When silicon atoms bond, then silicates form which are minerals in which such elements as potassium, calcium, magnesium and aluminum combine with the silicon atoms to form minerals like feldspars of different types or if it is just silicon and oxygen that bond then it forms quartz.
Floods are the most frequent type of NATURAL DISASTER and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
Floods can cause widespread devastation, resulting in loss of life and damages to personal property and critical public health infrastructure. Between 1998-2017, floods affected more than 2 billion people worldwide. People who live in floodplains or non-resistant buildings, or lack warning systems and awareness of flooding hazard, are most vulnerable to floods.

Answer:
D. Ocean - Atmosphere - Wind - Weather
Explanation:
- The El Nino (warm) and La Nina (cool) are the opposing phases of climatic patterns in the tropical pacific ocean and take place every 3 to 7 years. Combined they are called ENSO.
- First, in the El Nino ocean temperatures in the eastern tropical pacific ocean rise above average and this leads to rainfall over Indonesia and storms in central pacific. This rising air increases the air motion and leads to dryness and high surface pressure during the La Nina phase this condition gets reversed.
- During the El Nino, the northwestern pacific tends to be warmers and the southern tier of California tends to be cooler and wetter. These surface temperatures are caused and changed by the help of trade winds. These blows from east to west along the pacific ocean.
- These phenomena thus influenced the weather along the western and the eastern pacific ocean.
