Picture the Earth like a giant peach floating in space. On its surface is a thin skin called the crust. Instead of fleshy fruit,
just below that is the rocky mantle. Deep in the center, like the peach's pit, sits the Earth's core. The inner core is solid, extremely hot and under immense pressure from all the rock above it. The outer core is molten, so it's liquid, and also very hot. This core extends 1,800 miles around from the center of the Earth.
The layer after the core is the mesosphere. This layer is mostly solid and extends outward another 1,500 miles. The asthenosphere is a thin layer, about 150 miles thick, at the border between the mantle and the crust. It is still very hot, and nearly (but not quite) a liquid. Because of this, pieces of the Earth's crust can move very slowly above it.
Which of the following is true about the Earth’s layers?
A: The asthenosphere is the thickest of Earth’s layers.
B: All of the layers are liquid and extremely hot.
C: There is little to no pressure on the solid core.
Planting vegetation can reduce noise because plants are known for absorbing noise. The noise would be reduced so the person living in the home would rarely notice. Someone driving on the highway would still hear the noise but it would be faint.The doppler effect is frequency so putting plants there will lower the frequency.
