Answer:
The high islands of the Pacific were formed by seismic activity whereas the low islands of the Pacific were formed by coral growth. Continental islands and oceanic islands were formed by volcanic activity.
High islands often have fertile soils and lush rainforests. In contrast, low islands are often less fertile than high islands. Some low islands lack freshwater sources.
The answer is A:) Shorelines
Answer:
active margins :- g. mid-ocean ridge, a. formation of igneous rock, b. submarine lava eruptions,
passive margins:- d. gentle continental slope, f. few or no earthquakes, h. continental rise, k. broad continental shelf, l. can be adjacent to thick continental crust, j. formation of sedimentary rock
both:- e. accretionary prism, c. trench etc.
Explanation:
- An active margin is found at the leading edges of the continents where it collided with the oceanic plate. It is commonly the site of tectonic activity. Earthquakes volcanoes and the mountain building and the formation of new igneous rocks.
- While the passive margins include the continental rise abyssal plains and few or nor earthquake. formation of sedimentary rocks. Broad shelves and thick crust.
idk the answer but i think u can find it on quizlet
The following is a point source of water pollution :
<u>Offshore oils wells</u>
Explanation:
- Offshore drilling is a mechanical process where a wellbore is drilled below the seabed.
- Oil platforms that are in the middle of the sea have two ways of transporting the oil to land, depending on how far it is from land.
- The way of transporting is via oil tankers. Empty tankers sail to the oil platform, get filled up with oil, and sail back to land.
- Pipelines running from offshore rigs to inland processing facilities can worsen water quality in estuaries and increase the likelihood of oil spills across beaches, according to the report. In addition, toxic waste brought onshore from drilling operations can pollute drinking water and tracts of land
- Drilling mud or seawater provides the pressure to hold the plug in place while the engineers place a top plug to cap the oil well. Then the well is ready for a production rig to take over. Offshore production rigs work in a similar way to land-based oil rigs.
