WELCOME BACK!!!
Over the last twelve months, I have had several questions posed about our journey and in particular about the vastness of the ocean and the power it holds.
Over the coming months the crew will be learning how to navigate, communicate and understand the mechanics of the R45 rowing boat and in addition I have made it my mission to learn more about the Ocean that is so vast, it covers 70% of the Earth surface.
GETTING READY FOR YOUR NEXT STEP
If you are a friend, family member, loved one, supporters from afar, why not join us in having an attempt at Blackburn’s quiz….
So the next few steps are very simple. Over the next few pages there are 20 questions for you to ponder, mull over and hopefully attempt to answer.
Towards the later end, you have the answers to the questions. I have tried to keep the quiz light-hearted fun and for all the family to join in.
Do you think you can answer all 20 Questions? It would be great to hear your results and any questions that you either found hard or easy?

I hope you’ve got your answers ready…
1 - 20% - The Atlantic Ocean covers approximately 20 percent of the Earth’s surface, the Atlantic Ocean is the second-largest basin in the world, following only by the Pacific.
2 - FALSE - When you add an ice cube to your glass, the water level goes up. But when that ice cube melts there is no additional change in the water level. The same process applies to sea-level rise. Glaciers hold ice on land. When they start to melt and break apart, that ice enters the marine environment. Land-based ice can melt the ocean as liquid water, or large chunks can break away in the form of icebergs. When these icebergs enter the water sea level rises.
3 - The famous image of a sprout of water rising as a whale leads meany to believe whales are expelling water into the air. But whales don’t have water in their lungs. Blowholes work like nostrils'; the spray is just them exhaling air. Then what makes the spray? Some of it may be water on the top of the whales’s head when it surfaces, and some is mucus, just like when you blow your nose.
4 - While this potential origin of the word news seems plausible enough, it isn’t true. The truth is, the word news can be traced back to late Middle English around the 14th century as a plural for the adjective ‘new’ or ‘new thing’. This is a somewhat rare instance of an English adjective becoming a noun when made plural. Making this leap from ‘new’ to ‘news’ in English is thought to have been influenced by the Old French ‘nouveau’, meaning ‘new’. ‘Nouveau’ in its plural feminine form becomes the noun ‘nouvelles’ meaning ‘news’.
5 - Sailors call the latitudes between 40 and 50 degrees south of the equator the roaring forties. The Roaring Forties take shape as warm air near the equator rises and moves towards the poles.
6 - 50-80% - Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton.
7 - Seasickness is a result of a conflict in the inner ear, where the human balance and mechanism resides, and is caused by a vessel’s erratic motion on the water. Inside the cabin of a rocking boat for example.
8 - Cigarette butts continue to rank among the most common types of marine debris found. The Ocean Conservancy’s 2018 International Coastal Cleanup Report stated that 2,412,151 cigarette butts were collected worldwide in 2017.
9 - The horse latitudes are regions located at about 30 degrees north and south of the equator. These latitudes are characterized by calm winds and little precipitation.
10 - While scientists estimate that 91 percent of ocean species have yet to be classified, the global scientific community continues to amass as much knowledge as possible about ocean life.
11 - In the beginning, the primeval seas were probably only slightly salty. But over time, as rain fell to the earth and ran over the land, breaking up rocks and transporting their minerals to the ocean, the ocean has become saltier.
12 - Water - While sound moves at a faster speed in the water than in air, the distance that sounds waves travel is primarily dependant upon ocean temperature and pressure.
13 - The water temperature of the Atlantic Ocean varies between -2 and -28 degrees celsius (polar-equator).
14 - 36,200 feet.
15 - In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land.
16 - 1000 meters.
17 - Over vast periods of time, our primitive oceans formed. The water remained a gas until the earth cooled below 212 deg Fahrenheit. At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that are now our oceans.
18 - The Mid Atlantic Ridge.
19 - Atlas - Atlas was the titan who had to stand on the edge of the earth and carry the heavens (celestial spheres).
20 - Canada.
I hope you enjoyed my quiz and you’ve learnt something new.
