D1.1 Flashcards
(15 cards)
Atmosphere
the layer of gases that surround Earth
Biosphere
a relatively thin layer of Earth that has conditions suitable for life
Atmospheric Dust
tiny, solid particles suspended in the atmosphere
Climate
the average weather conditions that occur in a region over a long period of time
Hydrosphere
the water on Earth, whether present as liquid, water vapour, or ice
Inversion
a reversal of normal temperature patterns seen in the troposphere In an inversion, there is an increase of temperature with height through a layer of air
Lithosphere
lithosphere: the solid outer portion of Earth, composed of rocks, minerals, and elements
Mesosphere
the atmospheric layer above the stratosphere, from 50 km to 80 km above Earth’s surface
Ozone
a molecule composed of three atoms of oxygen
Ozone layer
a layer in the stratosphere containing high levels of ozone gas
Ozone gas
absorbs large amounts of energy from the sun rays, which causes the temperature in the stratosphere to increase with altitude - protects living organisms from damaging high energy radiation
stratosphere
the atmospheric layer above the troposphere, from 10 km to 50 km above Earth’s surface
Troposphere
troposphere: the atmospheric layer from 0 km to 10 km above Earth’s surface
Weather
weather: the state of the atmosphere at a particular place and time with regard to temperature, air pressure, cloud cover, precipitation, and humidity
Thermosphere
the highest atmospheric layer, from 80 km to 300 km above Earth’s surface
