Between the outer core and crust is the mantle, an incredibly hot layer of molten rock about 1,800 mi (2,900 km) thick with the consistency of caramel. And lastly, the outermost layer of Earth is Earth's crust, a layer that averages about 19 miles (30 kilometers) deep on land.

Earth’s structure is stratified, with a solid inner core about 759 mi (1,221 km) in radius, composed mainly of iron and nickel, and reaching temperatures up to 9,800°F (5,400°C). Enveloping the inner core is the outer core, a layer about 1,400 mi (2,300 km) thick, made of iron and nickel fluids.

The creation and development of what we know as Earth are believed to have begun around 4.5 billion years ago, as swirling gas and dust were drawn together by gravity and gradually accumulated through a process known as accretion.

Colorful, stunning. And maybe toxic and poisonous… This is the Poison Dart Frog. They can range in many bright colors — yellow, blue, orange, and so on. Though, despite their beauty, they can be deadly. The Golden Poison Dart Frog, for example, possesses enough poison to kill 20,000 mice.
