Gamburtsev 'ghost mountains mystery solved'

The Gamburstev mountains are the same size as the Alps and are buried beneath the Antarctic Sea. The Gamburstev was discovered in 1950s and was a great surprise. The researches tell that this range was formed over a billion years ago. The Gamburtsevs are really important because they are believed to be the location where the sheet we know today is Antarctica. " Surveying these mountains was an incredible challenge, but we succeeded and it's produced a fascinating story,: quoted.Dr Fausto Ferraccioli. Searching these mountains history is helping scientists understand not just past changes on Earth but they could possibly find scenarios that could happen in the future. 

Dr Fausto Ferraccioli was a principle investigator for Antarctica's Gamburtsev Province project.They were trying to find a hidden shape of a mountain system using ice-penetrating radar. The other instruments they used were the seismometers and they could record the local gravitational and magnetic fields on the ice sheet surface. The AGAP team believes all this data that they found could make a huge story for Gamburstev's creation and persistence through geological time. This was a story that started over a billion years ago. It was long before when complex life had formed in the world, after this happened they continents were sliding which ended up creating a giant landmass called Rodinia. This was kind of an explosion and it pushed up the mountains and also produced and underlying think, thick root on the crust. It's believed that about 250-100 million years ago, when dinosaurs roamed the planet, the crust started to pull apart in a series of rifting events close to the old root. To some extent , the AGAP's survey has actually depressed this quest. The radar data has indicated the base of the sheet has been severely disrupted by water that has been freshly frozen, layer upon layer, on to the bottom of the ice column.

I choose this article because it was really interesting for me because of what people can find about the past in cool ways, however it didn't relate to are unit at the moment, it was quite fun to read and write about.  I think this is reliable because they have so many evidence. For example graphs, charts and pictures and also the AGAP team is really professional. This relates to science because what people are trying this day are really different. The researches try to find the past and predict the future one day.

Where's The Evidence Lab?

Title of The lab: Where's The Evidence

The guiding question: What are some signs that a chemical reaction has taken place?

Your hypothesis: I think that when a chemical reaction or change in the water it starts sparkling and making some soda sounds. It might combust.

List of the Materials used:
1) Na2Co3- Sodium Carbonate
2)CaCl2- Calcium Chloride
3)HCl- Hydrochloric Acid
4)CuSO4- Copper Sulfate(acid)
5) Aluminium Foil
6)Zinc Pieces
7)Baking Soda
8)Vinegar
9)Magnesium Tablets
10)Spatula
11)Graduate Cylinders
12)Stirrer
13)Candle/matches
14)Goggles
15)Beakers/baby food jars
16)Starch
17)Iodine
18)* thermometer

Table of Analysis:


Reaction
Observations Before Reaction
Predictions
Observations During Reaction
Observations After Reaction
1)Baking Soda(Soda bicarbonate + vinegar)
It will bubble up.
It will turn white.
It bubble up and foams.
The vinegar has gas in it.
2)Copper Sulfate + Sodium Carbonate solutions
That is could bubble up and still stay blue.
It would be freezing.
It starts bubbling.
It stops a bit on the bottom and on the top.
3)Zinc piece + HCl
Liquid is clear.
Zinc could change color.
Bubble up and zinc changes color.
Fizzes the zinc and looks like its dissolving.
4)Calcium Chloride + Sodium Carbonate
Both liquids are clear.
Because both liquids are transparent it will turn white.
Turns white.
Stays the same.
5)Copper Suflate + Aluminium Foil Piece
Blue liquid and foil piece.
The aluminium foil piece will change color.
The foil changes color.
Aluminium turns black.
6)Starch + Iodine (I2)
Iodine is red (looks like blood) Starch is white powder.
It will change to a dark color.
Changes color. Gets darker and darker.
The color is darker and you see starch at the bottom.
7)Sugar + Heat
The color of the sugar would change.
It will change to caramel.
Sugar melts.
Sugar becomes brown and made caramel.
