Answer: When watching the stars at night, they do appear to move very slowly. This is because the Earth is constantly moving. The Earth completes one “rotation” every twenty-four hours. A rotation is when the planet spins around once. The Earth rotates counterclockwise; this is why the Sun “rises” in the East and “sets” in the West. It is not the Sun’s movement that causes days, but rather the Earth turning around in front of the Sun.
The Earth’s axis (the point at which it rotates around, for example, if you were to spin around while standing in one spot, your axis would be an imaginary line running through your head straight down to your feet) is in line with a star named “Polaris”. Polaris is also known as the “North Star” since it is directly above the Earth’s axis.
Since this star is directly above the Earth’s axis, it does not appear to move, however, the rest of the stars in the sky move around Polaris (for example: when you spin around, the object directly above your head does not appear to move but everything else seems to spin around that object). Polaris is only seen in the Northern hemisphere and it belongs to the Little Dipper constellation (it’s the last star at the end of the “handle”). Another type of motion is known as “revolution”. Revolution is when one object completes a circular path around another object. The Earth takes 365.24 days to revolve around the Sun. This is why a year is 365 days long. During the year the Earth is angled differently towards the Sun. These changing angles provide us with different Sun intensities and therefore we get four different seasons. Since the Earth is at different positions in space over the year, we see different constellations throughout the year.
The model of the globe shows how the earth rotates on its axis and thus creates the effect of rotation hence seasons are the product of the rotational motion.
What is the rotation of the earth?The rotation of the earth takes place once every 24 hours and is in respect to the sun's orbit. Earth rotates in a seemly slow motion and spins on its axis.
The planet thus has night and day and rotational main leads to the different season as earth time counterclockwise the corlis force starts into motion and set the direction of north and south winds.
The effect of rotation varies depending on the tilt of the earth which is 23.5 degrees. Hence the region further in poles receives less sunlight than those on the equator.

A. Toxic gases would be released, causing large-scale pollution.
B. Damage to marine flora and fauna due to oil spills could be prevented.
C. The consumption of nonrenewable energy sources would be increased.
D. The process of oil exploration would become simpler and more economical.
Answer:
B
Explanation:
Damage to marine flora and fauna due to oil spills could be prevented, could be the likely impact of this biotechnology on the environment and the society. Hence, option B is correct.
What is biotechnology?In its simplest form, biotechnology can be defined as biology-based technology that employs cellular and biomolecular processes to produce goods and innovations that improve both human health and the health of the planet.
The four primary industrial sectors where biotechnology is used are health care, crop production and agriculture, non-food uses of crops and other products such biodegradable polymers, vegetable oil, and biofuels, and environmental purposes. The five branch of the biotechnology are human, environmental, industrial, animal and plant, that help sin fighting with the disease.
Thus, option B is correct.

Answer:
The blank is "transform plate."
Explanation:
The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate. The San Andreas Fault is just one of several faults that accommodate the transform motion between the Pacific and North American plates.

California’s San Andres fault is known for its earthquakes. The Pacific plate and North American plate are sliding against each other at this example of a strike-slip fault boundary.
What is Strike-slip fault boundary?Strike-slip faults are the vertical or nearly vertical fractures that occur where the blocks have mostly moved horizontally over each other. If the block opposite an observer, then the fault moves to the right, the slip style is termed right-lateral in this case and if the block moves to the left, the motion is termed left-lateral motion of the block.
The cause of the strike-slip fault earthquakes is due to the movement of the two plates which are against one another and the release of built up strain from these plates. As the larger plates are pushed or pulled in different directions they build up the strain against adjacent plates until it finally fails. The Pacific plate and North American plate sliding against each other is an example of strike-slip fault.

How are some humans using more than their fair share of water? What is the effect of using water on environmental systems?
Please write a full paragraph and cite evidence.
Answer:
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.
