Questions on tectonic plates, could someone help?

What types of geological events or changes occur at divergent plate boundaries?

What types of geological events or changes occur at convergent plate boundaries?

What types of geological events or changes occur at transform plate boundaries?

Explain how these geological processes and interactions have changed Earth's surface through the years. Be sure to use evidence to support your answer.

Answers

Answer:

1) A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

2) A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction) This can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

3) In a transform plate boundary, two plates slide past each other, conserving the plates. Shallow-focus earthquakes are generated here. The earth has experienced various geological processes, such as weathering and erosion of rocks, earthquakes, volcanic eruptions, mass extinction events, plate tectonic movements.

4) these geological processes and interactions have changed Earth's surface through the years by causing more geological processes such as "earthquakes, volcanic eruptions, and mass extinction events" these changes have also "created a new oceanic crust" stated by the NOAA

Explanation:

Deng Xiaping's reforms aimed to bring more economic freedom to China.

What is Deng Xiaoping?

Deng Xiaoping was a Chinese revolutionary leader, military commander and statesman who served as the paramount leader of the People's Republic of China from December 1978 to November 1989. After Chinese Communist Party chairman Mao Zedong's death in 1976, Deng gradually rose to supreme power and led China through a series of far-reaching market-economy reforms earning him the reputation as the "Architect of Modern China".

He contributed to China becoming the world's second-largest economy by nominal GDP in 2010. Born in the province of Sichuan in the Qing dynasty, Deng studied and worked in France in the 1920s, where he became a follower of Marxism Leninism and joined the Chinese Communist Party in 1924.

In early 1926, Deng traveled to Moscow to study Communist doctrines and became a political commissar for the Red Army upon returning to China. In late 1929, Deng led local Red Army uprisings in Guangxi.
