What are 4 Interesting facts about the earth’s crust?

Crust.

The crust is the thinnest layer of the Earth.

It has an average thickness of about 18 miles (30km) below land, and around 6 miles (10km) below the oceans.

The crust is the layer that makes up the Earth’s surface and it lies on top of a harder layer, called the mantle..

Earth’s oldest known piece of continental crust dates to the era of the moon’s formation. Australia holds the oldest continental crust on Earth, researchers have confirmed, hills some 4.4 billion years old.

What is Earth’s inner core called?

At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy. The outer core is about 1,355 miles (2,180 km) thick.

Why is the crust so important?

The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It’s also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.

What is Earth’s core made?

The outer core is about 1,400 miles thick, and it’s made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form.

How hot is the crust?

Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).
