Explanation:
Answer is D: the current make up of the crust
Changes in the temperature of the Earth's core will do the following:
1. Cause the outer core to solidify
-this means that the liquid outer core which is responsible for generating the magnetic field protecting us humans from solar radiation will be gone
2. Cause the mantle to solidify
-this means that if the mantle solidifies, the plate tectonics will stop moving around, and if this happens, the earthquakes and volcanoes will not be produced anymore and also mountain ranges will not be renewed, and the earth will be flattened by erosion.
an agent, such as radiation or a chemical substance, which causes genetic mutation.
Answer:
80 dB
Explanation:
Sound intensity is inversely proportional to the square of the distance traveled by the sound.
Thus;
r1^2 divide by r2^2 = L2divideL1
where r= distance (m)
L= sound intensity (decibal dB)
8squared divide by 4 squared = L2 divide 20 dB
L2 = 4 × 20
L2= 80 dB
This means that the sound is increased from 20 dB to 80 dB.
