<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:
In 1849, Californians sought statehood and, after heated debate in the U.S. Congress arising out of the slavery issue, California entered the Union as a free, nonslavery state by the Compromise of 1850. California became the 31st state on September 9, 1850. ... California situated its first capital in San Jose.
The northern boundary was set along the 42nd parallel. The southern boundary had already determined by the Treaty of Guadalupe-Hidalgo with Mexico. The northeast corner of the state would be the point where the 42nd parallel met the 120th meridian, to include the Sierras.
