I need to know what physical weathering and chemical weathering is for a science project!
Oksana_A [137]
Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller pieces. Various atmospheric aspects are responsible for weathering processes. Weathering is different from erosion. Erosion is the movement of rock pieces and sediment from one area to another. Weathering is the breaking down of rocks and erosion is a wearing away of rocks. There are two main types of weathering: physical (or mechanical) weathering and chemical weathering. Quite often, both forms of weathering will occur together

Physical weathering is also known as mechanical weathering. This type of weathering occurs when rocks and other landforms are broken down by physical factors in the environment. These physical factors include wind, water, sun, ice and temperature changes

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a:________
sweet [91]

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.

  • A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
  • The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
  • The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
  • Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.
