The geographically informed person must know that physical solution create, maintain, and also modify the attributes that constitute earth’s surface. The physical environment provides the essential background for every human task on Earth.

You are watching: The geological processes that shape earth’s features today

Therefore, standard 7 has these themes: contents of earth’s Physical Systems, Earth-Sun Relationships, and also Physical Processes.

There are 4 physical systems: the atmosphere, the biosphere, the hydrosphere, and the lithosphere. These constitute the crucial units of the planet’s physics systems. Recognizing the interactions within and among these four components offers insights top top how earth serves together the home of every living things—plants, animals, and humans.

Almost every one of Earth’s energy originates from the Sun. The synchronized Earth-Sun relationships are vital for the planet to be habitable and capable of supporting life as we understand it. Earth’s place relative to the sunlight affects events and also conditions in every part of the world. The quantity of solar power a location receives counts on the cyclically transforming angles that the Sun’s rays. The seasons an outcome from the tilt that Earth and also its revolution around the Sun causing variable heating patterns, and thus significantly influences climate and also weather and also human activity.

The physical procedures on earth create constant change. This processes—including motion in the tectonic key in the crust, wind and also water erosion, and deposition—shape attributes on earth surface.

Understanding how physical systems work can influence the options people make around where lock live, the varieties of buildings they construct, the travel networks lock develop, and how they normally conduct their lives. Offered the unsure trajectory and also effects of global climate change, knowledge around the components that impact weather and also climate is essential for both an individual and government decision-making. Global climate change is a windy policy concern that should be handle by governments, causing actions that recognize the health, safety, and also economic health of people across the world. Reasoned and also responsible politics decisions need to derive from a clear expertise of the interactions amongst Earth’s physics systems, and also the processes developing them.

1. The four materials of earth’s physical solution (the atmosphere, biosphere, hydrosphere, and lithosphere) are interdependent

Therefore, the student is may be to:

A. Identify and also describe fads in the environment that result from the communication of earth’s physical processes, as exemplified by being able to

Identify and describe the connections in between ocean circulation system and also climate (e.g., phibìc Atlantic Drift and also the soft climate of west Europe, the climatic effects of El Niño or La Niña).Identify and describe the patterns that an outcome from the connections in between climate and also vegetation (e.g., instances of trends of ecosys­tems and also biomes).Identify and also describe the trends of physical functions that result from erosion and also deposition (e.g., estuaries and deltas, canyons, al­luvial plains, sand dunes).

B. Analyze and explain patterns of physical functions resulting native the interaction of earth physical processes, together exemplified by being able to

Analyze maps of tectonic plates come predict the ar of physical features (e.g., hill ranges, volcanoes, rift valleys).Analyze the pattern of glacial attributes as a result of glacial retreat (e.g., moraines, kettle lakes, cirques).Analyze and also explain components influencing precipitation patterns and predict where the fads will occur (e.g., convectional, orographic, frontal). Earth-Sun relationships

2. Earth-Sun relationship drives physical procedures that monitor an annual cycle and also create patterns on Earth

Therefore, the college student is maybe to:

A. Define how Earth-Sun relationships drive earth’s physical processes and create yearly patterns, as exemplified by being able to

Explain the events of weather phenomena in different loca­tions early to yearly changes in the Earth-Sun connection (e.g., hur­ricanes in the loss in subtropical areas, monsoon rainfall, tornadoes in the mid-latitudes during the spring and summer).Explain why the hrs of visible sunlight changes with periods (e.g., the equatorial region experiences approximately 12 hours of sunlight year ring while places in the Arctic and Antarctic circles differ from 0 to 24 hours of visible sunlight).Describe just how the edge of the Sun’s rays alters at different lati­tudes by glowing a light straight on the equator that a globe and also noting the change in the ar (on the tropic lines) and also angle of the direct rays as the tilted globe is moved to represent the different seasons.
