Answer:

A lunar eclipse can only occur when there is a full moon.

Explanation:

A lunar eclipse occurs when the Moon, Earth and Sun are aligned on a straight line. This alignment completely blocks the sunlight and moon is under the shadow of Earth. In this phase, moon often look red because of reflection of infrared radiations. This happens only where there is a full moon.

It is not possible to occur moon eclipse in any phase because if sunlight would reach the moon surface directly, it is not a moon eclipse Further, lunar eclipse can last upto a few hours because the shadow of Earth is greater because of its size compared to the moon's size and it takes a while until moon is completely out of that shadow. Lastly, a lunar eclipse doesn't create an eerie color in the sky rather a red color due to infrared radiations.

Which direction do a comet's dust and plasma tails point?
masya89 [10]
Dust and particulate trails point in the direction opposite of the star closest to it. The outgoing solar energy and radiation slowly shaves off matter of the object, and thus creates a tail behind the object. Simply put, the tail is on the dark side of the object.

Gelneren [198K]

Answer;

-Association

Regions of the cortex that are NOT primarily concerned with sensation or movement are termed the association cortex.

Explanation;

-Association cortex is the cerebral cortex outside the primary areas.  It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation, for which primary sensory areas appear to be necessary.

-The association cortices include most of the cerebral surface of the human brain and are largely responsible for the complex processing that goes on between the arrival of input in the primary sensory cortices and the generation of behavior.
