Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.
However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.

tropical depression, according to the NOAA. A well-defined band of storm clouds began to wrap around the north side of the storm's circulation center in the early morning hours of Aug. 24. With winds of about 40 mph (65 kph), the storm was named Tropical Storm Katrina. <span>By the time it made its way to southern Florida on Aug. 25, Katrina was a moderate Category 1 hurricane. While it caused some flooding and casualties — two people were killed — during its first landfall, it appeared to be just another hurricane in an active hurricane season. Katrina weakened after passing over Florida and was reclassified as a tropical storm.</span>
Answer:
• oxygen
• nitrogen
• carbon
Explanation:
Electronegativity is a scale that measures an atom's attraction towards an electron. The more electronegative an atom is, the more it attracts an electron. Electronegativity increases as we go up and from left to right in the periodic table.
Hence, the following elements are considered to have a high level of attraction for surrounding electrons
• oxygen
• nitrogen
• carbon
