The largest canyons and deepest valleys were created by?
by running water and chemical weathering :)
Does chemical weathering occur faster in deserts than in rain forests?
Chemical weathering? No, this happens faster in rain forests. Water is an excellent solvent, and will dissolve a LOT of different materials. The primary form of weathering, however, is physical. Running water will wear away nearly ANY substance, given enough time. The Grand Canyon was created by what is now the Colorado River, wearing away the dirt and rock. You can have physical weathering in the deserts as well; think "sandstorms". Blowing sand can destroy nearly anything.
Is running water chemical or mechanical weathering?
A landslide would be mechanical action, but I don't know if it would be construed as a weathering process. A landslide occurs when enough water percolates through the soil as to actually fill the micro empty pores of the soil structure to actually suspend the soil slightly and make it somewhat buoyant. Water is almost as heavy as soil, so if the water can be retained in the soil long enough the soil becomes buoyant and soil particles are surrounded by a water envelope. With the assistance of gravity the now buoyant particles with very little friction can slide to the point of lowest potential energy, which is generally at the bottom of a grade.
How does running water cause weathering?
it runs over rock/sand/dirt and removes little pieces know as erosion
How did erosion and weathering form a deep canyon?
The running water carries enough weathered material away to form a deep canyon
Which one of the following is a source of chemical weathering a The abrasion of running water b Water freezing in the cracks of exposed rocks?
b. water freezing in the cracks of exposed rocks
Which one of the following is a source of chemical weathering a The abrasion of running water b water freezing in the cracks of exposed rocks c the effects of acid from decaying animals d the growth?
C. The effects of acid from decaying animals

Is a type of weathering caused by chemical reaction with water?
yes, liquid water is a unit of chemical weathering. ice is a unit of physical weathering.
What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
What are some examples of machanical weathering?
3 examples are- 1.ice wedging - when water gets into cracks, freezes and expands 2.roots-while they grow, they push rocks aside that later break. 3.animals- when they dig underground, they push rocks aside causing them to break
. How is physical weathering different from chemical weathering?

What are 5 causes of weathering?
acid rain, wind, tidal, water on surface & chemical
Why is weathering slow in the desert?
Chemical weathering occurs through the processes of solution, hydration, carbonation and oxidation & reduction. Whichever process is followed there is a slight requiremnet of water for the weathering to occur. Because in chemical weathering, minerals in rocks disslove in either water and/or carbonic acid (weak acid, formed when water absorbs carbon dioxide). As a desert has less amount of moisture content, so it is slow in desert.

The grinding action of debris present in running water breaking up bedrock is known as?
abrasion
What are characteristics of mechanical weathering?
Mechanical weathering is when rocks are worn away by physical action, ex: a river running past.
