Which characteristic most determines a rocks resistance to weathering?
The mineral composition of the rock is the most important factor in determining its resistance to weathering. Rocks made up of harder minerals such as quartz or feldspar are generally more resistant to weathering compared to rocks with softer minerals like calcite or gypsum. Additionally, the presence of cementing materials can also affect a rock's weathering resistance.
Which substance has the greatest effect on the rate of weathering of rock?
Water is the substance that has the greatest effect on the rate of weathering of rock. Water can seep into cracks in rock, freeze and expand, causing the rock to break apart. Water can also chemically react with minerals in the rock, leading to chemical weathering.
The variables that most affect the weathering process are rock composition and what?
The variables that most affect the weathering process are rock composition and climate. Rock composition determines the susceptibility of a rock to weathering, while climate influences the rate and type of weathering that occurs, with factors such as temperature, precipitation, and vegetation playing key roles.
Which weathering process tends to form spherical boulders?
Spheroidal weathering is the process that tends to form spherical boulders. This type of weathering occurs on rocks with varying resistance to weathering, resulting in the development of rounded shapes over time due to the uneven weathering of the rock surfaces.
If three rocks have the same mass will the weathering rate be the same?
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.

What are propertys of rock?
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.
What part of a rock does weathering attack most rapidly?
Weathering tends to attack the outermost layer of a rock, known as the rock surface or rind, most rapidly. This layer is more exposed to the elements and is therefore more susceptible to weathering processes such as erosion, chemical weathering, and physical weathering.
What part rocks does weathering attack most rapidly?
Weathering attacks the surface of the rock most rapidly.

Give 2 reasons how weather can cause weathering?
The rain can erode the substanceThe wind becomes very fierce and consquently erodes the substance as well (Wind Erosion)The substance is usually rock, most likely on a statue.
The most of important factors in determining the rate of weathering are what?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
Which weathering process tends to form spherical boulders?
Spheroidal weathering is the process that tends to form spherical boulders. This type of weathering occurs on rocks with varying resistance to weathering, resulting in the development of rounded shapes over time due to the uneven weathering of the rock surfaces.
What is the process that breaks down rock and other substance at earth's surface?
Weathering, which is caused by water, ice, wind and sun.
What are the most important factors in chemical weathering?
Erosion..... As wind, water, and glaciers move rock debris, they relentlessly disintegrate the rock further.
