Explanation / Answer
Earth mantle is layer that is Bremen the crust and the outer core..
Earth mantle is made of 44.8% of oxygen, 21.5% silicon, 22.8% magnesium along with iron, calcium and sodium.
According to the Big Splash moon I'd formed out of waste or debris about 4.5 billion years ago because of Collison between earth and an astronomical body.
Asteroids are made up of metals and the rocky substance while comets are made up of dust, rock substance and ice.
In moon the bones will be lighter.
The world's longest and tallest mountain chain on Earth is Andes. It formed by the process of plate tectonics.
Plate tectonics move because of enormous heat in earth's core that causes the molten rock in the mantle Layer to move
it moves in a pattern which is knows as convection cell.
The Earth's outer layer the crust is divided into the set of moving plate and the lines where they meet is knows aa plate boundaries while transform plate boundaries are situated where two plates side one another.
Geological activities along transform plate boundaries are earthquakes and volcanic activities.
