These crops protect and build soil health by preventing erosion, replenishing soil nutrients, and keeping weeds in check, reducing the need for herbicides.

No-till or reduced till methods, which involve inserting seeds directly into undisturbed soil, can reduce erosion and improve soil health

A growing body of evidence shows that a smart integration of crop and animal production can be a recipe for more efficient, profitable farms.

Sustainable farms treat uncultivated or less intensively cultivated areas, such as riparian buffers or prairie strips, as integral to the farm—valued for their role in controlling erosion, reducing nutrient runoff, and supporting pollinators and other biodiversity.

________________ is the movement of electrons (the tiny particles that makeup atoms, along with protons and neutrons).

________________ is stored in the bonds of atoms and molecules – it is the energy that holds these particles together.

________________ is a form of potential energy that is stored in an elastic object - such as a coiled spring or a stretched elastic band.

________________ is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become.

________________ is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission).

______________ is also known as light energy or electromagnetic energy, it is a type of kinetic energy that travels in waves.

______________ is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up.

______________ is the energy stored in objects; as objects move faster, more energy is stored.

______________ is a form of potential energy. It is an energy associated with gravity or gravitational force – in other words, the energy held by an object when it is in a high position compared to a lower position.

______________ is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate.

_____________ may contaminated drinking water supplies. Contaminated water an make people and animals sick.

_____________ is liquid runoff from dumpsites that seeps into the groundwater. It may have contaminants such as lead.

_____________ it spills in seas and oceans can kill water birds and other water animals.

_____________ rising the temperature can cause a change climate.

_____________ can kills plants and animals on land. It can also kill plants and animals in water. Acid rain can also damage building and statues.

____________ is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.

____________ occurs when harmful substances often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.

____________ degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.

____________ refers to the deterioration of the earth's land surfaces, at and below ground level. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil.

___________is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water.

___________is water located on top of the Earth's surface such as rivers, creeks, and wetlands. This may also be referred to as blue water. The vast majority is produced by precipitation and water runoff from nearby areas.

___________is water from a sea or ocean. On average, the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand.

___________pollution is anything that emits pollution directly into the environment like factories, ships, or farms.

___________is pollution resulting from many diffuse sources, in direct contrast to point source pollution which results from a single source.

____________ refers to biotic and abiotic by products of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests.

____________ , is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases, where their presence is unintended or undesirable.

____________ is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations.

____________ is the permanent removal of trees to make room for something besides forest.

____________ is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
