Fansipan (Vietnamese: Phan Xi Păng, listen ⓘ) is a mountain in Vietnam. Its height was 3,143 metres (10,312 ft) in 1909, and it presently stands at 3,147.3 metres (10,326 ft). [ 1 ] It is the highest mountain on the Indochinese peninsula (comprising Vietnam, Laos , and Cambodia ), hence its nickname, "the Roof of Indochina".

Geologic time shown in a diagram called a geological clock, showing the relative lengths of the eons of Earth's history and noting major events The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale , a system of chronological measurement based on the study of the planet's rock ...
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 251.9 Ma and 247.2 Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era.
According to evidence from radiometric dating and other sources, Earth formed about 4.54 billion years ago. [7] [8] [9] The current dominant theory of planet formation suggests that planets such as Earth form in about 50 to 100 million years but more recently proposed alternative processes and timescales have stimulated ongoing debate in the planetary science community.

The climate alternated between warming and cooling periods; overall the Earth was hotter than it is today. Bony fishes remained largely unaffected by the Permian-Triassic extinction event. [80] The Mesozoic saw the diversification of neopterygian fishes, the clade that consists of holostean and teleost fishes. Most of them were small in size. [80]
The unique shape of the Gulf of Mexico, surrounded on all sides by continental crust, is the result of two different tectonic boundaries: an ocean-continent transform boundary, and a magmatic plume fueled seafloor spreading center active contemporaneously in regards to geologic time. The transform boundary caused two approximately 22 ...
This glaciation eventually coalesced into the kilometers-thick ice sheets seen today. [55] Other major events took place during the Cenozoic, including the opening of the Gulf of California, the uplift of the Alps, and the opening of the Sea of Japan. The break-up of Pangaea continues today in the Red Sea Rift and East African Rift.
