Description: Surface soil particles are held together by various organic substances. The gluing of soil particles together into aggregates helps maintain pores and channels in the soil for air and water to enter and move through it.

Grade Discipline Core Idea
PreK-2 ESS2.A: Earth materials and systems Wind and water change the shape of the land.
3-5 ESS2.A: Earth materials and systems Four major Earth systems interact. Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, organisms, and gravity break rocks, soils, and sediments into smaller pieces and move them around.
6-8 ESS2.A: Earth materials and systems Energy flows and matter cycles within and among Earth's systems, including the sun and Earth's interior as primary energy sources. Plate tectonics is one result of these processes.
9-12 ESS2.A: Earth materials and systems Feedback effects exist within and among Earth's systems.
PreK-2 ESS2.E: Biogeology Plants and animals can change their local environment.
3-5 ESS2.E: Biogeology Living things can affect the physical characteristics of their environment.
6-8 ESS2.E: Biogeology [Content found in LS4.A and LS4.D]
9-12 ESS2.E: Biogeology The biosphere and Earth's other systems have many interconnections that cause a continual co-evolution of Earth's surface and life on it.
PreK-2 ESS3.A: Natural resources Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do.
3-5 ESS3.A: Natural resources Energy and fuels humans use are derived from natural sources and their use affects the environment. Some resources are renewable over time, others are not.
6-8 ESS3.A: Natural resources Humans depend on Earth's land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable. Resources are distributed unevenly around the planet as a result of past geologic processes.
9-12 ESS3.A: Natural resources Resource availability has guided the development of human society and use of natural resources has associated costs, risks, and benefits.
