A student reads that soil is formed in part due to the weathering of rocks. The student lists methods in which rocks break down in a chart, as shown. Weathering of Rocks
1. Acid rain dissolves rock elements
2. Temperature fluctuations cause cracks and fissures in rocks
3. Animals break apart rocks when forming underground burrows.
4. Plant roots apply pressure on rocks
which are accurate methods of the weathering of rocks?

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
