GeoAwareIB: Dear EarthCacher,
The number one guideline for the EarthCaches is that they “must provide an earth science lesson”. In the case of this EarthCache, this is not the case.
1. EarthCache Description
An EarthCache provides an Earth Science lesson through a visit to a unique geological site, and generally focuses on one aspect of the site. The description and tasks combine to teach the lesson and highlight what is unique or interesting about the location. The text should provide accurate, clear explanations of what visitors will experience at the site. The cache page content should assume no prior knowledge of Geology, and be written at age 14 reading level. The logging tasks must relate to the specific geological lesson.
Common features such as rivers, mountains, meanders, streams will likely not be accepted unless the cache page content indicates what is unique about that particular location, and provides an appropriate lesson.
Some cachers use GPS devices with a limited amount of text. If your cache page is long, you may want to place the logging requirements near the top. Be concise so that cachers read the cache page, rather than just skim it.
2. Acceptable Sciences
EarthCaches focus on the solid earth and the processes that shape it.
Acceptable:
• Geological materials - Rocks, minerals, fossils, sands, soils, etc.
• Geological processes - erosion, weathering, deposition, volcanic activity, glacial action, etc.
• Geological land form evolution - glacial valleys, reverse topography due to rock properties, waterfalls with geological explanations, use of geological materials - building stones, etc.
• Geological phenomena (not included above) - impact craters, geysers, mineral springs, etc.
• Tools used by geologists - index fossils, rocks, historical geology sites.
Not Acceptable:
Biology, Botany, Zoology, Ecology, Atmospheric observations, Oceanographic observations, Geodesy (unless specifically linked to the location), Archeology, History (unless it has a geological theme), a building (unless it has a geological lesson), Engineering (unless it has a geological theme).
As a result I am archiving your EC.

Thank you.

What is the wind?

The Earth is surrounded by the atmosphere, which is made up of air. Air is a mixture of gas, and solid and liquid particles. Energy from the sun heats up the atmosphere and the Earth unevenly.

The wind blows because of differences in air pressure from one location to another. Wind blows from areas of high pressure toward areas of low pressure. If the high pressure area is very close to the low pressure area, or if the pressure difference is very great, the wind can blow very fast.

The air tries to balance out the low and high pressure areas – air particles move from areas of high pressure (cold air) to areas of low pressure (warm air). This movement of air is known as the wind.

Air pressure depends on the density of the air, or how close together its molecules are. You know that a hard rubber ball is more dense than a Styrofoam ball and that ice cream is more dense than whipped cream. Air lower in the atmosphere is more dense than air above, so air pressure down low is greater than air pressure higher up. Temperature also makes changes in air pressure. In cold air, the molecules are more closely packed together than in warm air, so cold air is more dense than warm air.

Wind Direction

Although wind blows from areas of high pressure to areas of low pressure, it doesn't blow in a straight line. That's because the earth is rotating and the wind is also influenced by the movement of the earth. As it turns on its axis the air does not travel directly from areas of higher pressure to areas of lower pressure. Instead, the air is pushed to the west in the northern hemisphere and to the east in the southern hemisphere. This is known as the Coriolis force.

How Wind Power is Generated

Humans take advantage of high grounds to use the wind on their benefit. With wind turbines humans can generate electricity. Simply stated, a wind turbine is the opposite of a fan. The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor.

Wind turbines manufactured today have power ratings ranging from 250 watts to 7 MW.
An onshore wind turbine with a capacity of 2.5–3 MW can produce more than 6 million kWh in a year – enough to supply 1,500 average EU households with electricity.

About the Earthcache

After exploring the area, you have to perform this five tasks:

a) At the GZ, you are in an area of low or high pressure?

b) To which direction are the wind turbines “looking forward”? Why do you think is that? Explain your conclusions.

c) Humans take advantage of the wind with wind turbines to generate wind power / electricity. From the "waypoint I" how many wind turbines can you count?

d) So you can look from the high, you many climbing steps do you see in the "ladder" ? (Use "waypoint I")

e) Finally, what is the name of the wind turbine at the GZ?

Also, and despite being optional , please take a photo in the GZ, with your GPS and show it with your log. (No spoilers please)

Send the responses via my geocaching profile and enjoy your visit.

You can also send e-mail responses and images to netuseraz (at) hotmail (dot) com before performing the log cache.

I will give feedback to authorize the log.

The most exciting way to learn about the Earth and its processes is to get into the outdoors and experience it first-hand. Visiting an Earthcache is a great outdoor activity the whole family can enjoy. An Earthcache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. Earthcaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to Earthcaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.
