whats the difference between leeward and windward sides of a mountain?

Leeward is away from the wind; windward is on the side of the wind. with regard to mountains, the leeward side is the one without rainfall, while the windward side receives lots more rainfall. The death valley is surrounded by mountains and is on the leeward side of all these mountains. Hence it is so dry.

Horizontal is sideways. Think of the horizon. It goes sideways (not up and down) across the sky.

obviously you are referring to ocean weather conditions.  from surfing i know that off shore winds mean the wind is blowing towards the ocean (pacific side would be west) and onshore means the wind is blowing off the ocean towards the beach (pacific side would be east)  off shore makes for the best surf, incaser you were wondering.

Types of Winds\n\n Trade Winds:  In both hemispheres, the winds that blow from 30 degrees latitude from the equator are called trade winds.  The Coriolis effect causes the trade winds to curve. \n\n The Doldrums and Horse Latitudes: Trade winds of Northern and  Southern Hemispheres meet in an area of low pressure around  the equator  called the doldrums.  Sinking air crates an area of high area called horse latitudes. Here the winds are weak.\n\n Westerlies:  Wind belts found in both the Northern and Southern Hemispheres between 30 degrees and 60 degrees latitude. They flow toward the poles in opposite direction of the trade winds.\n\n Polar Easterlies: Wind belts that extend from the poles to 60 degrees latitude in both hemispheres. They are formed from sinking, cold air moving from the poles toward 60 degrees north and 60 degrees south latitude.\n\n Jet  Streams: Narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere.\n\n Local Winds: An area's geography for example a mountain or a shoreline sometimes produces temperature differences that cause local winds like land and sea breezes.

yes.  a river will flow from higher terrain to lower terrain, independent of the compass direction.  two rivers near where i live that flow north are the Red River of the north (North Dakota/ Minnesota border) and the Nemadji River (northwest Wisconsin).

They come from the east. Meteorologists refer to the wind by the direction in which the winds are coming.

"Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect)."

wind. the speed of the current traveling through the lines. when they pass each other they make contact.

"Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface."\n\nThe sun heats up the earth's surface, the hot air rises while the cool air sinks, therefore create air movement - which is called wind.

razor may be thinking of a Darrieus machine which does have a vertical spin axis. But a downwind turbine has a normal fan-type rotor whose blades are on the lee side of the support mast (ref.). If built without excessive nacelle area on the windward side, this just naturally yaws in the proper direction due to the wind force on the rotor driving it leeward. Another advantage is that the rotor can be more flexible because collision with the mast is normally not possible. However as the ref. points out, there are also disadvantages to this design, including cyclic blade loads due to the support's wind shadow.

It is downhill from start to mouth using sea level. However, there are rivers that do flow uphill at times. The continental divide is the reason for it. All water flows Easterly East of the continental divide. All water will flow Westerly West of the continental divide. I've been there and seen it, weird. \n\nAnother explanation would be the rotation of the earth. The water would be "pulled" toward the equator, where the largest mass of the earth's body would be.

Wind is just moving air which id technically a mixture of particles and gaseous molecules. The earth's rotational spin and pressure systems causes movement. These mixture is microscopic yet you feel the effect of the movement as the friction caused when brushing on your body and hence wind. You cannot see wind with the naked eye but a lot of different particles are found within the atmospheric composition.

the air gets thinner as you rise in elevation.  the thin mountain air doesn't trap the heat as well as the thick air near sea level does.

The wind would be blowing towards the north over the lake. This would push water on the surface of the lake towards the north. And you wouldn't even notice the difference in the level.

Gravity,it is often diffacult to tell which direction you are faceing, the teory is to whatch the saliver to see which way it goes.so you digg in the opposite direction and not bury your self ferther

Distance.  The closer together an area of high and low pressure the faster the wind will rush from the high pressure area into the low pressure area.

Basically, airplane uses the same aerodynamic forces as forces that lifting your hand, when you reach out your hand through the moving car window.\nLittle slope of your hand is enough to create air force that pushes your hand up or down depending of angle.\n\nSimilarly, wind speed can elevate your sun umbrella on the beach.\nOnly difference is that an airplane creating enough wind speed by own moving straight ahead and forcing the air to push his sun umbrella (in case of airplane – sun umbrella or sloping hand  is WING )
