Answer:
These islands represent Europe, Africa, Antarctica, Asia, North and south america etc.
Explanation:
An artificial island or a man-made island is an island created by natural means that vary in sizes.
For example Flevopolder in the Netherlands which is an artificial island of 970 kilometers created for reclaiming the land area as the Netherland already is a very small island in the Atlantic ocean.
Lots of islands are formed by China, America, and the middle east to increase their dominance over and increase their military size. Likewise, <u>U.A.E is home to several artificial islands including yas island and Khalifa port. </u>
China has developed its island group in the south china sea. Which is china's strategic planning to meet its population and economic needs of the country. The biggest world island is that in world map form around which small islands are constructed called as Artificial Archipelago, located in the waters of persian gulf.
Construction of these 300 island began in 2003, this project ranges from 14,000 to 42,000 square meters in area. Comprise of sand and stones The islands have beach clubs and airport.
Answer:
b. increased temperatures
Explanation:
- The primary reason for the productivity in the Photo zones is due to the influence of major factors like the Nutrients, light, and grazing of animals. The rate at which the plants are eaten by herbivorous.
- Upwelling of cool, water from the bottom and interaction of warm waters from the above that derives nutrient-rich water to the surface. These upwelling can be consciously be caused by the winds and the depth of light penetrates down the layer of the water.
- As the intensity of water decrease with depth and with the concentration of nutrient the photic zone becomes shallower.
Answer:
Super position
Faunal Succession
Crosscutting Relationships
Inclusions
Explanation:
Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
Faunal Succession: Similar to the law of superposition is the law of faunal succession, which states that groups of fossil animals and plants occur throughout the geologic record in a distinct and identifiable order. Following this law, sedimentary rocks can be “dated” by their characteristic fossil content. Particularly useful are index fossils, geographically widespread fossils that evolved rapidly through time.
Crosscutting Relationships: Relative ages of rocks and events may also be determined using the law of crosscutting relationships, which states that geologic features such as igneous intrusions or faults are younger than the units they cut across.
Inclusions: Inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating. Inclusions are useful at contacts with igneous rock bodies where magma moving upward through the crust has dislodged and engulfed pieces of the older surrounding rock.
Natural ecosystems are able to maintain a vibrant diversity of life because they incorporate intricate recycling systems that conserve essential materials.
