Answer: The answer is C.
Explanation: Soil includes 40-45 percent inorganic matter, 5% organic matter, 25% water, and 25% air. The right combination of air, water, minerals, and organic matter is essential for plant life to thrive. Microorganisms (both dead and alive) and decaying plants make up humus, the organic stuff in soil.
Answer:
C. shallow and occur in the upper 15 to 20 km of crust, even though the San Andreas fault cuts through the crust to deeper depths.
Explanation:
Earthquakes in California usually occur in the upper 15 to 20 km of crust. This is the case even though the San Andreas fault cuts through the crust to deeper depths. The San Andreas fault extends roughly 1,200 kilometers through California, and it forms the tectonic boundary between the Pacific Plate and the North American plate. It is believed that there is significant risk of a major earthquake (greater than 7.0) along this fault, particularly in the southern section of the fault, which is the region along Los Angeles.
Answer:
The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.
Explanation:
It is 4.5 billion years that Earth has been formed and there have been changes since then. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
