1. What layers of Earth make up the lithosphere?
the crust and the lower mantle
the crust and the upper mantle
the continental crust and the oceanic crust
the upper and lower mantle

2. Earth's thin, rocky outer layer is its _.
core
mantle
outer core
crust

3. Earth's core is made of an alloy of _.
iron and nickel
copper and iron
zinc and magnesium
iron and zinc1

Answer 1: The correct answer is the crust and the upper mantle.

The lithosphere refers to a solid, rocky part of the Earth, that is the Earth's outermost layer. It is comprised of the crust and upper mantle (refer to attached image). The lithosphere is around 100 km deep.

Answer 2: The correct answer is its crust.

The Earth's crust refers to the outermost rocky shell of the Earth where organisms live (refer to second image). The crust is made of solid rocks, including igneous, sedimentary and metamorphic rocks. The Earth's crust is around 30 km deep.

Answer 3: The correct answer is iron and nickel.

The Earth's core refers to the innermost or central part of the Earth. It lies around 2900 km beneath the Earth's surface and is spherical in shape. The Earth's core is comprised of an alloy (mixture) of the metals iron and zinc.It is made of two layers: the outer core and the inner core.

1. The layer of the earth that make up the lithosphere is the crust and the upper mantle.

2. Earth’s thin, rocky layer is called crust

3. Earth’s core is made of an alloy of iron and nickel

Further Explanation:

1. The lithosphere is the outermost layer and is brittle solid. The thickness of the layer is 100 Kilometers. It is composed of the crust and the upper mantle layer. The crust is divided into two different part based on chemical and physical properties namely, Oceanic crust and continental Crust.

2. The Earth’s crust is the outermost layer and is composed of igneous, sedimentary and metamorphic rocks. The crust is divided into two types namely, continental crust and oceanic crust. The thickness of the continental crust is between 30 kilometers to 50 kilometers while the thickness of the oceanic crust is between 5 kilometers to 10 kilometers.

3. The core is divided into two parts outer core and inner core. The thickness of the outer core is 750 miles is made of an alloy of nickel and iron. It also contain small quantities of dense metal like uranium, gold and platinum. These metal are found in molten state in the outer core. The inner core is made of iron.
