Scientists found the fossils of whales and other marine animals in the sediments of the Andes mountains in Southern Chile. These fossils were discovered at altitudes more than 1500 m above sea level. These animals are determined to have died 15 – 20 million years ago. 1. Describe the events and geological processes that would have led to these whale fossils ending up high on the mountain range.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

maybe because its impossible for balloons to lift a whole entire house.
