions on every planet in the solar system are either much colder or much hotter than on Earth. There is such a large temperature difference on Mercury because it lacks an atmosphere.
Which planet has the greatest daily temperature change?
Which planet has the widest swings in temperature?
- Mercury experiences some of the most bizarre conditions.
- Venus has a very small axial tilt — 3 degrees versus Earth’s 23.5 degrees.
Which planet has highest temperature?
Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesn’t have any atmosphere, and atmosphere can hold and trap heat.
Which planet has the largest volcano?
Why is Mercury not hotter than Venus?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
What is Mercury’s temperature at night?
Since Mercury is the closest planet to the Sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury’s temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day. (This is hot enough to melt lead!)
Is Mercury hotter than Earth?
Mercury is hot. If we’re being quantitative, it’s actually extremely hot! As the closest planet to the Sun, it completes an orbit in just 88 Earth-days, achieving a maximum temperature during the day of a whopping 700 Kelvin (427 °C / 800 °F) at its hottest, equatorial locations.
How cold is Mars?
In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
Why is Mars the hottest planet?
Mars also has a hard time holding onto the heat it does get. On Earth, much of the sun’s heat gets trapped in our atmosphere, which acts like a blanket to keep our planet warm. But Mars’ atmosphere is about 100 times thinner than Earth’s — so heat from the sun can easily escape.
What planet has the most extreme temperatures?
Without an atmosphere, Mercury loses a great deal of heat into space, rather than sharing with its night side. The hottest planet, incidentally, is Venus, the second body from the sun. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C).
Which planet is red?
Why is Venus sometimes called Earth’s twin?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
How hot is Jupiter day and night?
Jupiter’s orbit around the sun is elliptical, or oval-shaped. Jupiter takes 12 Earth years to make one revolution around the sun, so one year on Jupiter is equal to 12 years on Earth. The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit).
Is Earth hotter than Mars?
Although Mars is smaller than the Earth, at 11% of Earth’s mass, and 50% farther from the Sun than the Earth, its climate has important similarities, such as the presence of polar ice caps, seasonal changes and observable weather patterns. It has attracted sustained study from planetologists and climatologists.
Is the sun a planet?
The Sun is the Solar System’s star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium, making it a main-sequence star.
How is Mars?
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
Why are volcanoes bigger on Mars than Earth?
Because the lower gravity of Mars generates less buoyancy forces on magma rising through the crust, the magma chambers that feed volcanoes on Mars are thought to be deeper and much larger than those on Earth. If a magma body on Mars is to reach close enough to the surface to erupt before solidifying, it must be big.
Which planet has the great red spot?
What caused the Tharsis bulge?
Tharsis is commonly called a volcano-tectonic province, meaning that it is the product of volcanism and associated tectonic processes that have caused extensive crustal deformation. According to the standard view, Tharsis overlies a hot spot, similar to the one thought to underlie the island of Hawaii.
Is Mercury a planet?
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 87.97 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.
How big is the sun on Mercury?
The Sun from Mercury. On average, the visible diameter of the Sun on Mercury is 2.5 times as large as it appears from Earth, and its total brightness is more than 6 times as great.
