Let’s evaluate the statements about Earth’s structure one by one:
1. The outer core is nearly as hot as the sun’s surface.
– False. The outer core’s temperature ranges from about 4,000 to 5,000 degrees Celsius, while the sun’s surface is around 5,500 degrees Celsius.
2. We live on Earth’s crust.
– True. The Earth’s crust is the outermost layer where we find land, oceans, and life.
3. The outer layer of Earth is made of mostly solid rock.
– True. The outer layer, or crust, is primarily composed of solid rock.
4. The inner core is made of liquid iron and nickel.
– False. The inner core is actually solid, composed mainly of iron and nickel, while the outer core is the liquid part.
5. The mantle is below the crust and moves like thick oatmeal.
– True. The mantle, which lies beneath the crust, behaves like a viscous fluid and can flow slowly, often compared to thick oatmeal.
### Summary:
The statements that accurately describe the structure of Earth are:
– We live on Earth’s crust.
– The outer layer of Earth is made of mostly solid rock.
– The mantle is below the crust and moves like thick oatmeal.
