The right choices are

porosity

mineral softness

ease of dissolving  

Explanation:

Weathering is a natural phenomenon that breaks down and loosens the surface minerals of rock so they can be transferred away by water, wind and ice from one place to another. Usually weathering depends upon the physical characteristics of rocks. Soft rocks are affected the most because their inter molecular attractions is not so hard and they can be easily broken by water and ice so we can say that solubility also affects the weathering. The porosity is also a factor because more porous means more empty spaces and lose force of attractions.

 

Answer to Q2

The rate of soil formation depends upon

warmer temperatures

very hard parent material

Explanation:

There are five factors responsible for soil development. They are: Climate, organisms, parent material, topography and time. When parent rock material is exposed to the atmosphere or when organic matter is deposited on the earth's surface, soil formation begins. Time. Climate, Temperature and moisture influence the speed of chemical reactions therefore soils develop faster in warm, moist climates and slowest in cold or arid ones.

Answer to Q3

The right choices are

dry climate

cold climate

Explanation:

Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Weathering occurs fastest in hot, wet climates and occurs very slowly in hot and dry climate because without temperature changes, ice wedging cannot occur theretofore in  very cold, dry areas, there is little weathering.

Answer to Q4

Gelisols  is the correct answer

Explanation:

Gelisols came from the Latin word gelare  which means to freeze. They are the soils that are permanently frozen. Gelisols are found in the Arctic and Antarctic, as well as at extremely high elevations. Gelisols are found chiefly in Siberia, Alaska and Canada and all of these areas lie in Arctic. So this is the correct option.

Answer to Q5  

The correct options are

plant growth

pressure release  

Explanation:

Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock. Ice wedging, pressure release, plant root growth, and abrasion are the major causes of mechanical weathering. Repeated heating and cooling of some rock types can cause rocks to stress and break, resulting in weathering and erosion.

Answer to Q6

clay

sand

silt

Explanation:

There are three categories for soil particles which are sand, silt and clay. These three groups are called soil separates. The three groups are divided by their particle size. Clay particles are the smallest, while sand particles are the largest particles found in soil. Slit is granular material of a size between sand and clay.  

Answer to Q7

The correct option is clay

Explanation:

Clay is one of the basic component of soil. Soil contains nutrients that are required for various processes of plant growth. Of all the mineral nutrients, nitrogen contributes the most to plant growth and crop production. Plants require nitrogen to form proteins, nucleic acids, chlorophyll, and other important organic molecules. This nitrogen is provided to plants by clay.

Answer to Q8

It undergoes the most change

Explanation:

Horizon B is also called Subsoil. It is mostly made of clay, iron minerals as well as organic matter, which has been washed down to this horizon by rainwater. This layer usually contain concentrations of clay minerals or of iron or aluminium oxides. Therefore this layer is more exposed to chemical reactions and undergoes most change because it is present between horizon A and horizon C.

Answer to Q9

The correct option is Texture

Explanation:

Texture is something related to shape. By definition texture is the feel, appearance, or consistency of a surface or a substance.The particles of soil have various sizes and shape. Some particles are round shaped and smooth edged while other are rough and tiny. The texture of soil is dependent upon the size of particles p[resent in the that sample of soil.

Answer to Q10  

Correct options are

Bedrock lies below the soil layers,  

Horizon O forms from organic material

Horizon C is least affected by the soil formation process.

Explanation;

Most soil profiles are composed of a series of horizons or layers of soil.

BUT DON'T FORGET what a horizon is- its a surface

horizon - fallen leaves and partially decomposed organic matter

A horizon - A surface mineral horizon, living organisms, and rock particles.

B horizon - A sub-surface horizon where depletion of organic matter and an accumulation of clay.  

C horizon - A layer of partially altered bedrock

The concentration of the reactants decreases.

Explanation: Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

k= rate constant

x = order with respect to

y = order with respect to

Thus as the concentration of reactants decrease, the rate of the reaction also decrease and thus the rate of formation of products decrease.
