The number of fishes and other species decreases in acidic waters.
The optimal pH for most freshwater fishes is between 6.0 and 9.0.
The surface gill causes fishes to die.
These react with oxygen in the air to form sulfuric acid and nitric acid, which falls to the Earth's surface in rain or snow.
It is harmful to aquatic environments.
The warm air rising near the equator forms towers seen, the distribution and abundance of organisms are influenced by the rain that falls in the area.
To understand the patterns of abundance in the rain forests.
Ecologists need to study the global climate as the upper flow life on Earth.
40% less solar energy strikes polar latitudes.
There are tropical forests in a band around the equator.
The air is hot and dry in the north and south.
There is a secondary zone of precipitation at latitudes around 45 to 55 degrees north and south.
The polar regions are dry.
Areas of high pressure are caused by falling air.
Areas of low pressure are caused by rising air.
Sailing ships were able to explore the world because of the westerlies, or so-called northeast/southeast trade winds.
The ITCZ is a part of the tropics.
There is a hot, tropical forest at latitudes of about 30 degrees north and south of the tropics.
The surface flow splits the forests of the Pacific Northwest and Western Europe into two parts, one going toward the pole and the other toward the equator.
The three-cell model provides a good understanding of the global circulation cell, at the poles, but it is oversimplified.
Many high-latitude regions sonality is caused by the tilt of the Earth because the sea has little water left.
The Earth's axis of rotation is desert-like.
The sun is facing directly on the fall equinox.
The constant tilt of the Earth's axis causes changes in the solar energy hitting the Earth.
When a rocket is fired from the North Pole it will fly due south, but its intended target will move and the landing point will be in the west.
Climate is affected by the spring patterns on March 21 and September 22.
All locations in the Northern and Southern have an effect on the autumn equinoxes.
Hemispheres have equal amounts of solar radia.
For half of the year, the Northern Hemisphere tures decrease with elevation.
There is a decrease in air pressure at 60 degrees north.
When air is blown across the northern winter, it expands because of -12degC, whereas in the summer it shrinks because of 16degC.
It cools at a rate of 10degC as it expands.
Tropical temperatures vary for every 1,000 m in elevation, as long as there is no water or cloud.
Southern Hemisphere temperatures also occur.
In addition to seasonal changes in temperatures, the wind produces a temperature change roughly equivalent to that brought direction is diverted by the rotation of the Earth, a phenomenon about by an increase in latitude of 1,000 km.
The charac de Coriolis can be found on mountaintop vegetation even in tropical areas.
Imagine a rocket being fired from the North or South Pole.
Patterns of precipitation can be influenced by the mountains when the rocket reaches the equator.
The target would have moved to the east.
To an observer at the equator, the warm, moist air that the rocket encounters on the windward side of a mountain releases precipitation in the form of rain or snow.
When a rocket is fired from the equator, the western side of theCascade Range is in Washington State.
The east west gives spin to storm systems and is a reason hurricanes spin ern side.
The Southern Hemisphere can be affected by the proximity of a landmass to a large body of water.
As moist air blows across the windward side of a mountain, it rises and cools, and precipitation falls as rain or snow.
Cool air rushes in from the ocean to replace the moist air.
Little precipitation occurs on the leeward side of a mountain.
Water has a very high specific heat, which is markedly from those of their climatic zones.
The amount of energy required to raise the temperature of 1 gram of a frost is never experienced by many.
The heat of the land is lower than in inland areas.
The water allows the land to warm quicker than the water.
If it weren't for the warm water of the sea, the U.S. would be a desert.
The land is cooler at night than the sea.
The major ocean currents act as "pinwheels" and create offshore breezes.
The ocean basins of the fore have a moderating effect on the temperatures of coastal regions in the Northern Hemisphere and counterclockwise in the South.
The warm and cold water are represented by the red and blue arrows.
