Metamorphic rocks form underground, igneous rocks form as lava cools (usually on the surface) and sedimentary rocks form by lakes and oceans.
I think on the surface.
Answer: Natural Inorganic solid
Explanation: . A mineral is an inorganic solid that possess a crystalline structure and are formed naturally by geological processes. it has a definite composition and an ordered atomic arrangement.
The study of minerals is called mineralogy. A mineral can be made of single chemical element or more usually a compound. Examples such as quartz
Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Explanation:
Answer:
It should be the Prime Meridian.
Explanation:
You do not have a picture but the equator is a line of latitude that travels east to west. The International Date line is an imaginary line through the Pacific Ocean that begins a new day (it has to do with time zones). The Arctic Circle is only in the north and it is a circle, not a line. Lastly, the prime Meridian is a line of longitude that travels from north to south and cuts the world in half between eastern and western hemispheres, like the Equator cuts the globe into the northern and southern hemispheres. The Prime Meridian goes through the Atlantic Ocean and cuts off put of Africa.
