Detailed explanation-1: -Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
Detailed explanation-2: -Most meteoroids are made of silicon and oxygen (minerals called silicates) and heavier metals like nickel and iron. Iron and nickel-iron meteoroids are massive and dense, while stony meteoroids are lighter and more fragile.
Detailed explanation-3: -Explanation: Statement 1 is correct: Meteoroid is a much smaller rock or rock particle from a comet or asteroid orbiting the Sun. Statement 2 is correct: Meteor-If a meteoroid enters the Earth’s atmosphere and vaporizes, it becomes a meteor, which is often called a shooting star.
Detailed explanation-4: -Comets are made from rock, dust, and ice. These objects are mostly frozen until they orbit close to the sun and warm up, releasing gases. A meteor, however, is made of rock and metal.
