The Layers of the Earth

Layers of the Earth

• The Earth consists of four main layers: the crust, mantle, outer core, and inner core.
• The crust is the outermost layer, composed of solid rock and mineral formations, varying in thickness from about 5 to 70 kilometers.
• Beneath the crust lies the mantle, which extends to a depth of approximately 2,900 kilometers and is made of semi-solid rock that can flow slowly over time.
• The outer core is a liquid layer composed mainly of iron and nickel, responsible for generating the Earth's magnetic field.
• The inner core is a solid ball of iron and nickel with temperatures reaching up to 5,700 degrees Celsius, believed to be as hot as the surface of the sun.

Animal Sounds

• Dogs often make a barking sound, typically used for communication or expressing alertness or excitement.
• Cats produce a meowing sound, primarily used to communicate with humans and other cats, conveying various emotions such as hunger or affection.
