Earth's Climate System Flashcards
Weather
fluctuating state of the atmosphere
how to describe weather/determine (4)
temperature
windspeed and direction
type of precipitation
type of clouds
climate
Average weather over a certain area or time
how can climate vary?
latitude
distance to large bodies of water
geography
climate system
is an interactive system consisting of the interactions of
the atmosphere, hydrosphere, biosphere, and geosphere.
what are the 4 subsystems?
geosphere
atmosphere
hydrosphere
biosphere
this ss is the most uneven, unstable, and fast-changing part of the climate system
atmosphere
nitrogen and oxygen do not have significant interaction with the sun.
TRUE
trace gases such as water vapor (H2O), carbon
dioxide (CO2), methane (CH4), nitrous oxide (N2O,) and ozone (O3) absorb and emit radiation.
TRUE
What are trace gases also called?
GREENHOUSE GASES
why does ghg increase temperature of earth’s surface?
they absorb the outgoing radiation from the surface and reemit them into the atmosphere.
this is the primary greenhouse gas. why?
WATER VAPOR
most variable component of the atmosphere.
how does the hydrosphere influence the climate system?
storing and transporting large amounts of energy.
(dahil yung oceans kayang makapag-absorb ng sun radiation)
This act as a climate regulator because they strongly influence temperature changes.
OCEANSSSSSSSSS
How can soil and vegetation at the land of geosphere affect climate?
it controls how much energy received from the sun is returned to the environment.
what part/layer of the geosphere affects climate?
crust
Soil moisture greatly affects surface temperature because the evaporation of water from the soil requires energy.
TRUE
What is topography?
description of the surface feature of the land
how does topography affect climate?
affects the wind that blows on the
land surface.
A mountain range may block the path of low
altitude clouds, affecting the weather in surrounding areas.
True
(biosphere) ______ allows the release of oxygen and uptake of carbon dioxide; hence, organisms take part in the exchange of greenhouse gases.
Photosynthesis
Removing large number of plants and trees in an area can cause an increase in free carbon dioxide due to less plant absorbers
TRUE
yes
