- A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.
- Paramount leader (Wikipedia)
Paramount leader (Chinese: 最高领导人; pinyin: Zuìgāo Lǐngdǎorén; lit. ‘highest leader’) is an informal term for the most important political figure in the People’s Republic of China (PRC). The paramount leader typically controls the Chinese Communist Party (CCP) and the People’s Liberation Army (PLA), often holding the titles of CCP General Secretary and Chairman of the Central Military Commission (CMC). The state representative (president) or head of government (premier) are not necessarily paramount leader—under China’s party-state system, CCP roles are politically more important than state titles.
