At about 9.30 on August 21, 1986, rumbling sounds lasting 15-20 seconds brought people out of their Cameroon homes in the small village of Nios. Not minutes after, a lethal gas cloud pooled out of nearby Lake Nyos and spread over the town. People reported smelling an odor like rotten eggs or gunpowder, felt a warm feeling, and quickly lost consciousness. Survivors, who woke 6-36 hours, felt disoriented and weak, and found that their friends and family were all dead. About a day later began the…

In this set of materials, the reading passage tells us about the three types of rock, and the listening passage explains the additional usage of sedimentary rock, which is describing as a third rock in the reading passage. The reading passage informs us about the characteristics of the three rocks. The most common rock is Igneous rock which means fire. The example of it is granite. By cooling and solidification of lava, igneous rock will be formed, and this makes up approximately 64.7% of the…

A giant is born from the depths of the ocean, a catastrophe waiting to happen. As hot magma bubbles up from the depths of the earth, it pushes through the surface and Krakatoa is born. The 1883 eruption of Krakatoa was devastating. The resulting toxic gases, deadly pyroclastic flows, and giant tsunamis are astonishing. The eruption of Krakatoa was the loudest eruption ever heard in history. Krakatoa is located in the Sunda Strait between Java and Sumatra in Indonesia. The island of Krakatoa is…

A Poem in relation to Natural Selection When one thinks of a giant crack of lighting whitening the sky or the massive roaring of an erupting volcano, the first thing that might befall their mind is violence and destruction. Watching the wrath of mother nature before your eyes can be disheartening. Several movies have depicted her power such as San Andreas (2015), and Geostorm (2017). While these movies are fictional they do display how terrifying nature can be to the frailty of life.…

Introduction Brahmaputra River, the peculiar drainage pattern of large Southeast Asian rivers, reflects a complicated tectonic history of crustal deformation in the Himalaya and river re-organization. In general, the Himalayas are divided into three tectono-lithologic domains: the Lower Himalayas, the Higher Himalayas and the Tethys Himalayas (Amano and Taira, 1992); surprisingly this river flows through over these three domains (Fig.1). The mineral assemblages are correlated with these…

Lahar is an Indonesian word with its English alternative or equivalent being Lava. That said, it suffices to say Lahar is a volcanic mudflow. That being the case, for a flow to occur, there has to be a slope or a driving force, otherwise it will be stagnant. Because a slope is involved you would expect lahars to be ubiquitous in mountainous terrain. The best case scenario to depict how a Lahar looks like is to picture a mixture of concrete and water moving down a slope at a great speed…

I believe that there are no plate tectonics on Venus. I believe this because of the reasearch that i did on this topic. Venus shows no evidence of plate tectonics on it's planet. " There are no long, linear volcano chains or any clear subduction zones. The transform plate boundary, causes the plates to slide past one another, which may cause earthquakes or fault lines, which is exactly what is happening. The plates are sliding past one another and earthquakes ar occuring which may lead one to…
