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.

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.

LS2.A: Interdependent relationships in ecosystems
|
The food of almost any animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants, while decomposers restore some materials back to the soil.

|
Populations of organisms live in a variety of habitats. Change in those habitats affects the organisms living there.

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.

|
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.

|
LS2.A: Interdependent relationships in ecosystems
|
Organisms and populations are dependent on their environmental interactions both with other living things and with nonliving factors, any of which can limit their growth. Competitive, predatory, and mutually beneficial interactions vary across ecosystems but the patterns are shared.

ESS3.A: Natural resources
|
Resource availability has guided the development of human society and use of natural resources has associated costs, risks, and benefits.

LS2.A: Interdependent relationships in ecosystems
|
Ecosystems have carrying capacities resulting from biotic and abiotic factors. The fundamental tension between resource availability and organism populations affects the abundance of species in any given ecosystem.

|
|
Biodiversity is increased by formation of new species and reduced by extinction. Humans depend on biodiversity but also have adverse impacts on it. Sustaining biodiversity is essential to supporting life on Earth. |
