- President Nayib Bukele and his majority in the Legislative Assembly have systematically dismantled democratic checks and balances. In October, despite a constitutional prohibition on immediate re-election, Bukele registered as a candidate for the 2024 general elections. In November, the assembly granted Bukele a six-month leave of absence from the presidency and named Claudia Rodríguez, the current head of the National Directorate of Municipal Works, as his substitute.
- Sedimentary rock (Wikipedia)
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution.
