Answer:
Cation-exchange capacity is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules, but allow these to exchange with other positively charged particles in the surrounding soil water
G...eventually the larger fish would catch on that these smaller fish are a problem.
Answer:
a The volume of the liquid should be measured before it is heated.
Explanation:
A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increase in volume. The following list shows the steps taken by the student in order to test the hypothesis.
Select the liquid to test.
Place the liquid in a sealed container.
Use a Bunsen burner to heat the liquid by 10°C.
Measure the volume of the liquid.
Record the results.
What is wrong with how the student conducted the investigation?
a The volume of the liquid should be measured before it is heated.
b The hypothesis was not valid because it is impossible for liquids to change in volume.
c The student should have increased the temperature of the liquid by more than 10ºC.
d The length of time it took for the liquid to be heated should be measured.
The answer is A i.e The volume of the liquid should be measured before it is heated. I think this is surely right!!
<span>Which storm is likely to cause quick destruction along a narrow path?
</span>
<span>A.tornado
B.hurricane
C.thunderstorm
Your answer would be a A.Tornado
</span>
<span>Which clouds are best associated with a thunderstorm?
A.high cumulonimbus
B.towering funnel clouds
C.swirling clouds with a calm center</span>
Thunderstorms occur in association with a type of cloud known as a cumulonimbus. So, <span>A.high cumulonimbus
</span>
<span>Which statement best describes the formation of a hurricane?
A.Air pressure differences over the ocean cause fast, spinning winds.
B.An updraft of warm, moist air builds a cumulonimbus cloud.
C.A downdraft of air meets spinning updrafts.
</span>
Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
<span>A.Air pressure differences over the ocean cause fast, spinning winds.
</span>
<span>How are hurricanes and thunderstorms similar?
A.Both cover an area as large as 650 km.
B.Both involve the formation of large cumulonimbus clouds.
C.Both form when warm air rises, then cools quickly to form clouds.</span>
Hurrica<span>nes and thunderstorms are both convective storms fueled by warm, moist air. </span><span>C.Both form when warm air rises, then cools quickly to form clouds.
</span><span>Is this statement true or false?
Hurricanes are classified by three stages in which updrafts of air
billow up, updrafts and downdrafts swirl the wind up and down, then
downdrafts cause clouds to come apart.
A.True
B.False
This would be true
</span>
<span>Which severe weather condition forms over warm, tropical areas?
A. tornado
B. hurricane
C. thunderstorm
</span>
Thunderstorms result from the rapid upward movement of warm, moist air. They can occur inside warm, moist air masses and at fronts. As the warm, moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of over 12.45 miles.
Hurricanes develop in warm, tropical regions where the
water is at least 80 degrees Fahrenheit The
storms also require moist air and converging equatorial winds.
A tornado can form where winds blow at
different speeds causing rotation which can tighten and speed into a
funnel cloud if caught in the flow of air moving into the storm.
Rain and hail can cause the funnel to bend downward.
<span>B. hurricane is your answer
Hope it helped :)
