Measures ocean wind speed, which help predict weather

Measures ocean width, which serves as a guide for ships

Monitor plant life, which help scientists discover new species

Humidity causes water to transpire from plants

Humidity causes air temperature to cool before water can evaporate

Humid air does not have much space left into which water can evaporate

Humid air condenses into precipitation quicker than water can evaporate

Combines into larger and larger droplets until they become so heavy the air can no longer hold them

Pushed down by atmospheric wind currents

Builds up an electric charge opposite that of Earth and is pulled down by its electromagnetic attraction to Earth's surface

Becomes cooler and cooler until it is pushed back down to Earth's surface

because the warm air from the equator moves over oceans not over continents

because cities near the coast receive more direct sunlight than inland cities

because cold air from the poles moves toward inland areas instead of coastal areas

because oceans release heat into the atmosphere when the air is cooler than the water

Deserts tend to contain mountains, which absorb most of the clouds

Deserts have little moisture in the air from which clouds can form

Deserts experience little wind, which blow clouds away

Deserts are so humid, clouds don't form easily

to determine if snow will fall

to determine relative humidity

to determine the altitude of clouds

to determine wind speed and direction

Use SCUBE to take blood samples from marine animals

Use underwater robotics to measure the movements of ocean currents

Telescopes to interpret the sounds made by various marine animals

Use sonar to detect changes in weight of the oceans

Intense sunlight at Earth's poles warms ocean water, creating deep currents that move toward Earth's equator, where the water cools and rises

Intense sunlight at Earth's poles warms ocean water, creating surface currents that move toward Earth's equator, wher ethe water cools and sinks

Intense sunlight at the equator warms ocean water, creating surface currents that move horizontally in circles around the equator

Intense sunlight at the equator warms ocean water, creating surface currents that move toward the Earth's poles, where the water cools and sinks

Severe weather is the ONLY cause of flooding

Rivers experience natural cycles of flooding

Rivers do not flood if man-made obstacles are in place

Flooding always occurs where a river meets the ocean

Natural changes in elevation

Repeatedly speeding up and slowing down of the river

Erodes some areas and deposits sediments onto other areas

Construction of dams causes a river to bend

Source

Mouth

Meander

Tributary

When it bends, sediments get trapped

Sediments are thrown as the river becomes faster

Snow melt scrapes off bits of rock from mountanis

Sediments drop as a river widens and loses velocity (speed)

They are continuously flowing

They are never flowing

They sometimes flow

They flow once, then never again
