Question

task 3: fossils
how are most fossils formed?
when dead organisms are exposed to the elements for a long time.
when organisms or their traces are buried by sediment.
when dead organisms are trapped in tree sap.

Explanation:

Fossils are formed when organisms or their traces are buried by sediment. This process protects them from decomposition and allows minerals to replace organic material over time, creating a fossil. Exposure to elements (first option) would likely destroy remains rather than fossilize them. Trapping in sap (third option) is a specific case (like amber fossils) but not the most common way most fossils form.

Answer:

When organisms or their traces are buried by sediment.
