explain the layer of the earth.
Answers
Answer:
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. ... Continental crust is less dense, thicker, and mainly composed of granite.
Explanation:
To prevent the spread of COVID-19:
Clean your hands often. Use soap and water, or an alcohol-based hand rub.
Maintain a safe distance from anyone who is coughing or sneezing.
Wear a mask when physical distancing is not possible.
Don’t touch your eyes, nose or mouth.
Cover your nose and mouth with your bent elbow or a tissue when you cough or sneeze.
Stay home if you feel unwell.
If you have a fever, cough and difficulty breathing, seek medical attention.
Calling in advance allows your healthcare provider to quickly direct you to the right health facility. This protects you, and prevents the spread of viruses and other infections.
1.Crust-“Crust” describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. ... Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.
2.Mantle-The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
3.Outer core-Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.
Inner core-Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius. There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle.
