What are the differences and similarities between Venus and Earth?

Answer 1

Similarities between Earth and Venus are -

Similar in size

Very few craters indicating a relatively young surface

Density and chemical composition are similar

Differences between Earth and Venus are -

Venus has no moon

Venus' surface temperature is about 400 degrees Celsius

Venus' atmosphere is toxic to Earth based life

Venus' atmospheric pressure at the surface is about 90 times greater than Earths

Venus takes about 243 Earth days to complete one full turn on its own axis

Venus takes about 224 Earth days to complete one full orbit of the Sun

Scientists are considering the similarities and differences between Earth and Venus, to try to figure out Earth's fate.

Answer 2

Differences: Venus has a thick atmosphere mainly composed of carbon dioxide, causing a strong greenhouse effect and extremely high temperatures. Earth has a breathable atmosphere conducive to life. Similarities: Both planets have a similar size, mass, and composition. They also have volcanoes, mountains, and valleys on their surfaces.

Answer 3

There are many differences between Venus and Earth. Here are some of them:

1. Venus is the hottest planet in our Solar System and the surface averages at 462°C. The Earth, however, only averages at 14°C.
2. The surface of Earth is 71.11% water whilst Venus' surface is 0% water.
3. The Earth's diameter is 12,742km whilst Venus' diameter is slightly smaller at 12,100km.
4. The composition of Venus' atmosphere is mainly comprised of carbon dioxide (96.5%) whilst the Earth's atmosphere is mainly comprised of Nitrogen (78%) and Oxygen (21%). This makes Earth more habitable for life.
5. Wind on Venus can blow up to 60 times the speed of its rotation whilst Earth's wind can only blow up to 20% the speed of its rotation.
6. A year on Earth is 365.25 Earth days whilst a year on Venus is 224.7 Earth days.
7. A day on Earth is 23 hours and 56 minutes whilst a day on Venus is 243 Earth days. This makes Venus' day longer than its year. Venus is the only planet in our Solar System to have this feature.
8. Earth spins in a pro grade direction whilst Venus spins in a retrograde direction.
9. Earth's axial is slightly tilted at 23.5° whilst Venus' axial is tilted by 177.36°.

Answer 4

The first difference is that Venus does not have a natural satellite like the Moon that Earth has. The second difference is that Venus does not have a carbon cycle that traps the carbon dioxide that makes up ninety-six percent of its dense atmosphere. The third difference is that Venus is covered in opaque clouds of sulfuric acid so its surface cannot be seen from space with the visible eye such as Earths surface can be seen. Three similarities Venus and Earth share are their bulk composition, gravity, and size.

Answer 5

venus and earth are similar because they both are the same size, mass, and density. earth and venus are different because of earths atmosphere. venus's atmosphereic pressure is about 90 times the pressure on earth.

Answer 6

Differences

1.Well the differences are that Venus has an atmosphere that is made of mostly Carbon Dioxide (Co2) and Earth has an atmosphere made mostly of Nitrogen and Oxygen.

2.There is a lack of plate tectonics on Venus.

3.Venus is the hottest planet in the Solar System and has a thick Carbon Dioxide atmosphere.

Similarities

1. Both planets have a core,mantle and crust.

2.They nearly have the same gravity, so if you weighed 100 kilograms on earth you would weigh 91, you would barely feel the difference.

3.They both nearly have the same diameter.

Answer 7

Earth is the 3rd planet and Venus is the 2nd planet

Answer 8

1. the venus has no oceans.
2. the Venus is covered by a layer of thick clouds.
3. and there are trapping heat in its atmosphere.

Answer 9

The differences between Venus and Earth are that Venus have oceans like earth. Venus is much hotter than earth. the similarities are that Venus and Earth both have volcanoes.

Answer 10

Well there is allot of things alike with Venus and earth (espanol Venus y La Terrie)They are named the twin brothers
