Which planet has the largest volcano?
What is the biggest volcano in the galaxy?
Which planet has the most volcanoes in our solar system?
Do any other planets have volcanoes?
Active volcanoes in the Solar System. Mars, Venus and the Jupiter moon Europa might still have volcanic activity as well, but there have been no direct observations of eruptions as evidence so far.
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.
What is the most dangerous volcano in the world?
Italy’s Vesuvius has been a menacing figure since an eruption in 79 CE buried the city of Pompeii. Over the last 17,000 years, the volcano has gone through eight major explosive eruptions that were followed by large pyroclastic flows, according to the Smithsonian Institute/USGS Global Volcanic Program database.
What is the biggest volcano on Venus?
What is the greatest canyon in the solar system?
How tall is the tallest volcano in the world?
Does Venus have more volcanoes than Earth?
The surface of Venus is dominated by volcanic features and has more volcanoes than any other planet in the Solar System. It has a surface that is 90% basalt, and about 65% of the planet consists of a mosaic of volcanic lava plains, indicating that volcanism played a major role in shaping its surface.
What planets have people walked on?
- Earth’s Moon.
- Moons of Mars.
- Moons of Saturn.
Do all inner planets have volcanoes?
The Moon is similar, but lacks a substantial iron core. Three of the four solar terrestrial planets (Venus, Earth, and Mars) have substantial atmospheres; all have impact craters and tectonic surface features such as rift valleys and volcanoes.
What are volcanoes named after?
Etymology. The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology. The study of volcanoes is called volcanology, sometimes spelled vulcanology.
How were volcanoes discovered on Io?
The volcanology of Io, a moon of Jupiter, is the scientific study of lava flows, volcanic pits, and volcanism (volcanic activity) on the surface of Io. Its volcanic activity was discovered in 1979 by Voyager 1 imaging scientist Linda Morabito.
Do any moons have an atmosphere?
In addition to Earth, many of the other astronomical objects in the Solar System have atmospheres. These include all the gas giants, as well as Mars, Venus, and Pluto. Several moons and other bodies also have atmospheres, as do comets and the Sun. There is evidence that extrasolar planets can have an atmosphere.
Does Sun move around Earth?
Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), and one complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). Earth’s orbit has an eccentricity of 0.0167.
When did Mount Everest erupt?
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 Yellowstone National Park a volcano?
The Yellowstone Caldera is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States, sometimes referred to as the Yellowstone Supervolcano. The caldera and most of the park are located in the northwest corner of Wyoming.

What causes shield volcanoes to erupt?
This is caused by the highly fluid (low viscosity) lava erupted, which travels farther than lava erupted from a stratovolcano, and results in the steady accumulation of broad sheets of lava, building up the shield volcano’s distinctive form.
Does Venus have a tilted axis?
The axial tilts of Venus, Uranus and Pluto are greater than 90 degrees for the following reasons: Venus: Venus is rotating very slowly in a retrograde direction, opposite to the direction of planets like Earth.
How long is the largest canyon?
The Yarlung Tsangpo Grand Canyon (or Tsangpo Canyon), along the Yarlung Tsangpo River in Tibet, is regarded by some as the deepest canyon in the world at 5,500 m (18,000 ft). It is slightly longer than the Grand Canyon in the United States.
How many grand canyons are there?
The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
Why does Mars have ice caps?
In other words, the winter buildup of ice changes the gravity of the planet. Mars has seasons that are similar to Earth’s because its rotational axis has a tilt close to our own Earth’s (25.19° for Mars, 23.45° for Earth). The south polar cap is higher in altitude and colder than the one in the north.
What does the word pocho mean?
Pocho (feminine: pocha) is a term used by Mexicans (frequently pejoratively) to describe Chicanos and those who have left Mexico. The word derives from the Spanish word pocho, used to describe fruit that has become rotten or discolored.

Is Earth the only inner planet with a moon?
