What are watersheds??
an area of water in which all inland waters drain into the same larger body
How are the limits/boarders of watersheds determined??
Natural boundaries formed by virtual lines across the crest of nearby mountains,Hills, or other high ground
What are watersheds divides called??
Watersheds divides or watersheds
What are factors that can affect how water flows in a watershed??
-topography; the shape/slope and terrain of the area
-geology; the type depth and structure of the rock
-climate; rain or snowfall, winds, and temperature
-vegetation; density and diversity
-agricultural; industrial and Urban development
what are air masses??
- they are large expanses of the atmosphere with relatively uniform temperature and humidity
what is an anti-cyclone??
an area of atmospheric circulation surrounding a high-pressure center. THe air turns clockwise in the northern hemisphere and counterclockwise in the southern hemisphere
what is cyclone??
is an are of atmospheric circulation surrounding a high-pressure center. The air turns counterclockwise in the Northern hemisphere and clockwise in the South-hemisphere
How is an anti-cyclone formed??
when air cools, its particles do not collide as frequently, and the pressure tends to fall. To compensate, the particles move closer together, air dentistry increases . The Air Mass this becomes heavier and sinks towards the ground, compressing the particles beneath it and creating an area of high pressure
What is the symbol for an anti-cyclone??
H
How does a cyclone form??
-when air warms, its density decreased. There air mass becomes lighter and rises, leaving an empty space beneath it. The space becomes an area of low pressure.
What is the symbol for cyclone??
L
What kind of weather is associated with a anti-cyclone??
The sky is clear, and the weather stable; dry amd sunny in the commer and cold in the winter
What kind of weather is associated with anti-cyclone
-encourages clouds, with results in precipitation
How does the moon exert gravitational force around the bodies around
-Since the earth sound like stop, the side facing the moon changes throughout the day. The water masses on the side closest to the moon are then attracted to it. As a result they swell, forming a slight bulge in the moon direction
What happens at the same time as the moon exerts gravitational force??
The waters on the opposite sides of the Earth also swell. The water here are less attracted to the Moon than the Earth itself is, so the Earth is drawn away from them, towards the moon
what are fossil fuels??
result from the transformation of organic residue . These energy sources consist of oil, natural gas and coal
how are fossil fuels made?? (oil)
from small Marine animals and algae that lived in the seas a very long ago. When they did, these organisms ask to the bottom of the ocean. Where they were gradually covers, in sand, salts, and other rocks and minerals UNder pressure from the layers of sediment above them, they very slowly turned into oil.
How are fossil fuels made?? (Coal)??
coal for snot come from marine organisms but from terrestrial plants and trees that once grew in swamps. Overtime these snaps were buried under sand and silt. The organic residue was compressed, and it turned into coal. Unlike oil this is a liquid
What is uranium??
a radioactive element that occurs naturally in the Earths crust
What is nuclear energy??
the energy stored in the bonds between the particles in the nucleus of an atom?
What are advantages of nuclear energy?
- it can produce a lot of Mercy from a small amount of supply
-if doesn’t emit any greenhouse gasses
WHat are disadvantages of nuclear energy??
- it accompanied by radioactivity
-it produces a lot of waste, unused things
-non-renewable
-high cost of production
What is Geothermal energy??
the energy that comes from the internal heat of the Earth
How is geothermal energy created?
a fluid is circulated deep. it is heated by the molten rock and rises to the surface. It is now charged with energy
