I would say that in very fast moving water such as in a river, the cobble size could be transported because cobbles are 64-256mm so are quite big and in a quiescent stream won't move much but in a freshet say in a steep mountain stream they can be rolled along such as I observed in the local streams at a mining town during the Hurricane Fifi in Honduras in 1974.

<h2>Answer: They are extra-high tides and extra-low tides.</h2>

Explanation:

Tides are periodic movements of the great masses of water on our planet as part of the gravitational attraction exerted by the moon and the sun on Earth.

In this sense, there are two very special cases: The Spring and Neap tides.

<u>Spring tides </u>

Occur when there is a full moon or new moon, which makes the <u>tides higher.</u> During these lunar phases, the Moon, the Earth and the Sun are aligned and the gravitational attraction power is greater.

<u>Neap tides </u>

Occur when the moon, the earth and the sun form a right angle ( $90\º$ ), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.
