Why are the grains of sand on a beach so small?
Well, sand starts as pebbles and rocks. These rock then grind against each other breaking smaller & smaller until you get sand.
What type of friction occurs when 2 solids rub against each other?
Sliding friction occurs when two solids rub against each other.
What is produced when two objects slide against each other?
Friction is produced when two objects slide against each other, heat is also another product.
What force decreases the acceleration of two objects moving against each other?
The force that decreases the acceleration of two objects moving against each other is the gravitational force.
What do particles constantly do with each other and the walls of their containers?
bounce and rebound against each other with a velocity dependent on the temperature.
What is it called when rocks grind against each other?
It is called Abrasion.
What is the term for the wearing away of rock by a grinding action?
The action of rocks grinding against each other and wearing away exposed surfaces is abrasion. Differential weathering is a process by which softer, less weather-resistant rocks are worn away, leaving more weather-resistant rocks exposed.
What polishes rocks?
People purchase rock tumblers to polish rocks. These machines range drastically in price and spin the rocks against each other in a machine to make them shine.
Rocks are ground to sand a chemical change?
Usually not, it is mostly the mechanical action of rocks rubbing against each other.
What are three agents that can cause abrasion?
water, air, and gravity (rocks scrape against each other by the cause of gravity.)
Is it erosion when glaciers scrape rocks as the glacier moves across the earth's surface?
Yes, because when rocks or ice that are natural rub against each other is called erosion
What are some ways in which abraision of rocks can happen?
The abraision of rocks can happen when one rock hits another, when river rocks tumble in the riverbed by fast moving water, by blowing sand particles hitting the rock, and when rocks grind against each other.
What is most likely to happen along a transform fault boundary?
At these boundaries, the rocks grind and slide against each other, causing earthquakes.
What grinds rock away by other rock particles?
Water, Wind or Glacier could make rocks hit and grind each other. This process is termed Attrition.
How is beach sand moved on the shoreline?
Erosion or the process of Rocks rubbing each other by the wind or water then they form tiny bits of rock. The process take tousands and thousands of years.
Candidates of opposing parties run against each other for particular office?
The question describes the election process.
What is the process of abrasion?
Abrasion occurs then rocks and stones, picked up by the glacier through plucking, are rubbed against the bedrock at the bottom and side of the glacier, as the glacier passes, pulled down hill by gravity. This causes wearing on the landscape.
