Limestone, Sandstone, and Shale are all sedimentary rocks so granite is the answer.
The answer is when the sun and the moon are at the right angles to the earth
Which make the sun, the earth and the moon formed a 90 degree angle.
during neap tides, the gravitational forces between the 3 counteract one another, creating a weaker tidal forces
All vegetable life, and therefore animal life, is based on the approval of sunlight, as plants (the primary consumers) perform photosynthesis, which is the process by which solar energy is converted into chemical energy , in the form of sugars. In this way, animals that feed on plants absorb solar energy. The second way the Earth absorbs solar energy is through its seas and oceans, which tempers the warm water and creates the warm ocean currents that carry the heat all over the planet.
The finest sedimentary particles would be found at the mouth of the river. These particles have been eroded by debris and water. They are easily carried out to be deposited near the end of the river.
