Erosion can benefit the environment.
Erosion is caused by human activities.
Erosion is caused by the wind, water, and gravity.
Erosion occurs when chemical activities break down rock.
The process of erosion creates soil.
The process of erosion moves soil.
The correct answers are:
- Erosion can be harmful to the environment; bigger erosion in a shorter time span can be very destructive to the environment because whole layers of soil will be moved away and the landscape and the features of the environment will be changed.
- Erosion is caused by human activities; people have a big impact on the erosion, mainly by destroying the vegetation which is essential for prevention of this process.
- Erosion is caused by the wind, water, and gravity; these three are the natural factors that are causing the erosion, and that manage to move the soil away from a particular place.
- The process of erosion moves soil; the process of erosion in its essence means exactly that, moving of soil, and while this is bad for the place from where the soil is moved away, it can be good for the place where the material will be deposited later on.
Answer
- Erosion can be harmful to the environment
- Erosion is caused by human activities
- Erosion is caused by the wind, water, and gravity
- The process of erosion moves soil

After two half-lives, there is no longer any of the original radioactive material remaining. Thus, the given statement is true.
A radioactive isotope's half-life is the amount of time it takes for the number of nuclei in a sample to decrease by half. The Phanerozoic eon refers to the whole period of geologic time that preceded the start of the Paleozoic era. The isotope's mass number is unaffected by the emission of a beta particle. There is no longer any of the original radioactive material after two half-lives.
A half-life, or the amount of time it takes for half of a substance to decay radioactively, is what distinguishes natural radioactive processes. It is simple to determine how much material remains after a specific number of half-lives. For instance, the six-hour half-life of the aforementioned technetium-99m indicates that starting at 100 percent, after six hours, we can no longer detect it.
