Answer 1

Answer:

The answers are:

The earth has an iron mantle.   False

The crust is made of tectonic plates False

The crust and the inner core are solid. False

The mantle surrounds the iron core. False

Oceanic plates lie under the beach. False

The Earth's crust includes both the ocean floor and dry land.  True

Explanation:

*The earth has an iron mantle.  

The mantle-- is composed mostly of silicate rocks rich in magnesium and iron.

*The crust is made of tectonic plates.

Crust-- crust is broken up into giant tectonics plates.

*The crust and the inner core are solid.

Compared to the rest of the layers, the crust is relatively thin and light.  The inner core is hotter on average than the outer core - it is solid because the center of the Earth is under higher pressures than outer layers.

The mantle surrounds the iron core.

Mantle--The layer of rock between the earth's crust and the outer core. Much thicker than the crust and contains most of the earth's mass. (67%)

Oceanic plates lie under the beach

Oceanic plates are formed by divergent plate boundaries. These zones, located along mid-ocean ridges

The Earth's crust includes both the ocean floor and dry land.

CRUST --layer of Earth that forms Earth's outer skin. It is a layer of solid rock that includes both dry land and the ocean floor.
