Nebular theory was formulated by Laplace which describes the formation of the Sun and solar system. Laplace along with his colleague John Michel, introduced the idea of a “dark star,” which later came to be called as black hole.

Notes:
Pebble transport by rivers, sand drift over desert surfaces, soil blowing over fields are examples of saltation. Saltation is a type of particle transport by fluids such as wind or water.

Notes:
Quartzite is formed by the recrystallization of silica found in sandstone. Quartzite is a hard, non-foliated metamorphic rock that was originally sandstone. The transformation from sandstone to quartzite happens through recrystallization. The heating and pressure that causes the transformation is usually related to tectonic compression within orogenic belts.
Quartzite is composed almost entirely of quartz. The quartz grains from the original sandstone are enlarged and interlocked by recrystallization. Quartzite does not tend to be foliated because quartz crystals don’t align with the directional pressure.

Notes:

Also, the continuous military exercise of the Chinese People’s Liberation Army-Air Force (PLAAF) over the channel, which is the waterway connecting the South China Sea with the western Pacific Ocean, between Taiwan and the Philippines, has kept it in limelight.
