To calculate the kinetic energy of moving tectonic plates, you would need to know the mass of each plate and their velocity. The formula for kinetic energy (KE) is:
\[
KE = \frac{1}{2} mv^2
\]
where:
- \( KE \) is the kinetic energy,
- \( m \) is the mass,
- \( v \) is the velocity.
Let's assume:
- The average mass of a tectonic plate is roughly 10^20 kg (this can vary significantly based on the size and type of plate).
- An average velocity of tectonic plates is about 2 to 5 cm/year (which is approximately 0.000056 to 0.00014 m/s).
To find the total kinetic energy of 7 tectonic plates, you would multiply the kinetic energy of a single plate by 7.
For example, using an average mass of \( m = 10^{20} \) kg and a velocity of \( v = 0.0001 \) m/s (just for calculation convenience), we can calculate the kinetic energy for one plate:
\[
KE = \frac{1}{2} (10^{20} \text{ kg})(0.0001 \text{ m/s})^2
\]
\[
= \frac{1}{2} (10^{20})(10^{-8}) = \frac{1}{2} (10^{12}) = 5 \times 10^{11} \text{ J}
\]
Now, for 7 plates:
\[
KE_{\text{total}} = 7 \times 5 \times 10^{11} \text{ J} = 3.5 \times 10^{12} \text{ J}
\]
This is an illustrative example to show how the calculation works with assumed values. The actual values of mass and velocity might significantly vary based on the specific tectonic plates being considered.
