What are the two processes of erosion?
Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) …
What is the difference between erosion and transport?
EROSION: Wearing away the soil and rocks. This puts lots of sand, mud, pebbles and silt into the river. TRANSPORT: Moving material. The force of the flowing water moves the mud, sand, pebbles and silt created by erosion.
When pieces of rock get carried away it is called?
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
What happens when wind sweeps up sand and throws it against a big rock?
What happens when wind sweeps up sand and throws it against a big rock? The sand will act like sandpaper and scrape the rock. If this continues to happen, the surface of the rock will change. Over a long time period the changes to the rock can be dramatic.
What kind of rock is most likely to be damaged by acid rain?
Sulfur dioxide, an acid rain precursor, can react directly with limestone in the presence of water to form gypsum, which eventually flakes off or is dissolved by water. In addition, acid rain can dissolve limestone and marble through direct contact.
Which one of the way can prevent acid rain?
A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
