Which is a question which science cannot answer? How does the moon affect tides on earth? How long does it take for the earth to rotate on its axis? When will the next earthquake happen? Why do volcanoes erupt?

Till now we are able to find

a) How does the moon affect tides on earth? : the answer is moon gravitational field

b) How long does it take for the earth to rotate on its axis? : we know the answer is 24 hours (a day)

c) Why do volcanoes erupt? : due to divergence / convergence of tectonic plates

However we still cannot predict "When will the next earthquake happen?" based on science

Answer:Part 1.

Science cannot answer the presence of God.

Part 2. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon and away from the water on the far side. Since the earth is rotating while this is happening, two tides occur each day. Part 3.

23 hours and 56 minutes.

In this time all the stars appear to revolve once around the Earth and return to their starting positions. Pat 4. Next earthquake prediction can be made by earthquake prediction which is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, and particularly "the determination of parameters for the next strong earthquake to occur in a region. An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Part 5.

Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup).

It will rise to the surface or to a depth that is determined by the density of the lawa and the weight of the rocks above it.
