To study something is to examine it in hopes of grasping it. To grasp it is to learn it. Learning is the goal of studying.

The traditional way of forming the past tense is to add "-ed" to the verb. Thus "learned" is perfectly average. "Learnt" is just an alternate past form.

Or I could add that "study" means to work actively to get knowledge into your head.

"Learn" is what happens when knowledge gets into your head. Sometimes you learn from studying, but not always. A child who touches a hot stove quickly learns not to touch it again. He has learned it, but he has not studied.

"Learned" is more common in the US, and "learnt" is more common in the UK, but neither one is wrong. However, some American teachers try to make their pupils stop saying "learnt". There are several verbs like that, such as "burn" and "spill".
