MS-ESS2-2 Earth’s Systems-Earth Surface Changes PowerPoint

lMAIN IDEA-Geoscience processes have changed Earth’s surface at varying time and spatial scales. The planet’s systems interact over scales that range from microscopic to global in size. They operate over fractions of seconds to billions of years. These interactions have shaped the past and will determine its future. Water’s movement-both on the land and underground-cause weathering and erosion. Change the land’s surface features and create underground formations. Plate Tectonics-a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle. Their movement and effects at plate boundaries are explained e.g. earthquakes, volcanoes, mountain building, ocean ridges/trenches, subduction (part of the rock cycle). Produce changes on a planetary scale over millions of years. Evidence can explain large scale features of the Earth’s surface and how they change. Subduction-A geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle. Surface Weathering-Weathering causes the disintegration of rock near the surface of the earth. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. Erosion-the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location. Deposition-Material is added to a land form. Earth’s surfaces can change large structures like boulders to small structures like microscopic grains of sand and minerals. Erosion, movement, weathering, and deposition modify surfaces or create new features. Ex.) Mountains and canyons. Some of Earth’s processes take minutes while others take hundreds of millions of years. Catastrophic Event-Large-scale, complex natural events that cause immense damage. Ex.) Earthquakes, volcanoes, meteor impacts. Modify of change features over a very short period of time to other processes. These processes are subject to further changes. A given surface feature is the result of a broad range of geoscience processes occurring at different temporal and spatial scales. Surface features will continue to change in the future as it did in the past.

Can be modified for older or younger learners. Most pictures are animated. Check out my MS-ESS2-2 Earth’s Systems-Earth Surface Changes to check for understanding.
