Weathering/erosion/soil
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__
