Question

which conclusion is supported by information in the table?
the mantle is thinner than the crust.
the core is the thickest of earth’s layers.
the inner core is thicker than the outer core.
the mantle is the thinnest of earth’s layers.
table with columns: crust, upper mantle, lower mantle, outer core, inner core; rows: thickness (km), density (g/cm³) top and bottom, types of rock found

Explanation:

Step1: Analyze each option

• Option 1: The mantle (upper mantle 720 km + lower mantle 2171 km = 2891 km) is thicker than the crust (30 km), so this is false.
• Option 2: Calculate total core thickness: outer core (2259 km) + inner core (1221 km) = 3480 km. Mantle thickness: 720 + 2171 = 2891 km. Crust: 30 km. So core (3480 km) is thicker than mantle and crust, so it's the thickest. This is true.
• Option 3: Inner core (1221 km) is thinner than outer core (2259 km), so this is false.
• Option 4: Mantle (2891 km) is not the thinnest; crust (30 km) is thinner, so this is false.

Answer:

The core is the thickest of Earth’s layers.
