A 4 column table with 5 rows. First column is unlabeled with entries: Crust, uppercase mantle, Lower mantle, Outer core, Inner core. Second column is labeled Thickness in kilometers with entries: 30, 720, 2,171, 2,259, 1,221. Third column is labeled Density in grams per centimeters cubed, divided into Top and Bottom columns. Top entries are: 2.2, 3.4, 4.4, 9.9, 12.8. Bottom entries are 2.9, 4.4, 5.6, 12.2, 13.1. Fourth column is labeled Types of Rock Found with entries: Silicic rocks, Peridotite, Magnesium and silicon oxides, Iron plus oxygen, Iron plus oxygen.
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.
1 answer
The conclusion supported by the information in the table is:
The core is the thickest of Earth’s layers.
This is evident from the thickness measurements provided; the outer core (2,259 km) and inner core (1,221 km) combined are thicker than both the crust (30 km) and mantle (720 km).
