The diagram below shows four coastline locations on earth with respect to the moon and sun at a given time. earth is shown as a circle with a smaller circle labeled moon to the right of it and a larger semicircle labeled sun to the right of that. points w and y are marked at the top and bottom ends of the circle representing earth. points x and z are marked at the left and right sides of the circle representing earth. in this current position, which coastline(s) are experiencing the high spring tides? both w and y both x and z only w only x

Both X and Z.

Explanation:

Spring tides are high tides which occur when the Sun, the Earth and moon line up in one straight line. The effect of gravity is maximum in this position and hence, causes high tides.Thus, the coastlines X and Z experience high tides and W and Y coastlines experience low tides. The spring tides have highest high tides and lowest low tides unlike Neap tides.

Thus, in this current position, coastlines which are experiencing the high spring tides are X and Z.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
