Explain how the ozone layer forms, how human activities have damaged it, and the consequences of the destruction of the ozone la
Vikki [24]

Answer:

Ozone is formed in the stratosphere naturally.

High energy solar radiation strike the oxygen atoms O2, the two atoms split apart. The freed atom collides with another oxygen atom O2 forming O3 (Ozone)

Ozone layer is destroyed when chloroflourocarbons and halons.

CFCs and halons cause chemical reactions that break down ozone molecules. Consequences ofnozone depletion are that UV radiations are not filtered and they reach the earth causing damage to eyes and skin.

Explanation:

Ozone layer is a protective layer which protects from UV damaging radiations. It is formed when oxygen atoms are broken down by photolysis and a freed oxygen atom combines with another amd form O3.

Ozone is being depleted now because chlorofluorocarbons (CFCs) and halons—gases found in aerosol spray cans and refrigerants—are released into the atmosphere they decrease the ozone's ultraviolet radiation-absorbing capacity.Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include skin cancers, eye cataracts and immune deficiency disorders.

(GIVING BRAINLIST) 5TH GRADE I NEED HELP ASAP. in the space provided, describe how the intestines, liver, stomach, and pancreas
umka21 [38]

Answer: Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

Explanation:

Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
