Deserts, Glaciers, and Climate

The desert landscape and the glacial landscape have a specific process in the formation of the different geological features. Glacial landscape is known to be made from either glacial deposition or erosion. The area that is under of above the glacial ice forms the erosional features while the ice melts, outwash deposits, met water deposits or tills forms the depositional features. Desert landscapes are usually created through the process that includes volcanic eruptions, erosions, weathering, and tectonic forces. With long periods of climatic cycles dry and wet periods has really contributed to the starting of different dessert landform features which ...view middle of the document...

An example of a desert landscape is Mountains which are made in different ways either erosional, volcanic, fault-block, or folded. Erosional mountains are made when water and wind cause wearing down of weak spots in land causing non-resistant material to wash away while stronger material are left.
(Respond to the following: Summarize the climate changes that have occurred from the past to the present. Predict what you think the Earth will look like into the 21st century. Consider the weather and changes in geological features.)
A specific interpretation of the past and present climate data is and can be difficult. Many theories do explain that the climate changes that have occurred throughout the past years was influenced by the dynamic forces on earth and many other causes like the intensity of the sunlight and the human activities that has caused an increase in green gas emission.
It has been known that the Earth’s climate during the early ages has gone into fluctuation. Many people believe that the Artic area could have been an area with tropical climate with no ice accumulation. The Carbon Dioxide and temperatures from the ice cores and other sources has been found to lead to the speculations. In the last 500,000 years, many ice ages with ice sheets covering big portions of the northern hemisphere has been well known within the planet Earth. This was known as the Ice ages when the certain parts of the Earth were covered by ice. The climate has completely changed during the interglacial periods where ice retreated to the poles or entirely melted.
These changes are linked to the natural causes such as the amount of solar radiation when the sun got brighter with a higher energy level output it passed into the...

Earth has experienced climate change in the past without help from humanity. We know about past climates because of evidence left in tree rings, layers of ice in glaciers, ocean sediments, coral reefs, and layers of sedimentary rocks. For example, bubbles of air in glacial ice trap tiny
