Question

What kind of pollution are airborne solids that range in size from large grains to microscopic? A) \(\mathrm{pH}\) C) particulate matter B) ozone D) acid rain

Short answer

C) particulate matter

Step-by-step solution

Understand the Question

The question asks to identify a type of pollution that consists of solid particles present in the air, varying from large visible grains to tiny microscopic particles.

Analyze the Options

Let's examine each option to determine which one fits the description:- A) \(\mathrm{pH}\): Refers to the measure of acidity or alkalinity, not solid particles.- B) Ozone: A gas, not a solid particle.- C) Particulate matter: Tiny particles or droplets in the air that include solid particles.- D) Acid rain: Rain that contains dissolved acidic compounds, not airborne solid particles.

Choose the Correct Option

Based on the analysis, particulate matter is the type of pollution consisting of airborne solids varying from large grains to microscopic entities.

Key concepts

Air Pollution

Air pollution refers to the presence of harmful substances in the air that we breathe. These substances can be in the form of gases, such as ozone or carbon monoxide, or solid particles, known as particulate matter. Air pollution is a significant concern because it affects human health and the environment. It can cause respiratory diseases, heart problems, and even lead to premature death. Additionally, it negatively impacts the natural world by contributing to climate change and damaging ecosystems. Sources of air pollution include industrial emissions, vehicle exhaust, burning of fossil fuels, and natural events like wildfires and volcanic eruptions.

Environmental Science

Environmental science is the study of how natural and human systems interact. It's an interdisciplinary field that encompasses biology, chemistry, physics, geography, and social sciences, aiming to understand and address environmental issues. A major focus of environmental science is studying pollutants and their impact on the environment and public health. Scientists in this field work to develop sustainable solutions to reduce pollution and conserve natural resources. They also analyze data to understand trends in environmental quality and predict future impacts of human activities on the planet. By fostering awareness and understanding, environmental science plays a crucial role in promoting a healthier, more sustainable world.

Atmospheric Particles

Atmospheric particles, often referred to as particulate matter, are tiny solids or liquid droplets found in the air. These particles vary considerably in size, ranging from visible grains like dust and pollen to microscopic particles that can only be seen using a microscope. Particulate matter is categorized by size, typically PM10 and PM2.5, where PM10 includes particles up to 10 micrometers in diameter, and PM2.5 consists of even smaller particles. These particles can originate from different sources, such as construction sites, unpaved roads, smokestacks, and fires. Because of their small size, these particles can penetrate deep into the lungs, causing health problems like asthma, bronchitis, and heart disease. Addressing the sources and effects of atmospheric particles is a key aspect of combating air pollution.
