NGSS MS-ESS2-1 Earth’s Systems-Earth Processes
PowerPoint. Earth’s materials are continuously cycling and energy flow drives that process.
All Earth’s processes are the result of energy flowing and matter cycling within and among the planet’s systems. The energy is derived from the sun and the Earth’s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth’s materials and living organisms. Earth materials-a general term that includes minerals, rocks, soil and water.
These are the naturally occurring materials found on Earth that constitute the raw materials upon which our global society exists. Earth materials can be found at the surface and in the interior.
Some examples include minerals, crystals, rock, and metals.
Defines physical change, chemical change, melting, sedimentation, weathering, crystallization, energy, erosion.
The movement of energy that originates from the Earth’s hot interior and causes the cycling of matter through the Earth processes of melting, crystallization, and deformation. Energy flows from the sun cause matter to cycle via the processes that produce weathering, erosion, and sedimentation (e.g. wind, rain). Earth processes vary in time.
Some processes like erosion can take millions of years.
Ex.) Water cutting through rock. The Grand Canyon.
Some processes like earthquakes or tsunamis can cause immediate changes to the Earth. Heat energy drives processes such as melting, crystallization, deformation.
This changes the atomic arrangement of elements in rocks. Internal heat moves and pushes rock material to the Earth’s surface where it is subject to surface processes like weathering and erosion. Given the right setting, any rock on Earth can be changed into a new type of rock by processes driven by the Earth’s internal energy or by energy from the sun.
