characteristics, and more, air and water, the gas and liquid phases, exist in the pores?​

Answer 1

Answer:

Soil moisture is the water stored in the soil and is affected by precipitation, temperature, soil characteristics, and more. These same factors help determine the type of biome present, and the suitability of land for growing crops. The health of our crops relies upon an adequate supply of moisture and soil nutrients, among other things. As moisture availability declines, the normal function and growth of plants are disrupted, and crop yields are reduced. And, as our climate changes, moisture availability is becoming more variable.

Where is the water in soil? Solids, liquids, and gasses, the three phases of matter, are always present in soil. Small mineral and organic particles comprise the solid fraction, and there are spaces (pores) between the solid particles. Some pores are large, and others are very small. Air and water, the gas and liquid phases, exist in the pores. The size of the soil particles and pores affects how much water a soil can hold, and how that water moves through the soil.

Calling all student scientists! Soil scientists and agronomists use gravimetric methods and in-situ instrumentation to monitor soil moisture at the field scale in cropped lands. Other scientists look at a bigger picture, using Earth-observing satellites to survey the planet for soil moisture changes. These data will assist soil scientists, hydrologists, and climatologists in forecasting potential changes in moisture availability. NASA recently launched a satellite called Soil Moisture Active Passive
