Some websites that I use for geography [lessons + revision] - a mix of summary notes websites, statistics, geo-located data and other goodies :D enjoy! Hope you find something useful! 

I’ve only put my faves tbh but ** = I’ve used this a lot A LOT 

Scribd: honestly some docs on here are so useful for help structuring your own notes etc. [our teacher uses this one for example for the glossary]

**Sporcle: i use this to test my place knowledge! [i’ve linked you to the world one, but you can find other continent specific ones too]

[Alternative to above that I personally haven’t used much but it looks decent so]

World Mapper: Really cool maps and omg countries look so funny distorted heu heu (HONESTLY SO USEFUL AND VISUAL) [i’ve linked to the old site haha]

**Gapminder: I’ve linked you to the program itself [so so so good omg for global trends over time GENIUS] but Hans Rosling is a cinnamon roll go watch the videos too!!

Information is beautiful: I love infographics okay fight me on this. You could have a look at this one and oh here’s the blog and just have an explore tbh [there’s isn’t a huge number of infographics on here tbh it’s a shame but i guess they’re trying to sell the book so fair]

**Datashine (UK centric): UK Census 2011 info geo-located and ahhh it’s so useful 

they also have this one on commuting if you’re about that life

*******CIA World Factbook: ALL THE STATS! LIFESAVER! 10Q America! (that maths pun stop me pls) 

Generally amazing website that is succinct and you could probably find so much on here tbh

Quizlet: really useful resource!! flashcards!! i love this site!! (and there’s an app hehe) test yourself on case studies etc!!

[tip: you can duplicate ppl’s flashcards and edit them if there’s anything you want to add!] 

BBC bitesize ayyy for gcse peeps! (and in general too :) ) 

S-cool [linked again to the gcse site cuz that’s what was bookmarked but they have an a-level section too!] Some real concise notes tbh and may be useful even if you aren’t studying gcses/alevels! :) 

my other masterpost/ramble hybrids are all (there’s like 2 others lol) here and feel free to come rant at me (or just talk lel) if any links don’t work etc! 

in hindsight a better header for this would have been ‘resources i rely on way too much for geography’ (*´◡`) 

On October 8 a privileged few could see auroras in abnormally low latitudes, as the spectacular pictures above taken in Wales and Northern England.

MARTIAN STORMS - Seen in 1977 by the Viking 2 Orbiter

“Like its predecessor, the Viking 2 mission consisted of a lander and an orbiter designed to take high-resolution images, and study the Martian surface and atmosphere. Both the Viking 1 and 2 landers benefited greatly from their orbiting counterparts, which snapped images that helped mission controllers navigate the landers to safe landing sites.”

This particular image was taken by the Viking 2 Orbiter and shows a massive dust storm on the red planet. This spectacular storm can be seen on a global scale. The Viking 2 mission would end 3 years later on April 11, 1980.

The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the Ω-shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in Hα. EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIFs above show multiple energetic jets in three different wavelengths. The light has been colorized in red, green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.

Five women shaking up the science world

From pushing boundaries to defying stereotypes - five women who are breaking barriers in science.

The gender divide in science is cultural rather than anything to do with women’s brains and some countries do much better than others, she says.

In astrophysics southern European countries like France, Spain and Italy do much better than northern European countries like Germany and The Netherlands, for instance.

“In all those countries the proportion of women is going up but the pattern has stayed the same, which is interesting,” she says.

“The progress is slow, things are changing gradually.”

Her advice to women in science? “Don’t be daunted, hang in there, work hard, of course, be courageous.”

Would It Be A Bad Thing to Wipe Out A Species … If It’s A Mosquito?

Mosquitoes have a nasty reputation.

The species Aedes aegypti, for example, is currently responsible for spreading the Zika virus through the Americas and also infects humans with dengue fever, chikungunya and yellow fever.

This raises the question: Should there be an effort to get rid of Aedes aegypti for good?

“There’s been lots of debate in the last 10 years whether we should eradicate mosquitoes, or at least the 100 species or so that serve as disease vectors for humans,” says David Magnus, director of Stanford University’s Center for Biomedical Ethics. “If you look at the science, the majority [of scientists] think we could probably eliminate mosquitoes without too much harm on the environment.”

Making your own personalised guides is quite different from your normal note-taking. Study guides are more exam-oriented, instead of merely summarising and organising information. It is a tool to help you to study for your exams, and to guide you through answering exam questions. This how-to guide is a summary of my learning experiences in both high school and college, so I hope this can help everyone here.

Goals for the study guides

It has to include everything on the syllabus for the examination

Omit things that are not going to be useful/helpful in exams

There are things that may be very informative, but if they have no relevance to the exam, it’s better to take them out of the study guide

Basically, the goal of making this study guide is to have one booklet/notebook that contain things you have learnt in that course, and most importantly, everything you need for the exam.

That means you (supposedly) wouldn’t have to refer to any other materials unless specified in the study guide 

Making this booklet will help you to summarise and analyse information - a great way to study

Materials that you need

If you are in college, lecture notes are usually the most important material you should refer to when studying for exams. If you are in high school, textbooks are more likely to prevail. It depends on your course structure and the way your teacher/lecturer teaches.

Past papers / practice papers are great guidance for you when making study guides, because they help you to understand what will be on the exam paper, and most importantly, how you could answer the question.

Important tip: while making your own summary of the knowledge is useful, write down the model answer from the past paper in your study guide instead. That’s the way you should answer the question related to that topic in the exam, so you shouldn’t waste time putting in and memorising information that is not helpful.

For college students: tutorial questions usually offer great guidance as to what is going to appear in the exam. Putting those in the study guides is usually very helpful.

Organising the study guides

Here are a few tips when organising your notes:

Put a red star next to topics that you think are going to come up in the examination

Circle topics that you don’t understand / fail to grasp when making the study guides

Definitely use bullet points if possible

Highlight key words with definition in one specific colour, or anything that requires direct recitation

Because this is what you will study for the exam, also put down tips that are going to help you with the exams. (You can either draw a box to alert yourself or use a post-it note for these).

Answering structure / attack plan for common exam questions

Some common mistakes previous students made in the exam (which is usually brought up by the teacher / lecturer)

Important concept / clarification of misunderstandings

Remember to leave a page for each chapter and write a summary of it during revision

This will help you to understand the flow of the chapter and it is a great way to recall the information you have just organised
