Answer:
Spring Tides.
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
The various types of ocean tides based on the position of the Earth, Moon and the Sun are;
I. Neap tides.
II. Spring tides.
III. Low tide.
IV. High tide.
V. Brown tide.
VI. Rip tide.
VII. Red tide.
Answer:
You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.
Have a great day! :D
