mind is what is a relief? A relief is a land form that is naturally developed or created on the earth’s surface‚ and the study of these land forms is called topography as such the term topographic relief is just land forms that are studied. These landforms are able to be studied through theories that were originated by pioneers such as Alfred Wegener‚ Harry Hess‚ J. Tuzo Wilson and many others‚ theses men all contributed to plate tectonics; which is the study of the plates that makeup the lithosphere

Sediments are often deposited in a series of layers that can differ in thickness and character and also consist of features‚ such as ripple marks.

Chapter One The theory of plate tectonics explains how forces within the planet create landforms. This theory views Earth’s crust as divided into more than a dozen‚ rigid‚ slow-moving plates. Some plates are as large as a quarter of the planet‚ but others are only a few hundred miles across. The plates slowly move across the upper mantle‚ usually less than an inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a few

Volcanic mountains are mountains that form when molten rock erupts onto the earth’s surface. They can either form on land or in the ocean. The Cascade Range in Washington‚ Oregon and northern California is composed of volcanic mountains. Some of the largest volcanic mountains are found along divergent boundaries‚ which form the mid-ocean ridges. The mid-ocean ridges have huge volcanic mountain chains that run through the Atlantic‚ Pacific and Indian Oceans. The mountains in the mid-ocean ridges can

These causes have negative effect on the natural environment which leads to increasing of temperature‚ increasing in sea level‚ changing of precipitations‚ extremely weather‚ killing species of animals‚ birds‚ fish and plants. This essay will show that the causes of climate change have different effects on the environment. Atmospheric carbon dioxide variations‚ volcanic eruptions and solar outputs‚ have negative

It is one of the active volcanoes in the Philippines. Biliran volcano comprises the whole 20x35 km Island of Biliran which is formed by a group of lava domes. It is located across the narrow Biliran Strait from the northern tip of Leyte Island. Biliran volcano is at the northern end of a 170 km long volcanic chain extending SSE to Panaon

earth’s crust that allows hot magma‚ volcanic ashes and gases to escape from below the earth’s surface. This usually happens where the tectonic plates are diverging or converging‚ but can also appear where the earth’s crust is thin and stretched. Tectonic plates are the large scale motion of earth’s lithosphere. An eruption happens when thick magma and large amounts of gas build up under the surface. During a volcanic eruption‚ lava‚ tephra (ash‚ lapilli‚ volcanic bombs and blocks)‚ and various gases

Discuss volcanic hazards. Although commonly thought to be associated with most volcanic eruptions (by the general public)‚ lava is rarely responsible for the loss of life. Which hazards would tend to be more deadly? Finally‚ indicate and discuss those hazards that are a direct result of a volcanic eruption as well as those hazards that are indirectly linked. (Hint: think of indirectly associated” hazards as “side effects.”) Some of volcanic hazards include gases‚ lava and pyroclastic
