X-rays are fast and and simple method of imaging recommended by most of the doctors nowadays, it is painless and doesn't require much preparation and also doesn't require recovery time after having x-rays.

accumulation
plucking
grinding

Answers

The correct answer is accumulation.

The way a glacier moves determines on the relationship which is between the accumulation and wastage.

Glacier is termed as a persistent body dense ice which is constantly moving under its own weight.

It is formed where accumulation of snow exceeds its ablation or sublimation and melting.

Glacier flow and deform because of stressed and also distinguish features.

99% of glacier on earth is contained in the vast ice sheets in polar regions. Glacier can be found on mountain ranges.

Accumulation
The movement of a glacier depends on the ablation, or wastage, and the accumulation.

Which of the following is the best example of a way human lifestyles affect environmental systems?Burning fossil fuels increases the amount of greenhouse gases in the atmosphere.
Using radioactive materials causes ground pollution when chlorofluorocarbons (CFCs) seep into the ground.
Deforestation causes water pollution by decreasing water vapor in nearby lakes and rivers.
Using aerosol sprays increases the amount of ozone (O3) in the atmosphere.

Answers

The first one is the best example because fossil fuels are very scarce on earth and cannot be replaced burning them increases greenhouse gasses such as (carbon dioxide - CO2, water vapor and methane) when these are released into the environment they lead to global warming. One is the answer because it is directly caused by humans and how they live and directly affects the environment.

The best example of a way human lifestyles affect environmental systems is that burning fossil fuels increases the amount of greenhousegases in the atmosphere.

WHAT IS POLLUTION

Pollution is the release of toxic or harmful substances into the environment. These toxic substances can either be released into the air, water or land.

Anthropogenic activities i.e. human activities can be a source of pollution to the environment.

Fossil fuels include petrol, kerosene etc. and when burnt via the use of automobiles can release greenhouse gases like CO2, SO2 into the atmosphere causing global warming.

Therefore, the best example of a way human lifestyles affect environmental systems is that burningfossil fuels increases the amount of greenhouse gases in the atmosphere.
