In which of these is the chemical weathering rate the slowest?

In which of these is the chemical weathering rate the slowest?

The Antarctic rate arguably represents the slowest chemical weathering rate anywhere on Earth. If we apply the shortest possible residence time (1 Myr) for the stony meteorites at Meridiani and compare at 9% oxidation, the Martian rate approaches the Antarctic rate.

Do cold climates lead to a slower rate of weathering?

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.

What types of climate does weathering happen faster?

CLIMATE: The amount of water in the air and the temperature of an area are both part of an area’s climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.

Why is weathering slow in cold places?

Why is weathering slow in cold dry places? Rate of weathering depends on temperature and moisture. Cold dry places have less water to weather things.

Which is the best example of physical weathering?

The correct answer is (a) the cracking of rock caused by the freezing and thawing of water.

What is the most common type of weathering?

One of the most common types of physical weathering is wedging. Wedging occurs when a substance finds its way into cracks or holes in rock and expands outward.

What leads to a slow rate of weathering?

The correct answer is option ‘high temperature’ as well as ‘low moisture levels’. This is because the high temperature will cause low humidity and if there is low humidity, then there will be less weathering. this is why, high temperature will help in decreasing the rate of weathering or slower the rate of weathering.

What are 4 factors that affect weathering?

Factors affecting weathering

• rock strength/hardness.
• mineral and chemical composition.
• colour.
• rock texture.
• rock structure.

What are the 5 agents of weathering?

Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

What are the 5 factors that affect weathering?

What are 3 examples of physical weathering?

These examples illustrate physical weathering:

• Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom.
• Ice wedging. Ice wedging causes many rocks to break.
• Plant roots. Plant roots can grow in cracks.

What are 5 examples of weathering?

Types of Chemical Weathering

• Carbonation. When you think of carbonation, think carbon!
• Oxidation. Oxygen causes oxidation.
• Hydration. This isn’t the hydration used in your body, but it’s similar.
• Hydrolysis. Water can add to a material to make a new material, or it can dissolve a material to change it.
• Acidification.

How does climate affect the rate of weathering?

Factors that affect the rate of weathering 1. CLIMATE: The amount of water in the air and the temperature of an area are both part of an area’s climate. Moisturespeeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates. Without temperature changes, ice wedging cannot occur.

Which is the most effective form of weathering?

Weathering: the decay of rocks and the source of sediments inand the source of sediments in sedimentary rocks. Geology 200Geology 200 Geology for Environmental Scientists. Physical Weathering. • Ice Wedging (Geo-wedgies!) – the most effective form of ppy ghysical weathering. Ice can exert 1500 lbs/in2.

Why does granite weather more slowly than sedimentary rocks?

Weathering therefore occurs more slowly in granite than in layered sedimentary rocks. 1. Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2.

How does the climate of a rock affect its weather?

Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. 1. Soils affect the rate in which a rock weathers.
