What is the world made up of
Answers
Answer:
The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.
Answer:
★ The Crust -
The crust is found beneath mountain ranges and can be as thick as 40 kilometres. However, the Earth’s crust under oceans is only about 8 kilometres thick.
★ The Mantle -
Parts of the Earth’s mantle are made up of hot rock, so they melted. This molten rock seeps through cracks in the crust and pours out of volcanoes. This is called lava. When the lava cools down, it turns into stone.
★ The Core -
Scientists believe that the Earth’s core is mostly made up of iron. They feel that the inner core is solid while the outer core is in a liquid state.
