Some people could drown in tsunamis other people could get stuck in the waves and crash into hard objects.
I hope that this helps you :-)
There is an interaction between human beings and their surroundings that is known as the human environment. Thus, it can be defined as a means of understanding the way people relate to their natural and physical surroundings. A place's environment is affected by a number of factors, such as its physical, biological, cultural, social, and economic characteristics which are all influenced by a number of factors.

An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.
