Wind

Rocks on the surface of Earth are also eroded by the force of ___ which carries sentiments from one place to another

Mixture of mineral particles, air, water and organic material

Soil is a good example of a

Inorganic and organic materials, broken rocks, water, air and minerals

Soil is a mixture of

Surface layer

Soil is the__ of the earth

Soil texture

Soil quality that is based on the portions of soil particles

Transported soil

Soil that is blown or washed away from its parent rock

Residual soil

Soil that remains above its parent rock

Soil fertility

Soils ability to hold nutrients and to supply nutrients to a plant

Sand, silt, Clay or loam

Soils can be classified as_______depending on the size of the particles and the amount of organic material

Crops, animals, timber resources

Soils important for going__grazing__ and for__

Permeability

The ability of soil to let water pass through it quickly

Soil structure

The arrangement of soil particles

Soil

A loose mixture of rock fragments, organic material, water and air that can support growth of vegetation

Soil

A loose mixture of small mineral fragments, organic material, water, and air and I can support the growth of vegetation

Air, water, trees, crops, roads, houses

A soils ability to hold_and_determines its ability to support the growth of_and_and you provide the same ability for_and_

Infiltration

Ability of water to move through the soil

Soil structure

Arrangement of soil particles

Horizans

Because of the way soil forms, soil often ends up in a series of horizontal layers called

Dissolved in the water that penetrates the soil

Before nutrient can be used by a plant it must be

Temperate forests and grasslands

Climate with enough rain to cause a high-level of Chemical weathering, but not so much that the nutrients are leached out of the soil

Tropical rain forest

Climate with heavy rain that lieges precious nutrients from the topsoil

Desert

Climate with less than 25 cm of rain per year and a little ability to support plant and animal life

Arctic areas

Climate with low temperatures and slow soil formation, resulting in thin soil that cannot support many plants

Weak acids

Compounds formed by the burning of fossil fuels combine with water in the atmosphere to form

Weathering and erosion

Earths surface is in a constant state of change because of

The roots can grow enough to be strong to crack a rock

How does a plant break a rock

Mechanical weathering

Ice wind gravity plants and animals can all be agents of

Physical means

Mechanical weathering is a broken down of rock into smaller pieces by

Mechanical weathering

The breakdown of rock into smaller pieces by physical means. Ice, wind, water, gravity, plants and even animals can cause this

Humus

The dark, organic material formed in soil from the decayed remains of plants and animals

Running water

The earths surface is carved and sculpted by

Gravity, wind, water and ice

The four factors that cause weathering and erosion are

Abrasion

The grinding and wearing away of rock services through the mechanical action of other rock and sand particles

Bedrock

The layer of rock beneath the soil

Soil profile

The layering of soil is called a

Ice

The major cause of physical weathering is

Temperate and grassland climates

The most productive soil in the world can be found in which climate

Weathering

The process by which rock materials are broken down by the action of physical and chemical processes

Chemical weathering

The process by which rocks breakdown as a result of chemical reactions. Water, weak acids, and air cause this

Erosion

The process by which wind, water, ice or gravity transports soil and sediment from one location to another

Leaching

The removal of substances that can be dissolved from rock, ore, or layers of soil due to the passing of waters

Parent rock

The rock formation that is the source of mineral fragments in the soil

Soil texture

The soil quality that is based on the proportion of soil particles

Clay, organic, gravel, sand, bedrock

The top layer of soil is__With__material. The middle layer is__and__in the bottom layer is__Fragments

Physical and chemical

The two types of weathering are

Climate

Vegetative Regimes are associates with

Soil

Weathering is an important part of ___ development

Tundra-no large trees but small bushes Forests and woodlands-coniferous, deciduous and evergreen Scrubland-short woody plants and grasses and few small trees Grasslands - grass savannas and prairies Deserts - bare ground with cacti, succulents and trees to conserve water

What are the 5 types of vegetative regimes or biomes

The process by which rock materials are broken down by the action of physical and chemical processes

What is the process of weathering

Burrowing animal and plant roots

What other factors can cause rocks to split

Soil, ecosystems

__ brings nutrients to plants, which forms the basis for all__
