Lesson 1 History Of Glaciation | PPT

Lesson 1 History Of Glaciation | PPT The document discusses the history of glaciation. it explains that ice ages were first discovered in the 1830s and that ice cores have provided evidence of past climate changes over the last 800,000 years. Explore the history of glaciation, from ice ages to glacier formation and erosion processes, with stunning artwork by lawren harris and arthur lismer. discover the impact of glaciers on landscapes and the environment through informative visuals and explanations.

Lesson 1 History Of Glaciation | PPT 1 glaciation 2 introduction the ice age was known as the pleistocene. during this time, there were periods of ice advance glacials and periods of ice retreat interglacials. the glacier system a glacier behaves like a system with inputs, stores, flows and outputs. glacial activity is a balance between the accumulation of snow and ablation or loss by. Why are they important? < 10% of continental area, but occurred at various times over the earth’s history at 3/4 of continental surface (last major iceage: pleistocene (1.6 0.01 ma)); store ~75% of the fresh water on earth; glacier meltwater: major source for summer stream flow for many regions. In a short time the snowflakes settle by compaction under their own weight and much of the air between them is driven out. this eventually forms glacier ice. 2) ice core records from greenland and antarctica provide evidence of climate cycles over the past 800,000 years through analyzing trapped air bubbles and co2 concentrations.

Objectives summarize the evidence that is used to deduce the existence and causes of ancient ice ages. list other instances of glaciation from across our solar system. Learn about glaciers and glaciation, including their formation, different types, and how they move. explore the theory of glacial ages and the distribution of glaciers. Major ice ages contain many glacial advances we are still in the pliocene quaternary major ice age from formation of panama and himalayan mountains 2.58 m bp. all the major ice ages contain many glacial advances called glaciations and glacial retreats called interglaciations. It explains the factors influencing glaciation, including milankovitch cycles, and distinguishes between alpine and continental glaciers. key concepts include glacial movement, transportation, and deposition features such as moraines. download as a pptx, pdf or view online for free.
