Answer: Tension
Explanation: Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust. Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle.
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.
25% display the just one trait : 50% display the co-dominant trait : 25% display the just the other trait
For example: a cross of a pink flower and and another pink flower where white and red are co-dominant
25% white : 50% pink : 25% red
