Describe the phenomena in the images and what impacts Earth might experience from increased solar radiation.
Answer:
Explanation:For any given spot on earth, solar energy is affected by:
Time of day.
Distance from the sun.
Angle of the sun off of normal.
Cloud cover.
Pollution.
Intensity of the sun, it varies slightly.
The amount of solar energy that reaches the earth is depended on our position in orbit. We have an elliptical orbit and receive more sunlight during the winter than summer, but only slightly so.
How much sunlight reaches the surface (solid ground or sea level) is dependent on the amount of particulate is in the atmosphere (soot, smoke, pollution, etc.), and how much ozone, water vapor, CO2, fluorocarbons, nitric oxide and the like are present. These latter block some sunlight or absorb some solar energy warming the upper atmosphere but also reflect infra red radiation back towards the surface (global warming). ozone, water vapor and CO2 are essential for the existence of life on earth, but the ratio and amount of each have been in a delicate balance that created the climate we have and promoted the wonderful eco-system we have enjoyed for the last 75,000 years. Human activity has disrupted that balance and now threaten to radically change our climate.

does the temperature increase or decrease with altitude in the stratosphere?
Answer:
yes the temperature increases or decreasesdifferentiate between the formation of biochemical rocks and the formation of inorganic chemical rocks.
Answer:
biochemical rocks form from organisms that were once alive whereas inorganic rocks form from non-biological processes.
Biochemical rocks and inorganic chemical rocks contrast in their starting point and sythesis.
Biochemical rocks, similar to limestone, are framed from the aggregation and cementation of natural materials, frequently the remaining parts of marine living beings like shells and coral reefs. Conversely, inorganic chemical rocks, for example, rock salt and gypsum, emerge from the precipitation of broken up minerals from water, frequently in bone-dry or evaporative conditions.
The previous depends on natural cycles for its constituents, while the last option begins from non-living synthetic responses. This differentiation features the job of creatures in molding the structure of biochemical rocks, while inorganic chemical rocks result from abiotic processes.

Spinning ______ inside wind turbines create electricity
Answer:
ShaftsExplanation:
Like bigger wind turbines, home turbines harness the energy of the breeze to turn it into electricity. When the wind blows, it pushes the blades of the turbine and makes them spin. This spinning turns a shaft inside the turbine, which powers a generator, which turns the kinetic energy of the spinning motion into electricity.

10. Compare the events in the life of the Sun with those of a star that starts with a mass 10 times greater than the Sun's.
Answer:
A star that has a greater mass will die out faster.
Explanation:
The reason for this is because the star would need to use up and burn more energy therefore speeding up it's life process.
A star that has a greater mass will die out faster.
Why will the star die?A star's life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion.
Sun and starsOur Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. The Sun is composed almost entirely of hydrogen and helium gas.
Thus, one comparison in the events in the life of the Sun with those of a star that starts with a mass 10 times greater than the Sun's is a star that has a greater mass will die out faster.
