Formation of Rocks The three main ways rocks are formed: • Sedimentary rocks are formed through the gradual accumulation of sediment: for example‚ sand on a beach or mud on a river bed. As the sediment is buried it is compacted as more and more material is deposited on top. Eventually the sediment will become so dense that it is essentially rock. This process is known as lithification. • Igneous rocks are rocks which have crystallized from a melt or magma. The melt is made up of various components

center of the island. Halla Mountain is recognized as a World Heritage Site by UNESCO with two other tourist site‚ Seongsan llchulbong Peak‚ Geomunoreum Lava Tube System‚ of Jeju. The volcanic activity generated tremendous amount of basalt. People in Jeju used the basalt to create a symbol of Jeju‚ Dolhareubang (it means stone statue of old grandfathers). Moreover‚ Jeju is famous with its beach because of the color of ocean which is similar to the tropical oceans-emerald-like color. Tourist Spots

Plate Tectonics Ever since the beginning on time‚ Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth‚ and possibly of what the Earth may become at a certain point in time‚ has a great influence on understanding all aspects of living things‚ either in the past‚ present‚ or future. The study of Plate

Ancient lineages across the Drakensberg Alpine Centre and their plight for conservation. 1. Introduction: With many recent studies showing that the current global rates of biodiversity loss are cause for alarm‚ it is important to recognize regions in which biodiversity is especially high and under threat from human expansion and climate change. The combinations of biodiversity assemblages along the Escarpment form nodes of high local endemism that have contributed towards the concept of ‘centers

missions and they were surprising to say the least! One of the questions posed by many scientists was what type of geological make up is the moon made up of? They discovered that most of the moon was made up of‚ in fact‚ high temperature rocks such as Basalts‚ Breccias‚ and Anorthosites. This means that the moon had to have had been formed with some solar activity. This helped

The river erosion processes involved in the formation of waterfalls are hydraulic action‚ abrasion and solution. Hydraulic action is the force of moving water on the land. Fast flowing water forces out looses rock and soil from the river bed and bank. Soft rock is eroded faster than hard rock (differential erosion) and overtime the bank will collapse. Abrasion is the wearing away of the river bed by its load. Stones carried by the river smooth the river channel deepening & widening it. Solution

As Earth heated‚ it became partially molten. Thirty to sixty percent of the Earth formed an outer magma ocean that was hundreds of kilometers thick. The interior of the Earth become soft. The heaviest elements sank to the middle and the lightest elements floated on top. This caused the formation of distinct layers in the Earth or‚ in other words‚ differentiate. These distinct layers consist of the core‚ mantle and crust. The inner core is solid iron and nickel because there is too much pressure
