A pneumonic device is a memorization tool that helps you remember things. For example, if you can read music you probably have heard, “Every Good Boy Does Fine” to learn the names of the lines on the treble clef EGBDF. Or maybe your math teacher taught you, “Please Excuse My Dear Aunt Sally,” to help you remember the order of operations. It is now your turn to think of a pneumonic device to remember the water cycle in order. Write your pneumonic device below.

the figure shows the great ocean conveyor belt. which best describes what this model represents?
A. The model shows how ocean currents change the salinity of water.
B. the model shows how ocean currents move heat energy around earth
C. the model shows how salinity of water affects its density
D. the model shows how the density of water differs between the north Atlantic and other parts of the ocean.
Answer:
d
Explanation:
The ocean conveyor belt shows the movement of the oceanic water and the salinity. The model represents the density of the water in different regions of the world. Thus, option d is correct.
What are ocean conveyor belts?Ocean conveyor belts are the oceanic current movement in their oceans across others and how the water moves across the water bodies across the globe.
The model shows that high salinity water gets heavy and sinks in the ocean of North Atlantic but the water of the Indian and the pacific oceans are less saline and remains at the surface.
Therefore, option D. the water differs in oceans based on density.

What causes water pollution?
Answer:
Good answer below, just adding on
Explanation:
Runoff of chemical products, animal waste, and especially human waste products such as different types of trash like scrap metals and plastic greatly increase water pollution. Additionally, oil leaks and spills can also lead to severe water pollution. As a general statement I'd say that human activities that are not monitored and are either directly dumped into water ways or are caught in run off cause water pollution.

when salt dissolves into water does it change its state
Answer:
no it doesn't change back
fine here When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion).

How is a mixture such as a plate of pasta different from a mixture such as air
Answer:
Well there is a lot of differences between the two. Its called homogeneous and Heterogeneous mixtures. Homogeneous mixtures are all the substances are evenly distributed throughout the mixture (salt water, air, blood). Heterogeneous mixtures are the substances that are not evenly distributed (chocolate chip cookies, pizza, rocks). So Pasta with sauce and meatballs is heterogeneous and air is homogeneous

Make a prediction for what science and technology may uncover in the next few decades.
My prediction for what science and technology may occur in the next few decades is the increase of groundwater increasing, with many drought occurrences to the environment. For technology, I suppose that there may be some new inventions for both political and environmental usage to increase the intensification of agriculture in order for us to have crops to eat. Furthermore, I predict that our significant key issues are resolved as time goes on, such as global warming, inflation, ocean acidification, etc.
