D.Weak winds that blow for a long time over a great distance.
Answer: the answer is C
Explanation:
Answer:
c!
Explanation:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water
•more slowly
•at the same rate
•more rapidly
Answer:
more rapidly
Explanation:
Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.
According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

How do scientists learn about the age of the solar system and its planetary bodies? Select the two correct answers.
a. comparing the composition of the gaseous planets to the rocky planets
b. using radiometric dating of meteorites
c. measuring distances between planets
d. analyzing impact craters on planetary body surfaces
Answer: B, C
Explanation: Scientists use radiometric dating of meteorites and analyze the impact craters on planetary body surfaces to learn about the age of the solar system and its planetary bodies.
Using radiometric dating of meteorites and analyzing impact craters on planetary body surfaces are the two methods that tells us about the age of solar system.
The age of solar system and its planetary bodies can be find out by using radioactive dating techniques. Scientists have find out that the Solar System is 4.6 billion years old due to this technique. The other way to find out the age of solar system and its planetary bodies by counting the number of impact craters occurs on planetary body surfaces so these two methods provides information about the age of solar system and its planetary bodies

Write 5-6 sentences about snakes. (This is for an informational paper, make if formal!) Please don't put links/files to download because I can't download on this computer since it is the family computer. THANK YOU!
Answer:
Hi, I can help you!
Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[
