What could have caused the formation of the sun?
What could have caused the formation of the sun?
Formation. The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. As the nebula collapsed because of its overwhelming gravity, it spun faster and flattened into a disk. Like all stars, the Sun will someday run out of energy.
How was the Sun formed step by step?
Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.
What is the theory that could best explain the formation of the solar system?
The most widely accepted theory of planetary formation is known as the nebular hypothesis. This theory mentioned that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
Which is the first step in building a solar system?
Answer:An explosion disturbs the gas and dust in the nebula. Explanation: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.
What is gravity in the solar system?
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
How many steps are there in the formation of a solar system?
6 steps
What is the name of our solar system?
Sol System
What is Earth’s core made up?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
Can you stand at the North Pole?
Unlike Antarctica, there’s no land at the North Pole. Instead it’s all ice that’s floating on top of the Arctic Ocean. Arctic sea ice usually reaches its minimum around mid-September each year.
