PLEASEE ANSWER BEFORE FRIDAY APRIL 30 Seven students looked at a barometer, a weather device that measures air pressure. They had different ideas about air pressure. This is what they
thought:
Kimberly:
Glenn:
Rae:
Jeff:
Oliver:
I think air has to be moving to create air pressure.
Air pressure is a downward force.
The higher in the atmosphere, the greater the air pressure.
Air pressure is the same in all directions.
Air pressure increases as the number of air particles increases.
Warm air masses have higher pressure than cool air masses.
When air pressure decreases, it might rain or snow.
Cameron:
Jay:
Circle the names of the students you agree with and describe why you
agree. Describe your ideas about air pressure.
Answers
Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.

What is the weather forecast?Utilizing science and technology to forecast the atmospheric conditions at a certain area and time is known as weather forecasting. Weather forecasting has been done sporadically for millennia and formally since the 19th century.
Meteorology is used to predict how the atmosphere will change at a certain location while quantitative data about the state of the atmosphere, land, and ocean are gathered to provide weather forecasts. Weather forecasts can be used for a huge range of purposes. Weather warnings are crucial forecasts because they serve to safeguard property and human life.
When temperature increases, pressure decreases. Hence, The measurement shows high temperature and low pressure.

A population is a group of individuals of the same species. According to the theory of natural selection, what is likely to happen to a population when a change occurs in its environment (for example, the amount of rainfall decreases or the temperature increases)?
A.All of the individuals would try to develop new traits so that they could survive and reproduce in the changed environment. B.Some of the individuals would try to develop new traits so that they could survive and reproduce, and the other individuals would die. C.Because all individuals of the same species have the same traits, one individual would never have an advantage over another in its population.They would either all survive or all die.D.The individuals that have traits better suited to the changed environment would be more likely to survive and reproduce than those with less suitable traits.
Answers
Answer:
The answer is D.
Explanation: As everyone knows, "survival of the fittest" is a common thing. When an environment is disturbed or has some changes, the effects vary from one species to another and the ones who have traits that can help get through or adapt to these changes will most likely survive.

Explanation:
A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene.

After studying plate tectonics, Lee became interested in mid-ocean ridges and how rock develops as the tectonic plates spread apart, so he decided to investigate further. Which of the following statements are true about sea-floor spreading? Choose the three statements that apply. A. Young rock forms in layers on the ocean floor as spreading occurs. B. Magma flows through cracks in Earth's crust and hardens. C. Continental crust is formed by the ridges as they grow. D. Mid-ocean ridges are the sources of the spreading. E. Older rock is farther away from the mid-ocean ridges.
Answers
Answer:
A, B, E
Explanation:
The magma rising through the cracks makes new younger rocks close to the crack as the magma follows out and hardens. This means that rocks farther away from the crack are older because they where formed when they where right next to the crack. They are father away meaning they got pushed back as time went on.
Mid ocean ridges are a result of the spreading not the cause.
Because they are in the middle of the ocean and they are moving constantly i dought the mid ocean ridges are creating continents.
Young rock forms in layers on the ocean floor as spreading occurs, magma flows through cracks in Earth's crust and hardens, and older rock is farther away from the mid-rock is farther away from the mid-ocean ridges. Thus, the correct options are A, B, and E.
What is Sea-floor spreading?
Seafloor spreading is a geologic process in which the plate tectonic and large slabs of the Earth's lithosphere split apart from each other in space. Seafloor spreading and other tectonic activities are the result of mantle convection, which is a slow, churning motion of the Earth's mantle.
The magma in the Earth rise through the cracks in rocks that makes new younger rocks which are close to the crack as the magma follows out and hardens. This means that rocks which are farther away from the crack in the rock are older as they were formed when they were right next to the crack.
Mid ocean ridges are formed as a result of the Seafloor spreading. Because they are present in the middle of the ocean and are constantly moving in the mid ocean ridges which create continents.
Therefore, the correct options are A, B, and E.

Global warming occurs because of increased greenhouse gases such as carbon dioxide in our atmosphere. Carbon dioxide forms carbonic acid when dissolved in water. The increase of carbonic acid in the ocean waters prevents sea creatures from making bones and shells. Based on the informationabove which of the following statements best explains what would occur. A.The ocean water would change its current so that the acidic water is relocated to another area and allow plankton and sea coral to survive. B.The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow plankton and sea coral to survive. C.Plankton and sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment. D.Plankton and sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

How coral can survive in acidic environment of ocean?
Plankton and sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment because of the acidic pH of water is destroying their body. If they can't mutate their selves, they will be killed and totally removed from the ocean.
So we can conclude that option D is the correct answer.

When the tide goes out, where does the water go?
Answer with at least two complete sentences.
Be sure to check your grammar and spelling.
You can use the sentence starters below to help you answer:
When the tide goes out, the water ________________________.
Answers
Answer:
When the tide goes out, the water retracts back into the sea. The water moves between the sun and the moon which pulls the water back into the sea.
Explanation:
Tides are caused by the gravity of both the moon and the sun “pulling” at the water in the sea. Because the Earth is constantly turning, the “pull” of gravity affects different places as each day goes on - so when the tide is “out” in your area, it is “in” somewhere else.
