Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
The natural flow of rivers can be affected by several factors, such as building dams to provide drinking water, pumping of groundwater, climate change, and building of lands that change how natural water runs into surfaces and into rivers. All of these also disrupt the balance of ecosystem in the area.
Answer:
The correct answer is - C. Pharmacokinetics.
Explanation:
Pharmacokinetics is the branch of pharmacology in which one study of the drugs or medicines are dynamically moved during their intake through the body such as the kinetics of absorption, metabolization, distribution, and excretion.
It is also known as ADME an abbreviation form of absorption, metabolization, distribution, and excretion. In contrast, pharmacodynamics is the study that deals with how it affects the body of an organism.
Ultraviolet, or UV, rays ,these are the rays that can cause sun damage to a person's skin in the form of sunburn. While a person cannot detect the sun's UV rays, he or she can detect the infrared rays via the sensation of heat.
Gamma rays - these are most often found in the core of the sun, during fusion. These rays lose frequency as they move towards the surface.
X-rays -
X-rays are emitted by the sun during solar flares.
Visible light -
visible light are radiation waves that are in the frequency range easily seen by the naked eye. Different wavelengths in the visible light spectrum make up different colors.
Microwaves -
microwave radiation waves emitted by the sun are primarily absorbed by the Earth's atmosphere.
Radio waves -
these waves have the longest wavelengths, and the sun is the brightest source of radio waves.
