Q

natural greenhouse effect

A

natural warming effect of troposphere. Natural effect that releases heat in atomposhere near earth’s surface. Greenhouse gases (above + ozone) and other gases in lowere atmopshere (troposphere) absor some of infared radiation heat radiated by earths surface. Molecules vibrate and transform absorbed energy into longer wavelenght infared radiation in troposphere. IF atomosphere concentrations of green house gases increase and other natural processes do not remove the, AVG TEMP of lower atmosphere will increase (compare to global warming: warming of earths lower atmosphere (troposphere) b/c increase in concentrations of one or more greenhouse gases. Can result in climate change that last for decades to thousands of years.

Q

soil

A

The top layer of the earth’s surface in which plants can grow, consisting of minerals, dead organic material = abiotic since dead organic. Types of soil clay, sand, and silt. Capable of retaining water

Q

soil’s importance

A

medium for plant growth; principal factor controlling fate water in terrestrial env; nature’s recycling system which breaks down waste products of plants and animals and transforms them into their basic elements; and habitat to diversity of animal life from small mammals to countliess forms microbial life.

Q

what effects does soil show?

A

The unconsolidated mineral or organic matter on the surface of the Earth that has been subjected to and shows effects of genetic and environmental factors of: climate (including water and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time.

Q

what function do each of microcrobes do in soil

A

Soil Fungus good fungi help plants get nutrients from the soil. Mites - soil mites eat good and bad fungus. They carry bacteria around on their backs! They are an important part of healthy soil. Bacteria Bacteria can be good or bad.

Q

Nutrition

A

the energy (food source) needed by living things to be able to survive and thrive

17
Q

Horizon

A

in soil, horizons are another name for its layers

18
Q

Soil is layered.

A

The upper layer or SOIL HORIZON has more organic matter and water, causing it to be darker. Plant roots use this area to get nutrition, water and oxygen.

19
Q

Soil is described by its particle size.

A

All soil is made up of sand, silt and clay. The larger or coarser particles are sand. The smallest particles cling together to make clay. This de- scribes the particle sizes, not the type of parent material it is composed of.

20
Q

soil layers

A

Soil is layered (horizons); the upper A Horizon has more organic matter, water and air. This is good for plants. The lower layers tend to be less broken down, with less organic matter, air and water.

21
Q

Silt

A

a type of soil particle between the smallest (clay) and the largest (sand)

22
Q

soil colors

A

Black/Dark Brown Soil that has high organic matter content and nutrients for plants. Yellow or Gold Soil from certain sandstones. Light Brown Clay soils with low organic matter content. Soils formed mainly in materials left from ancient sea beds. Red Soil with high iron content. White or Cream Soil with high amounts of lime or formed in wind-blown silty material.

23
Q

Parent Materials

A

in soil, parent materials are the types of rocks and minerals that eventually become soil over time

24
Q

How is soil formed?

A

Soil is formed slowly as rocks break down into tiny pieces, through EROSION. Organic material decays (assisted by action living organisms) and mixes with INORGANIC MATERIALS and water to form soil. Soil even has air in it!

25
Q

Soils Make Life | Life Makes Soils

A

Plants grow in and from soils, and plants directly or indirectly feed almost all life on Earth. LIFE to SOIL: Soil-dwellers such as bacteria and fungi recycle once-living organisms into nutrients and soil organic matter (humus) vital components of all soils. Without soils, life would not exist as we know it.

26
Q

Soils Breathe

A

From burrowers to bacteria, the organisms that live in soils respire (breath). Most of them take in oxygen to do their work, and they give off carbon dioxide, just as humans do.Soils breathe because they shelter and support living organisms.

27
Q

Soil or Dirt?

A

Soils are more than dirt. Dirt is a mixture of minerals, air, water, and living and dead things. The possibilities are almost endless bugs, bacteria, fungi, feces, nematodes, worms, roots, rotting plants, ice, minerals

28
Q

Soils have history!

A

Their unique, colorful and exotic layers give us clues to how they have changed over time.

29
Q

loam

A

Loam soil is a mixture of soil that is the ideal plant-growing medium. It is actually a combination soil, normally equal parts of clay, silt, and sand, which gives the benefits of each with few of the disadvantages. By combining these three types of soil, loam gives you the best characteristics of all three. This enables you to grow almost any type of plant without having to add too much to the soil.

30
Q

clay

A

Clay soils are fairly dense, have good water- and nutrient-retaining properties, and are great for growing flowering plants that need a lot of water.

31
Q

silt

A

Silt soils come about halfway between clay and sandy soils so silt soils help clay and sand to mix well. Silt soil is very fine and also holds moisture, but, like clay, it can have a tendency to become compact. Most moisture-loving plants, like colored flowers, vines and grasses, grow well in this smooth and slippery soil.

32
Q

sandy

A

Sandy soils by contrast have a rough texture, which helps give good drainage and allow lots of air in the soil. Sand is ideal for drought-loving plants like cacti; however, because of its drainage properties, nutrients can be washed away. This type of soil can also grow tulips, shrubs and other plants that don’t need too much water. However, unless you just want to grow desert plants, sandy soil isn’t so great by itself.
