The depth of a soil profile is dependent on the type of parent material. the more easily weathered the parent material, the deeper the soil profile. select one: True.
“Soil profile is defined as the vertical section of the soil from the ground surface downwards to where the soil meets the underlying rock.”
- The soil is the topmost layer of the earth’s crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons.
- Soil profile helps in determining the role of the soil as well. It helps one to differentiate the given sample of soil from other soil samples based on factors like its colour, texture, structure, and thickness, as well as its chemical composition.
- here The parent material of a soil determines the original supply of those nutrient elements that are released by physical and chemical weathering and influences the balance between nutrient loss and retention. Organic acids and exudates produced by microorganisms and plants enhance the weathering of minerals and the release of nutrients.

Answer:
Sea floor spreading theory is given Harry Hess the line of evidence that support this are given as under.
Explanation:
Evidence from Molten Matter
In the 1960s scientists found that there is a presence of new materials from below that need the lava to be uplifted and spread along the boundaries of mid-oceanic ridges i.e the lava or magma spreads through the active plate margins of both plates. The red sea is newly formed is an example of spreading, <u>(a process of oceanic basin creation)</u>.
Evidence from Magnetic strips
The magnetism of the earth helped the scientists study the process of seafloor spreading as the newly formed lava gets deposited on either side of the ridges it takes the magnetic properties of the earth. The ocean floor is divided into strips of north and south after cooling.
Active and passive plate margins.
The tri-junction of plates and newly discovered plate like that od red sea and splitting of the rift valley and transform faults. Movement of continents away from each other. Examples include Eastern pacific rise and Mid Atlantic ridge.
Answer:
1.bd=~ed given
2.CD=~fd given
3.<bdc=<edf
4.triangle BCD=~triangle def by s.s.a.axiom
5.BC=~ef the corresponding side of congruent triangle are equal
Explanation:
in triangle qrs &rst
- rs=~rs common side
- qr=~st midpoint bisect that side
- <qsr=<rst midpoint bisect that angle
4.traingle qrs =~rst by s.s.a.axiom
5.<rqs=<rts since the corresponding angle of congruent triangle are equal
Answer:
because the sun heats the Earth more at the equator than at the poles.
