They are called fringing reefs. They grow directly from shore and form borders along the shoreline.
When a fringing reef continues to grow upward from a volcanic island that has sunk entirely below the sea level, an atoll is formed. Atolls are usually circular or oval in shape, with an open lagoon in the center.
The fringing reef is the most common type of coral reef. They however tend to be very sensitive to human induced pollution in the water and are easily destroyed by such.
It is called surface currents.
Hello There! ^_^
Your question: Which one of the following times would be the longest..?
You answer: The Paleozoic Era would be the longest time span.
the answer is option B.
Hope this helps!
B = 0.4
b = 0.6
Explanation:
From the question we derive that;
BB = 16%
Bb = 24%
The gene frequency for BB = 16/100 = 0.16
To find allelic frequency of B;
B = √0.16 = 0.4
Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;
p + q = 1
If p = 0.4
q = 1 – 0.4 = 0.6
b = 0.6

Answer:
Regions with a higher amount of rainfall are those of equatorial regions and those of the low rainfall are polar areas.
Explanation:
- The regions in the tropics and the subtropics receive a significant amount of rainfall while the place at the places receives only 10 inches f rainfall and regions are dry annually with rain occurring only in summer.
- The tropical areas are those that surround the earth equator and are found 23 degrees north and south. As the sun is usually in direct contact and this region comprise of 40% of the surface area and 35% of the earth's landmass. And remains warm to hot and moist year-round.
- These regions are characterized by wet season and thus have most of the cyclonic activity through the year and this impacts the global distribution of water as the movement of the warm and cold water stakes form these regions, along with the variation in salinity.
