Answer:

Explanation:
The frequency and the wavelength of a wave are related by the equation

where
v is the speed
f is the frequency
is the wavelength
For the sound wave in this problem, we have
f = 634 Hz (frequency)
(wavelength)
Therefore, the speed of the wave is

The speed of sound in air depends on the temperature according to the equation

where T is the temperature.
In this problem, we know the speed, so we can calculate the temperature:
Convection currents are caused by the movement of the magma in the mantle.

Good Luck Studying :)
In a chemical formula, the part to the left of the arrow represents the reactants. The reactants are all the chemical elements that will react with each others to make the products (which will be on the right part of the arrow).
Example:
H2 + O2 --> H2O
H2 and O2 are the reactants (on the left part of the arrow) and H2O is the product (on the right side of the arrow)
Hope this helps! :)
