Dynamic Planet B/C

There is usually a math portion involved in these tests as well, which ask you to know how far a plate is going, usually centimeters per year. I would make sure you know how to do that, and maybe with significant figures as well. There may also be questions dedicated a lot on to America's hot spots, specifically Yellowstone and Hawaii. Learn those and their histories. Lastly, know isostasy, it's more than likely going to appear on the test, and usually those are some of the harder questions. Getting those may give you the edge.

That's all good advice, I think the original question said the person was going to compete in DP in an invitational this Saturday so it won't help them very much anymore, but good advice for the next person who has to learn this event in a day, lol.

Thank you everyone! My sister ended up placing in the middle, which is decent considering she only had a day to prepare!

Congrats to her! I had a somewhat similar thing where my sister decided to prepare for DP tryouts at her school in a day, but she also had the advantage that I gave her my Nats notes sheet. It's really impressive to have managed a decent understanding of the event starting from scratch, and competition is always harder than tryouts...

Hey, you guys! It's my first year in science olympiad soooo i don't really understand some of the terms and i can't find anything online really about one topic which is " Continental drift's role on opening and closure of ocean gateways and land bridges, with specific reference to ocean circulation changes, climate changes, and biotic migrations " can someone please leave some links or something? thanks!

Hello! Can someone possibly help me determine the meaning of letter F: "Continental drifts role on opening and closure of ocean gateways/ land bridges, with specific reference to ocean circulation changes, climate change, and biotic migrations"? I took some notes on the land bridge theory, but I'm completely lost on everything else. What do I search up to find information on this topic?
Thanks in advance!

I can remember people being weirded out by that bit last year as well, I think part of it might be the ability of the West Wind Drift to circulate after the other continents separated from Antarctica, and another bit is talking about speciation as a result of physical separation of species, but I haven't yet found any good sources on this bit.

So far, in my notes, the only thing I have are what land bridges and ocean gateways are, and how they relate to biology in general. I know it doesn't sound much, but you should try and google "ocean gateways" and find something that has even the slightest bit of information. This is definitely one of the most ambiguous topics for dynamic planet, and I rarely see questions like this appear; that doesn't mean your next competition definitely won't include it though, as anything goes.

Oh my gosh just saw this lol but i have like no notes on any of this soooo the whole thing is confusing to me

In the rules its talks about hydro-thermals and hydrocarbons, but what are they and what could be tested on them?

Hydrocarbons sounds like what it is - molecules of hydrogen and carbon. They can form in things like hydrothermals, which are heated water vents. The hydrocarbons can be used as evidence for certain reactions.

That's just the general summary, so I'm not sure if this would be of much use. You'll have to look into it more from there.

Hydrocarbons are one of the primary things in oil (petroleum), so basically think about petroleum-forming conditions when it asks about hydrocarbons, and how those might be affected by tectonic features.

Also, about hydrothermals, I think it's talking about not just hydrothermal vents, but all circulation of water through seafloor sediments and basalts.

This is one part of the rules that changed since last year, so I don't really know what types of questions are normally asked about it.

Dose anyone know what the stars are for?

Is anyone out there besides me?

Which stars do you mean? Is the dynamic planet thread the right place to be asking this?

If you are wondering about the stars under your username, those stars are not really important.
