Is she a talker in general, but doesn't ask questions, or is she just generally more reticent? If she is generally quiet, it may be that she prefers to keep her questions to herself. Some children have a much richer interior life than is apparent even to those who are closest to them. You've already established that she is thoughtful, and makes good connections, so the capacity for curiosity is there. You also mention that she is active, and enjoys
doing things, which is quite normal for a preschooler. She may be exploring and inquiring in her active play. Perhaps actions speak louder than words.
