Alphabe-Thursday(on friday)

Hello all you Lovely Literate Learners!! 
welcome once again to Alphabe-Thursday. 
This week over at Jenny's Place, we are all learning about the letter "I". Check it out!


Icebergs are essential

Essential to the lives of the Polar bears:

Polar bear populations are in decline. By 2050, two-thirds of the world's polar bears are likely to be gone.
  • Climate change, which is causing ice to thin and melt, is reducing polar bear habits.
  • Loss of sea ice leads to higher energy requirements to locate food.
  • Mortality rates are increasing. 42% of Alasakan cubs reach 12 months of age. This number was 65% fifteen years ago.

  •  about Icebergs

    Icebergs are enormous. They can be taller than the Statue of Liberty and as big as a small state. Normally, only a tiny part of an iceberg can be seen from the surface of the water. Thousands of these massive glacial chunks are formed each year and many are carried hundreds of miles by ocean currents until they gradually melt away. 

    • While icebergs float in frigid saltwater oceans, they are actually made of freshwater.
    • More than two-thirds of the Earth's freshwater exists as ice in the form of glaciers and ice caps.
    • Each year, there are enough new icebergs formed in Antarctica to supply freshwater to the world's six billion inhabitants and every industry on our planet for four months.
    • Antarctica and Greenland account for more than 98 percent of the world's ice-mass.
    • Icebergs drift at a rate of about 0.4mph (0.7km/h). The speed at which icebergs move is affected by many things, including their size and shape, ocean currents, waves and wind. 
     The Titanic's tragic collision with an iceberg in 1912 shows just how dangerous icebergs can be. The Titanic was such a massive vessel that passengers barely felt the impact as the iceberg ripped a gaping hole in the bottom of ship. The Titanic sank on its maiden voyage, but the glacial ice that doomed the "unsinkable ship" may have been more than 15,000 years old! Now, satellites carefully track these colossal ice cubes and create detailed charts to warn navigators about their constantly shifting locations (for an example, see http://www.natice.noaa.gov/products/iceberg/). 

    Icebergs essentially killed thousands of people

I just love Icebergs so beautiful and serene so dangerous

Su-sieee! Mac said...

I didn't know that icebergs are made from fresh water and supply us the world with so much water. I like the way you presented the info--easy to understand and fun to read. Thank you. :-)

I fist saw icebergs off the southern tip of South America - they are so beautiful!

Jo said...

Such a fascinating read ... Icebergs always look so beautiful and serene ... the danger lurks beneath

I have never seen an iceberg but have full intentions of doing so one of these days. Beautiful photos!

Teresa said...

Amazing! What an intelligent and informative post.

Splendid Little Stars said...

fascinating! I have never seen an iceberg in person, but I have hiked to a glacier field.

Jenny said...

Wow! What a wonderfully intriquing and interesting post!

I have always been fascinated with icebergs but I've been too lazy to look anything up.

This was wonderful. They are beautiful, aren't they?

Thanks for a great stop on our little journey through Alphabe-Thursday's letter "I".

Really, really neat!
