Why the moon is shown with different forms?
Great inspiring poets and romantics the moon was a mystery and source of legends.
"Companion of the planet forever?
There are several theories about this, some associated with the moon and the earth a common origin, others explain that it was actually drawn at some point on the earth or that it is an evolution of the planet and the most accepted to date is formed after an enormous impact on the earth by another celestial body.
is classified as a natural satellite that is orbiting the planet in the translation came around the central star (sun). It is one of the larger satellites of the solar system and even see it shine, do not have their own light, only see the reflection of light from the sun and as the rotation (spin on its axis) is in sync with your translation always see the same face. This appeared to be casual and repeated in several of the satellites of our solar system.
We will all see the different ways in which the moon appears in the sky. These shapes are called phases and depend on the position that the moon relative to the sun and the earth.
As the earth revolves around the sun and the moon makes around the earth, the positions adopted against sunlight may be as follows
T (ground) ---- L (moon) --- - S (sol) from the land where we see the dark side and the bright faces the sun, this is the so-called invisible new moon phase. That it is invisible to our eyes.
When away from that position with clockwise rotation is placed
T ------ S began to see the new moon rising in our
L
southern hemisphere appears as a wide small letter C fine, that letter is slowly growing into position
T ------- S L where she became a semicircle or crescent when it is 90 degrees with respect to the line joining the sun to the earth continues to rotate until
L ------ T ------- S the full moon or full moon where we see his face fully illuminated.
In its clockwise rotation to acquire the following position:
T ------- S L
begins to appear as a letter D with decreasing phase that is illuminated in the last quarter showing as a semi-circle D-shape when positioned at 90 degrees but the opposite side of the waning crescent and continues to re-position the new moon invisible.
This tour lasts approximately 28 days so that in one year tends to make 13 trips moles. In the northern hemisphere as C is waning while the D is growing. This small satellite
physical laws exert attractive forces on earth like the sun, so that fluids (sea and air) will be brought to her causing the tides and variations in atmospheric pressure between 990 Hp ( hecto pascals) and 1040 Hp be the normal pressure of 1013 Hp. When the tide is low pressure and vice versa.
A Hp causes a change in barometric tide 1cm. Generating high tide or high tide or low tide.
In our country, the Naval Hydrographic Service belonging to the Ministry of Planning of the Ministry of Defence, published daily predictions with the times and heights of high and low waters of the ports of Argentina and the daily predictions of tidal currents. The calculations are performed by the Computer Center of the department of oceanography.
Wondering why? we go a little along the path of scientific knowledge.
