Answer:
c. a densely populated community that only occurs in shallow water near the shoreline.
Explanation:
- The corals are found in shallow and dense waters and reef corals are only formed in the shallow waters and mostly occur in the tropical and the subtropical waters. And occur in colonies of colonies of polyps and held together by the calcium carbonates and are found near the shores and provides protection to the shoreline.
Answer:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
Explanation:
Ice Sheet: Shrinking of ice sheets in a glacier is a result of the burning of fossil fuels that building up greenhouse gases in the environment and leading to global warming. When ice exposes to heat, it shrinks and melts.
Moraine: A moraine is defined as the debris or piles of rock left behind by a moving glacier.
Countour Planting: Contour farming or planting is a farming technique in which plants are grown in row patterns across a slope following its elevation contour lines. It prevents soil erosion by capturing at least twice the rainwater.
Retreating: Retreating is the process in which either ice melts or erode. Continent size can be affected by the retreating ability of glaciers.
Hence, the correct answer is:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
Answer:
C. its age
Explanation:
Rex is most likely trying to figure out the age of the rock formation. It is usually done by comparing the isotopic ratios of the daughter to the parent and their decay rates.
- This is known as radiometric dating.
- Here an exact numerical age of the rock is usually obtained by measuring these isotopic ratio.
- The rate of decay serves as a clock to measure how far the radioactive material has decayed in time
Answer:
1.A fertile area in desert where water is found.
2.This circular geologic feature is thought to be caused by an uplifted dome-geologist would classify it as a domed anticline-that has been eroded to expose the originally flat rock layers.
