What is it called when a liquid that is not boiling turns into a vapor?

Evaporation

100

What is fluvial flooding?

River flooding. When a river rises over its bank
100

What is a meteorological drought?

Less rain than usual falls in an area

100

What direction do the trade winds blow?

from east to west

100

This type of precipitation will fall when water vapor deposits directly into a solid crystal and then falls to the ground without melting.

Snow

200
Was the air in the bottle cloudier when you were squeezing it or after you released it?


How does this relate to weather?
It was cloudy after you released it. 


Low pressure = cloudy weather, High pressure= clear weather
200

What were two factors that made the Great Vermont Flood of 1927 so especially damaging compared to other flooding events?

Soil already saturated, trees dormant for autumn, land had been cleared by deforestation, huge amounts of rain (9inches +)

200

Name and define at least 2 types of drought

Meteorological- too little rain

Hydrological- water bodies and aquifers are low

Agricultural- soil is too dry for plant growth

Socioeconomic- human needs affected by lack of water

200

Why does the coast of Peru have such productive fisheries?

Upwelling brings cold, nutrient-rich water toward the surface

200
This type of precipitation is formed in thunderstorms when water gets blown high into the clouds by strong updrafts and grows as it falls and rises repeatedly until it gets big enough that it drops to the ground.
Hail
300

How do clouds stay suspended in the air?

The droplets are tiny so updrafts easily lift them

300

How has urban development disconnected rivers from their floodplains?

It has straightened them out so don't "meander" as much.

300

What is transpiration?

Water vapor given off by plants
300

What affect does El Niño have on the trade winds?

Slows them down (or even reverses them)

300

What is the different between sleet and freezing rain?

Sleet freezes before hitting the ground, freezing rain is liquid until the instant it hits a surface

400

Why does cloud seeding increase precipitation in a given area?

Provides nuclei for freezing of supercooled liquid water in clouds.

400

How can extreme heat from climate change make flooding more dangerous?

Hotter air holds more water. Can alter global wind patterns and make extreme weather more likely

400

How can drought increase the danger of flash flooding?

Dried-out soil becomes compacted, so water flows over it instead of absorbing into it.

400

How would La Niña affect the weather in the Eastern Pacific?

Makes it drier and colder. Higher pressure

400

How is graupel formed?

When supercooled raindrops attach to snowflakes

500

What effect did dropping a lit match have on the cloudiness of the bottle and WHY?

More cloudy because the match added condensation nuclei. Water vapor could not condense without a particle to condense onto.

500

What are two preventative steps that could be taken to lessen the damage from flooding?

Rebuilding floodplains upstream of urban areas, building on higher ground, Don't put electrical boxes and other utilities in the basement

500

Explain how unusually warm winter temperatures can lead to both flooding and drought

Flooding because excessive snow melt causes runoff into rivers and low-lying areas

Drought because that water does not recharge aquifers as well as it would if it melted more gradually.

Make a diagram that shows the Walker Circulation under ENSO Neutral conditions

500

Why makes stellar dendrites a particularly dangerous type of snowflake?

Their unstable arms transform quickly after falling, which can create layers of compacted snow over loose snow. Leads to an avalanche
