Week 7 Assignment 103
1. What is Earth’s mantle? The mantle is a part of a terrestrial planet or other rocky body large enough to have differentiation by density. The interior of the Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a layer between the crust and the outer core. ...
2. What elements make up the Earth’s mantle? Magnesium, silicon, iron and oxygen, aluminum, silicon, calcium, sodium and potassium
3. Describe the “big splash” theory of the Moon’s origin? The Big Splash Theory is the current theory that explains the formation of the Moon. This theory states that approximately 4.5 billion years ago, the Moon was formed as a result of an object approximately the size of Mars colliding with Earth, causing less dense portions to be blasted into space. The clash created high temperatures and pressures, which in turn caused denser materials (like Iron) to become part of the Earth’s core. The less dense materials were blasted into space adding to the material orbiting the Earth. These less dense portions gravitated toward each other, creating the Moon. Evidence supporting the Big Splash Theory came from rock and soil samples taken during the Apollo landings on the Moon.
4. How are comets different from asteroids? One of the main differences between comets and asteroids are what they are made of. Asteroids are made up of metals and rocky materials while comets are made up of ice, dust and rocky material. Asteroids formed near the sun while comets farther away. Comets have tails while asteroids don’t. Also another difference is their orbit patterns.
5. Of what are comets made? Ice, dust and rocky material. And asteroids? Metals and rocky materials
6. If you grew up on the moon, would your bones be heavier or lighter than they are now Lighter because the moon has almost the same density but much smaller size and as result interaction between any mass on the moon surface is weaker than on earth surface. Lighter because the moon has
