Select the statement(s) that accurately describe the structure of Earth.
The outer core is nearly as hot as the sun’s surface.
We live on Earth’s crust.
The outer layer of Earth is made of mostly solid rock.
The inner core is made of liquid iron and nickel.
The mantle is below the crust and moves like thick oatmeal.
Let’s analyze each statement:
1. The outer core is nearly as hot as the sun’s surface. – This statement is somewhat misleading. The outer core is extremely hot, but not quite as hot as the sun’s surface, which is around 5,500 degrees Celsius. The outer core’s temperature is estimated to be between 4,500 and 5,500 degrees Celsius.
2. We live on Earth’s crust. – This statement is correct. Humans inhabit the Earth’s crust, which is the outermost layer of the Earth.
3. The outer layer of Earth is made of mostly solid rock. – This statement is partially correct. The outer layer (the crust) is primarily solid rock, although it also includes soil and sediments.
4. The inner core is made of liquid iron and nickel. – This statement is incorrect. The inner core is solid and composed mostly of iron and some nickel.
5. The mantle is below the crust and moves like thick oatmeal. – This statement is generally accurate. The mantle is semi-fluid and can flow slowly, similar to the consistency of thick oatmeal.
In summary, the correct statements are:
– We live on Earth’s crust.
– The mantle is below the crust and moves like thick oatmeal.
