Umbra!

during the lunar eclipse or also known are the red moon, the moon is fully engulfed in the earths shadow, or umbra. this is because the moon is BEHIND the earth. another way to remember is this little path called the red path or lunar path.

first is the sun, which is the source of light and heat, then there is the earth, this is what we live on, then is the moon, the moon enters this eclipse faze near a 75 degree angle just behind the earth, then leaves the umbra around 110 then the penumbra around 140 degrees.

usually this is during the night so it is rarely seen.

sorry no Explanations but I got it right on my unit test. Hope you have good  rest of you day.

youre right there are

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
