Protons - positively charged (+1)
Neutrons - Neutral charge (0)
Electrons - Negatively charged (-1)
Protons and neutrons stay inside the nucleus, while electrons circle the outside.
Answer:
Surface runoff is the flow of water occurring on the ground surface when excess rainwater, storm water, melt-water, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration.
Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment.
Plenty of food and clean water contribute to low death rates. Availability of medicine and social support often coincide with low death rates as well.
The answer is friction. Whenever anything decides to enter our atmosphere, they enter pretty fast, faster than they were in space thanks to gravity. But since they go really fast, they create friction with the gases. Those gases may be flammable and they light up. Then you see that it seems like the meteorite is burning, but actually it's the atmospheric gases around it.
