'Beschreiben' (to describe) is an inseparable verb derived from 'schreiben' (to write). The prefix 'be-' makes the verb transitive and changes the meaning from 'schreiben' to 'über etwas schreiben' (to write about something, i.e. to represent something) or 'auf etwas schreiben' (to write on something).
Der Zeuge konnte den Täter genau beschreiben.
The witness was able to describe the perpetrator precisely.
The object of the verb reveals the meaning. If the object is a person, thing, or situation, it means 'darstellen' (to represent/describe). If the object is a geometric form (circle, curve), it means 'sich bewegen auf' (to move along). If the object is an empty surface (paper, board), it means 'mit Schrift versehen' (to cover with writing).
Er beschrieb seine Gefühle in einem Brief.
He described his feelings in a letter.
In the most common meaning, 'darstellen' (to describe/represent), 'beschreiben' (to describe) is often combined with these nouns: 'eine Person beschreiben' (to describe a person), 'einen Weg beschreiben' (to describe a route), 'ein Problem beschreiben' (to describe a problem), or 'seine Gefühle beschreiben' (to describe one's feelings).

The meaning 'sich auf einer Bahn bewegen' (to move along a path/orbit) is used almost exclusively in a scientific or technical context, for example in geometry, physics, or astronomy.

'erklären' and 'beschreiben' are both used when you talk about something with words. 'beschreiben' fits when you say what something looks like, what it is like, or how something happens. 'erklären' goes one step further: you make it understandable how something works or why something is the way it is. That is why you can describe a person, a place, or a situation without really explaining it. There is a risk of confusion especially at school and at work: for details and characteristics, you are more likely to use 'beschreiben'; for reasons, rules, and connections, you are more likely to use 'erklären'.
