Answer: A.Santa Ana
Explanation:
This description perfectly agrees with the Santa Ana Winds (also called Santana Winds), which are due to a meteorological phenomenon that occurs between southern California and northern Baja California during autum and early winter (although they can also occur in the other seasons of the year). In this sense, strong winds are caused by high air pressure circulating clockwise at high altitudes in the Great Basin between Sierra Nevada and the Rocky Mountains (and the Mojave Desert).
It should be noted that these winds are characteristic of the region, which dry the vegetation, knock down electric utility poles and trees, and sometimes transport hot embers, being the main cause of fire spread.
Answer:
In a divergent plate boundary, two plates move away from one another. Due to this divergent movement of plates, seafloor spreading takes place in the ocean basin along the mid-oceanic ridge and rifting take place in the continental areas. Due to the stretching of the crust, the lithosphere becomes thin, and with more progressive spreading, it results in the eruption of magma at the seafloor. This magma is basaltic in nature, that reaches the surface due to the force exerted by the uprising magma forming convection cells in the mantle. This type of plate motion results in the expansion of the ocean basin and the rift valley in the continental areas forms seas and oceans with increasing time.
The rocks that are formed at the mid-oceanic ridge are the youngest as the magma cools and solidifies very rapidly here. With further moving away from this spreading center the age of the rocks increases.
The divergent plate boundaries are also responsible for the occurrence of deep-focus earthquakes, and it also leads to the formation of volcanoes in its adjacent sides.
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True, because it happens with landslides and other causes.
No fossils from the Precambrian era have been found because there were no organisms at the time: False because there were organisims like algae and bacteria, and there are a very small amout of fossils from that era.
The map of Earth has changed over millions of years, but is now set: False
Answer:
SO2 and NOx
Explanation:
The oxides of Sulphur and Nirogen are the major constituents of acid rain. These oxides combine with the water vapor present in the atmosphere and form sulphuric and nitric acid and thus it rains acid.
The region of the United States most harmed by acid rain is the East Coast, including the Appalachian Mountains and the Northeast. In India the Agra Taj Mahal color is changing from white to Yellow because of acid rain. Acid rains are harmful for are agricultural land as well.
