2.8 Main Cause of Flood According to Jabatan Penerangan Malaysia (2012), issues of flood that happen certainly had their own causes. There are many causes such as: 2.8.1 Continuous Rain Continuous rain without stopping can cause flooding. In low areas, rain water will flow into the river. River filled with water will overflow causing lowland area are flooded. 2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills
A Study on Past and Future Limnic Eruptions Written by Lauryn Noyes Science and History A limnic eruption is an extremely rare, and fatal natural disaster that requires an unusual set of circumstances. To date, 2 separate documented volcanic eruptions have occurred. They were both fatal, happened in 1984, as well as 1986, and were within 60 miles of each other. In order for a limnic eruption to occur, you must first have a meromictic maar. A meromictic lake is a lake that has layers of water that
Why does fizzy drinks react to mentos the way they do and what drink will create the most significant reaction? Introduction Have you ever seen what happens when you put Mentos in fizzy? Did you ever wonder what caused this reaction? Well today that's what we are doing, the point of our experiment is to find out what and how the reaction is caused and what fizzy drink will cause the biggest reaction Aim. We aim to find out which of our three carbonated drinks (Diet Coke, Fanta, and Sprite) can
What causes Diet Coke and Mentos to react to make big fizzy explosions? One of the most popular theories is a process that is called nucleation, it’s happens when carbon dioxide in the soda is attracted to Mentos. It creates pressure that builds up until the soda explodes and goes flying! The reason it bubbles up so much is that it has thousands of tiny little pores on the surface that interrupts the polar attractions between water molecules, making thousands of nucleation sites in the soda to group
Nevado del Ruiz Case Study The Eruption and its Impacts What happened? On November 13th, 1985, the Nevado del Ruiz volcano erupted triggering destructive lahars, which caused approximately 23 000 human deaths, 4500 were injured and, following the catastrophe, 8000 became homeless [3]. Signs of seismic activity can be traced back to July of the same year, where seismograph on the mountain showed uncharacteristically seismic activity levels [1]. Later, in September 1985, not only had the level of
August 1986 in the northwest region of Cameroon, Africa, Lake Nyos released a cloudy mixture of carbon dioxide and water droplets which had a height of 100 meters. Carbon dioxide is odorless and heavier than air which can suffocate any mammal. A limnic eruption is a natural disaster that happens when dissolved carbon dioxide suddenly erupts from deep lake waters, forming a gas cloud that can suffocate wildlife, livestock, and humans. When Lake Nyos erupted, the fog killed all living things within a 25km
