<span>The water cycle is like a big circle and doesn’t really have a starting point. There are 4 main stages involved in water cycle i.e. evaporation, condensation, precipitation and runoff, so, I'd say you become water, you evaporate, then you turn into a cloud and rain, then runoff.</span>
Explanation:
Ions are the species that contain a charge either positive or negative charge.
When a neutral atom loses an electron then it acquires a positive charge. Whereas if a neutral atom gains an electron then it acquires a negative charge.
For example, 
means there is +1 charge on sodium.
But if a compound does not contain any charge then it means the compound is neutral.
For example, in the compound 
there is no charge so, this compound is neutral.
Hence, we can conclude that no ions are present in a sample of .
Answer:
moving bits of rock and soil across the earth’s surface by water, wind, or glaciers
Explanation:
Erosion is the active wearing away of the earth's surface by agents of denudation such as running water, wind, ice and waves.
Denudation is the process of lowering and leveling of the earth surface by gradual breaking and wearing away of the earth.
The sequence of denudation progresses from weathering to erosion through transportation and it finally ends with depositions.
Erosion moves rock bits and soils that have been disintegrated and decayed by the process of weathering. During transportation, eroded materials are carried away to new areas where they are deposited.
Answer:
Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless
ramp is equal to the gravitational potential energy of the block at the top of the ramp. This
value is proportional to the square of the block’s velocity at the bottom of the ramp.
Therefore, the block’s final velocity depends on the height of the ramp but not the steepness
of the ramp
Explanation:
i believe that the answer is the second choice
