VENUS By Alex Theodore

What Are The Differences Between Venus and Earth?

Venus and Earth are very similar because of their size and mass. Venus is also known as Earth's sister. Like Earth, Venus used to have water as well but because of it's extreme heat the water evaporated many billion years ago. Venus has a similar core to Earth which is made out of solid metal but Venus doesn't have a planet sized gravity field. Because of Venus' greenhouse affect the planet is a gateway to hell with temperatures souring up to 470* C, also with nights going down -173*C. Venus' clouds are made out of pure sulphuric acid. The clouds on Venus are approximately 50-70 km high in the sky. The weather on Venus compared to Earth's is very extreme with clouds snowing metal from the sky and raining acid. Due to the amount of clouds Venus is reflective and there is no visible part of it. A full rotation around the sun takes Venus 243 Earth says when Earth takes 355.2 days. Unlike Earth that rotates anti-clockwise, Venus rotates clockwise and is the only planet in the solar system that does.

How Was Venus Created/Formed?

Like all other planets in our solar system, Venus was formed roughly four billion years ago. When Venus first started it was just a metal core floating around in space. The way that Venus progressed is that other lighter elements started to connect to that metal core to create a bigger object. The way that the elements joined to the core is that the gravity force pulled it together. In the first stages of Venus' forming it was just a big cloud of carbon dioxide and other gasses. The way that Venus became so uninhabitable is because of the green house affect caused on the planet. If there wasn't so much acidic coverage over the planet maybe it could be inhabited. Because of the heat of Venus, there is no more planet gravitational pull.

Is Venus' core and layers like Earth's?

Like Earth, Venus has a core, mantle and crust. The core of Venus is made out of solid metal like Earth's but doesn't have a gravitational pull anymore covering all of Venus. Roughly a couple billion years ago it still did. Some scientists are still not sure whether the core of Venus is solid or a liquid because of its features. Some evidence that supports that the core is liquid is that the planet doesn't have a planet gravitational pull. Roughly about 300-500 million the tectonic plates on the planet shut down. The upper crust of the planet Venus is rocky and hellish. The volcanoes on Venus are still active after 4 billion years. The volcanoes on Venus are really large, some of them have a diameter of over 20 km. On Venus 85% of it is covered by volcanoes.

How does the weather on Venus change so quickly?

Venus being the second planet closest to the Sun is the hottest in our solar system. The weather on Venus is always changing and scientists are still figuring out why. One of the reasons that the weather Venus is so unbalanced is because the pressure on the planet is 93 times higher than Earth's. Venus is covered by sulphuric acid clouds that traps all of the heat coming from the Sun. If everyone on Earth continues the way that we are going Earth will become like Venus with the greenhouse affect effecting the whole planet. The winds on Venus are so fast going over 360 kph which is faster than most Supercars. A while ago Venus used to receive even more sunlight from the Sun(40% more than Earth). CO2 plays a main catalyst in keeping Venus so hot and cold.

What is Venus' climate and average forecasting?

As it is stated in the last paragraph the weather on Venus can change so swiftly. It is nearly impossible to get a proper forecasting of Venus because one day on Venus is 117 Earth days. The climate on Venus is no where near liveable and the atmosphere being made out of 96% carbon dioxide doesn't help to support life on the planet. Venus is constantly being crushed with wild weather. Not only winds on Venus going over 360 kph but there are winds around it over 1 million kph.
