ecosystems Flashcards
whats all the earths ecosystems and all living things made up of
biosphere
what is hydrosphere
all the water on earth
what is lithosphere
a thick layer of rock surrounding the Earth.
The crust and the Upper mantle
whats the atmosphere
is the gas layer surrounding Earth. It protects life on Earth from harmful radiation and debris from space
how do the 4 spheres link
they all support the living organisms in the biosphere
what is biotic factors
living or once living things
what is abiotic factors
non living things
what are native plants adapted to?
fire
whats is spices diversity
the variety of species on Earth – it includes the number of species and the populations of individuals within each species.
how is humans impacting biodiversity
spreading weeds and other plants, meaning native spices in the area can be damaged or killed.
layers of atmosphere
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
what does troposphere consist of
breathable atmosphere
whats the process of oxygen getting taken up
carbon dioxide released is called cellular respiration
whats the word equation for photosynthesis
carbon dioxide + water + sunlight, chlorophyll = glucose + oxygen
Aerobic respiration equation
glucose + oxygen = carbon dioxide+ water + energy
how have humans disturbed the carbon cycle
deforestation and burning fossil fuels
Over the oceans, evaporation exceeds precipitation, what does this result in
movement of water vapor over the land.
evaporation equations
liquid + gas
condensation equation
gas + liquid
precipitation
occurs when so much water as condensed, the air can no longer hold it.
what is infiltration dependent on
the soil and rocktypes
what is infiltration
its when the water is soaked in by the layer of rock, sand or gravel
what is igneous rock
when hot, molten rock crystallizes and solidifies
what are sedimentary rocks formed from
deposits of smaller rock particles eroded by water or wind
where re metamorphic rocks formed
deep underground where there is high heat and pressure
what does constant compression of soil result in
plants will not survive mainly because there will be less air and water pockets
what does albedo effect refer to?
the fraction of solar energy reflected from earth back to space
if there a black car in a carpark, and it was absorbing the sun would it be low or high albedo?
low albedo
why does the ocean have low albedo
the ocean has low albedo because there are mostly dark colours in the ocean, meaning it absorbs the light instead of reflects
what was the coral reef effected by
the temp increase and carbon dioxide increase
