Question

Scientists have found evidence for climate change by analysing sediment. The sediment contains preserved __________ from plants, which tells them what species were alive at a certain time, and thus what the conditions were like. What word completes the sentence?

​

Answer 1

"Pollen" is the word that completes the statement.

Step-by-step explanation:

Scientists can recreate previous plant patterns and climatic conditions by studying pollen grains caught in sediment strata. Scientists can deduce what plants were prevalent in the region at a particular period and how the temperature and ecosystem may have changed over time by recognizing various kinds of pollen. This form of analysis is known as pollen analysis or palynology, and it is a valuable tool for analyzing long-term climate change.
