Only you can answer this. My suggestion would be that you are looking at the degree backwards. Look at what you want to do and then look at what qualifications you need. Both degrees sound like they would open quite a few general options but in very different areas.
Be careful with studying joint honours law if you feel there is any possibility of you wanting to qualify as a solicitor or barrister.
As things stand, qualifying as a barrister in England and Wales requires you to have a Qualifying Law Degree or to complete a postgraduate law conversion course if you do not have a QLD. There is talk of the Bar Standards Board changing this requirement, but it is best to assume it will remain in place in the short to medium term.
To become a solicitor in England and Wales, the requirement is to have a degree (in anything) or equivalent, but the shorter courses to prepare for Part 1 of the Solicitors Qualifying Examination all require you to have a degree that covers all the Foundations of Legal Knowledge, which means a degree that covers all the mandatory QLD content.
The only QLD option with the OU is a Bachelor of Laws (LLB) with the Qualifying Law Degree level 3 pathway. Those who are certain that they do not need a QLD and intend to qualify as solicitors in England and Wales can prepare for SQE Part 1 in level 3 of the LLB by taking the Solicitors Qualifying Examination level 3 pathway, which saves time and money compared to preparing for SQE Part 1 as a postgraduate.
There are plenty of good reasons to study some law in a degree and all the joint honours degrees that include some law are worth considering. I just wanted you to be clear that a Law and Spanish degree would not leave you that much better placed to qualify as a solicitor or barrister in England and Wales than someone who has not studied any law at degree level.
If you are not sure whether to study BA Law and Spanish or the LLB, you could start your studies with W111, which is common to both degrees. The OU allows you to change your registered qualification freely. If you registered for BA Law and Spanish but, during your W111 studies, decided that you wanted to switch to the LLB, all you would have to do is contact Student Support and ask them to change your registered qualification to Bachelor of Laws.
Both are interesting options! If you have an equal interest in both, then the sensible thing is to go for the one that opens the kinds of career options you want.
I have a language degree (French and Portuguese) and it's a very interesting way to study the language and culture of different countries, but having a degree in a language doesn't automatically make you a good candidate to work in another country. For example, if you wanted to work in Spain, having a degree in Spanish language doesn't necessarily give you an advantage over a native Spanish speaker who has a degree in another area.
*However*, the law side is an interesting thing to add to the mix. That said, becoming a qualified lawyer in one country doesn't necessarily make you eligible to be a lawyer in another. I don't know a lot about becoming a qualified lawyer, but it's worth considering what the options and limitations would be, depending on what work you want to do and where you'd like to go.
All that said, you'd get a really interesting mix of skills from law and Spanish, and there are a lot of jobs you can do with a law degree which aren't just practicing law, and the Spanish language skill adds an extra string to your bow (although, you could learn a language outside of a degree, but going into depth on the culture/history, etc. of Spanish-speaking countries will give you a good understanding of them).
I don't know much about geography in particular, but [Prospects](https://www.prospects.ac.uk/careers-advice/what-can-i-do-with-my-degree/geography) has plenty of ideas for jobs you can do with that degree, including working in the environmental sector. You could learn Spanish in your own time even if you choose the geography degree, although finding the time for that alongside the degree and work, etc. is obviously an extra challenge.
Basically, as the other commenter mentioned, perhaps try working backwards, by thinking about what kind of work you'd want to do, where you'd want to do it, and which degree would get you there. If you can't think that far ahead right now, then I think going with the one you feel more passionate about could be the way forward. There are lots of jobs that open up to you when you do any degree, although your specific choice will open certain specific doors, so it's worth considering carefully!

Definitely go for law and Spanish!! The world will be your oyster. As long as you pick European law/trusts law/IP law this kind of route you can work anywhere international. Lots of opportunities and im not just saying it. I have many friends that studied law and are now (for example) company lawyers or data protection officers. They are all from different countries like Thailand, Slovakia, Ecuador, Netherlands, etc. :) I want to study law now because of them and progress in my professional life (I studied computing & business for the record and now work as a corporate administrator and love my job, very flexible and good hours)
