Refugees migrate primarily because of push factors associated with violence or major disasters such as famine or earthquakes in their home countries. These are the major factors that push refugees to migrate to other countries, however, there are other factors that push migrants more generally to other places such as the lack of work or economic turmoil in their home countries.
Answer:
The true statement is:
d. It is impossible to know which contains more energy.
Explanation:
In this scenario, the frequencies of Photon A and Photon B were not given. This makes it impossible to know which photon contains more energy than the other. Note that the amount of energy is directly proportional to the photon's electromagnetic frequency but inversely proportional to the wavelength. A description of the associated wavelengths was offered, but this description is not enough to help determine the energy of each photon. In conclusion, the photon's frequency determines its energy level just as the wavelength reduces its energy.
The correct answer is A. Rocks are broken into smaller pieces.
Explanation:
In geography, the term weathering is used to refer to the process in which rocks and others such as soil or mineral break into smaller pieces. This can occur due to chemical agents or due to physical factors. Physical weathering includes factors such as temperature, physical contact or pressure that make rocks and other materials break in smaller pieces without changing the general properties or composition of the material. Additionally, these pieces along with other materials form the soil. According to this, the change that takes place during physical weathering is "Rocks are broken into smaller pieces".
