Layers
What is the layer of the atmosphere closest to Earth's surface where all weather occurs?
What is the troposphere?
What type of radiation from the Sun is visible and consists of a mixture of colors seen in a rainbow?
What is visible light?
What is the movement of air from areas of high pressure to areas of low pressure called?
What is wind?
What is the contamination of air by harmful substances, including gases and smoke, known as?
What is air pollution?
What gas makes up approximately 78% of Earth’s atmosphere and is essential for life?
What is nitrogen?
Which atmospheric layer, extending up to about 50 km, contains the ozone layer that protects Earth from UV rays?
What is the stratosphere?
This form of energy has wavelengths longer than visible light and can be felt as heat but is not visible. What is it called?
What is infrared radiation (IR)?
What type of winds blow over short distances and are created by unequal heating, such as land and sea breezes?
What are local winds?
What type of pollution comes from an identifiable source, such as smokestacks or volcanic eruptions?
What is point-source pollution?
What gas constitutes about 21% of the atmosphere and is vital for respiration in most living organisms?
What is oxygen?
In which layer of the atmosphere, spanning from 50 km to 80 km, do most meteoroids burn up upon entering?
What is the mesosphere?
What type of sunlight has short wavelengths and can break chemical bonds, posing potential harm to living organisms?
What is ultraviolet light (UV)?
What are the steady winds that flow from east to west between 30°N and 30°S latitude called?
What are trade winds?
This type of pollution comes from widespread areas and cannot be traced back to a single source. What is it called?
What is nonpoint-source pollution?
This invisible gas, present in small amounts, plays a critical role in the greenhouse effect and is vital for photosynthesis. What is it?
What is carbon dioxide?
What is the name of the thermosphere's lower layer that contains ions and allows for radio wave reflection?
What is the ionosphere?
What is the term for the transfer of thermal energy through contact between particles of matter, occurring at the atmosphere's contact with Earth?
What is conduction?
What term describes the temperature at which air becomes fully saturated with water vapor due to decreasing temperatures?
What is the dew point?
What term describes precipitation with a pH lower than normal rainwater, formed by sulfur dioxide and nitrogen oxides combining with moisture?
What is acid precipitation?
Question: What term refers to water in its gaseous form, which is an essential component of the atmosphere and contributes to weather patterns?
What is water vapor?
Which is the outermost layer of the atmosphere, extending beyond 500 km, where satellites orbit?
What is the exosphere?
What phenomenon is formed when less dense, warmed air rises while cooler, denser air moves downward, creating air circulation?
What are convection currents?
What is the term for water in liquid or solid form that falls from the atmosphere, including types like rain and snow?
What is precipitation?
What is the index used to report daily air quality, alerting people with allergies or respiratory issues when conditions are dangerous?
What is the Air Quality Index (AQI)?
What is formed when lightning interacts with oxygen in the air, resulting in a molecule consisting of three oxygen atoms?
What is ozone?
