Explain what maria and craters are and how they formed. best answer will be marked as brainlest plz help.
Katen [24]
Lunar maria (plural form of the Latin word mare, which means sea) are dark surfaces that can be found all over the moon (17% of the Moon is covered in them) that have been created as a result of volcanic eruptions. These areas are made up of basalt, and given that they seemed almost waterlike, the astronomers in the distant past mistook them for seas, whence their name comes.
When it comes to craters, their origin is quite similar - volcanic eruptions created them. When lava starts erupting from a volcano, it has to get out from somewhere - and thus craters are created. If you are referring to lunar craters, however, there are many speculations as to how they were created: due to volcanic eruptions, meteoric impact, or glacier activity.

Brian hamilton has , which is an inflammation of the tissues surrounding his elbow. this was caused by a sports injury.
KIM [24]
This is called bursitis specifically olecranon bursitis. Olecranon bursa in the elbow is a thin fluid filled sac at the tip of the elbow. The bursa fills with fluid which can lead into inflammation on the surrounding area of the elbow resulting in pain and limitations of movement. Complications can happen if medical attention is not given. This includes bleeding, bruising, infectins, necrotizing fasciitis can also happen. Patient must undergo work up such as plain x rays, bone scintigraphy or if needed MRI/CT scan. Surgical interventions are usually needed because non surgical means are usually non effective. Long term monitoring is a must and patient must be advised on prevention practices.
