Holes larger than this will invite larger birds and other predators to invade the box, which can be a danger to the chicks or prompt the invaders to take over the box and evict the current residents. The following chart will help select a birdhouse appropriate for housing a particular species. We not only give you an idea of the specification requirements of the house or platform, but also give you some tips about where and how high to mount it.
Why does the ocean not boil or freeze solid in different regions of the world? Heat is transported by oceanic and atmospheric circulation The pycnocline isolates the majority of the world ocean from heating and cooling brought on by solar energy fluctuations What is the main reason for the stratification in the north polar waters?
Ocean water, with an average salinity of 35 psu, freezes at -1.94 degrees Celsius (28.5 degrees Fahrenheit). That means at high latitudes sea ice can form. The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit).90 % of the total volume of ocean is found below the thermocline in the deep ocean. The deep ocean is not well mixed. The deep ocean is made up of horizontal layers of equal density.f you want to know about the temperature of the ocean, you have to learn about the parts of the the ocean first. The top part of the ocean is called the surface layer. Then there is a boundary layer called the thermocline. The thermocline separates the surface layers and the deep water of the ocean.
