Geo studying add Flashcards
what is the wind measured with?
the wind is measured with an anemometer.
what is atmosphere
it is the layer of gas that develops a planet
what is the atmosphere measured with
measured with a barometer measured in millibars
what are the 3 layers of the earth
crust, core and mantle
what is sunshine
is the sunlight or direct ray.
what instrument is use to measure precipitation
precipitation is measured with a rain gauge.
how is rain form
it is formed when the sun creates a solar radiation which heats up the land where the warm land heats the air. the air then cools and condenses
what are the 3 types of rain fall
relief, convectional, frontal
what is used to measured clouds
clouds are measured with celiometer
what is the difference between weather and climate
The weather is the temporary day to day change in the atmosphere while climate is the average weather condition that usually changes over 30 years.
what is precipitation?
precipitation is any liquid or frozen water that forms in the atmosphere to fall back on the earth.
what is humidity
humidity is the amount of water in the air
what is temperature
temperature is the measure of how hot or cold something is.
what is temperature measured with
temperature is measured with a thermometer
elements of weather
wind, (precipitation: rain, snow, hail, sleet.), air pressure, clouds,sunshine
what is humidity measured with
its is measured with a hygrometer
how are clouds formed?
clouds are formed when invisable water vapour in the air turns into visable water droplets of ice crystals.
examples of air pressure
sinlcing air, cool air, blue sky
what is wind
wind is the movement of air caused by the uneven heating of the earth’s own rotation and sun.
characteristics of the crust
It’s the thinnest layer, the outer layer is called the atmosphere, between 20km-70km
what are cumulonmibus clouds
they are the clouds with lighting, thunder, and thunder storms
what is plate tectonic
plate tectonic is the study of tectonic plates the various movements and features form as movement
what happens a divergent plate
at a divergent plate boundry crustal plate are moving away from each other. which creates a small place where magma cools and rises
what does divergent plate boundary form
divergent plate boundary forms a new crust.
when magma forms it can causes earth quakes and volcanoes
what happen at a collision zone
at a collision zone 2 contiental plate a colliding, they dont sink so the rocks are folded upwards to form fold mountain
examples of collision zone
aegean and turkish, arabian and irain plate
what are the differences between continental and oceanic crust
continental carries contients while oceanic carries ocean, continental is less denser, oceanic is denser
what happens at a convergent plate boundary
at a convergent plate boundary oceanic and continantal plates are colliding. The oceanic plate is more denser so it sinks into the mantle which breaks and melts creating a subduction zone.
what happen at a subduction zone
at a subduction zone deep sea trenches, volient earthquakes occur. (vocanoes)
what plate boundary has, vocanoes, earth quakes and fold mountains
convergent plate boundary
what happens when contiental crust override the oceanic crust
It forms fold mountains
Examples of fold mountains
ande and himalaya mount range
what happens at a transform plate boundary
plates are sliding past each other in the same direction or in oppisite.
NO crust is formed or destroyed.
examples of transform plate boundary
north american & caribbean plate, north and south plate boundary.
what is absolute location
its the exact or accurate location of a place.
what does absolute location uses
used longitude and latitude
what is relative location
It gives location relative to another
an example of relative location
the building is north of the pond
what types of rainfall occurs in the caribbean
covectional rainfall
what is humidity measured in
in percentage
what is the difference between small & large temperature range
small temperature ranges do not change a lot while large temperature range change a lot.
what is diurnal temperature range
difference between temperature in a day
what is latitude
the distance north or south the equator
what is longitude
the distance of a place east or west of the meridian
what is weathering
the wearing away of rocks caused/\ by the weather in the atmosphere
what is soil creep
slow down slope movement of debris on top of slopes 2 to 5 degrees under the influenze of gravity
what is land slides
a sudden/ rapid down slope movement of large volume of soil and rocks
what are things that cause soil creeps
the alternate of wetting and drying of the soil, the alternate of freezing and throwing of the soil
physical causes of landslides
heavy rain as water acts as a lubricant, volcanoes, cause vibration which can cause soil and rock to move
the weathering processes
chemical
what is mass movement
It’s the down slope movement of debris (rocks, soil) under the influence of gravity.
what is erosion
the process in which materials are worn away and transported by wind or water
what is denudaction
the wearing land caused by weathering and erosion, Includes rain, wind temperature range
what is another word for mass movement
mass wasting
The effects of soil creep
electricity pole, fence broken, terracettes
the difference between weathering and erosion
in weathering no movement is involved in situ while with erosion movement occures the agents move the rocks
