I think there are supposed to be multiple choice questions, but the amazon rainforest is an extremely unexplored piece of land. Scientists believe there may be cures for certain diseases inside, like cancer, from a plant or an animal that we have yet to discover.
Answer:
1) sun and moon
2) spring
3) neap
4) twice
Explanation:
Given the sentences in the question and the knowledge of Tide, the sentences would be fully witten as:
The pull of gravity of SUN and MOON causes Earth's crust and oceans to bulge. This creates high and low tides. SPRING Tides occur when the Sun, the moon, and Earth are nearly aligned. NEAP Tides happen when the Sun and the moon are at right angles to each other. Each of these special tides happens TWICE in a lunar cycle.
That the picture was inspired on a full moon.
