These hypotheses will be based on past experience, readings, and coursework. Stress relationships in your notes. In such a chain, each link is the necessary consequent of that which precedes, and the necessary antecedent to that which follows. The rising of the sun is consequent on the rotation of the earth. It is the logical antecedent of morning light.
Morning light is in turn the consequent of sunrise and the antecedent of numerous other phenomena.
If we examine any link of the chain, we find that it has more than one antecedent and more than one consequent. The rising of the sun depends on the position of the earth's axis as well as its rotation, and causes morning heat as well as morning light. Use a hard pencil because it won't smear when wet or when rubbed. A couple of colors are often useful. Make copious, yet ligible and accurate notes in the field.
