Describe how a coral atoll forms. What will be an ideal response?


A fringing coral reef forms around an island, usually a volcano. As the oceanic plate moves away from
the spreading center or volcanic hotspot, the plate cools and becomes less buoyant and sinks. The coral
continues to grow upward but the island erodes and disappears below the surface. The coral remains as
a circular atoll.

Increasing temperatures of earth’s surface and lower atmosphere provide strong evidence that global

warming is happening right now. This evidence includes all of the following except:a. Average earth temperature from land areas and global shipping lanes indicate that average Earth temperature increased 0.74 degrees Celsius during the 20th century. b. Half of the increase in Earth’s average temperature from the 20th century increased during its last 30 years. c. Nine of the ten years during the first decade of the 21st Century were in the top 10 warmest years of a 160-year-long record. d. Earth’s present average temperature is the warmest it has been since 1400, which is as far back as we can go with certainty by direct and indirect evidence. e. During the recent increase in Earth’s temperature the greatest amount of warming occurred during the day near the equator.
