<u>Answer:
</u>
The process of thick sediment layers to "accumulate" along the "boundaries of continental and oceanic plates" is called Subduction.
<u>Explanation:
</u>
- During a marine transgression, sea level raises high compared to land level resulting in floods. These are triggered during climate changes, ice-age, isostatic movements.
- Subduction occurs at the tectonic plates where one plate is moves under another forcing to sink into Earth’s mantle due to the gravitational force.
- The plates are continental and oceanic in the zone of lithosphere. The rate of subduction is usually seven to 8 centimetres per year.
- Marine regressions are opposite to transgressions where sea levels fall compared to land levels.
- Glaciation is the interval of time within an ice-age. The current glacier period is of Holocene.
Answer:
140 years is average duration of an earthquake.
Explanation:
- The Hayward fault is a geologic fault that is capable of massive destruction and is 119 km long fault western base of hills of San Francisco and is parallel to the San Andreas fault. The occurrence of an earthquake of 6.8 magnitudes in 1868 was biggest earthquake in California history.
- Recently various geologists have taken time interval of the past five large earthquakes and based on the past earthquakes data the interval of 140 years it will take to the formation of a large earthquake.
is about 55 miles at its narrowest point. so around 50 miles would be the answer.
