The video explains the formation and discovery of fossils, focusing on dinosaur fossils. Fossils are remains of ancient animals or plants, often preserved as bones or imprints. The process of fossilization involves the decay of flesh, sediment covering bones, and the eventual formation of rock molds. Over time, these molds fill with minerals, creating solid rock fossils. Fossils can be exposed through natural events like earthquakes or erosion, but many remain buried, requiring paleontologists to excavate them.

What are fossils primarily composed of?

• Metal

• Wood

• Plastic

• Stone remains of animals or plants

How can a woolly mammoth be preserved for thousands of years?

• By being covered in mud

• By being buried in sand

• By being exposed to sunlight

• By being trapped in ice

What material is formed when tree sap hardens?

• Granite

• Limestone

• Coal

• Amber

What happens to a dinosaur's flesh after it sinks to the bottom of a river?

• It becomes fossilized immediately

• It remains intact

• It is eaten by smaller creatures or rots away

• It turns into stone

What covers the dinosaur skeleton over many years?

• Lava

• Sediment

• Ice

• Water

What is the term for the open space left by washed away bones?

• Fossil cast

• Sediment layer

• Natural mold

• Amber

How do tiny rock pieces contribute to fossil formation?

• They erode the sediment

• They create new bones

• They fill the natural mold

• They dissolve the bones

What natural events can cause fossils to rise to the Earth's surface?

• Earthquakes or mountain formation

• Floods

• Tornadoes

• Volcanic eruptions

What role do paleontologists play in fossil discovery?

• They dig and uncover fossils

• They create fossils

• They destroy fossils

• They sell fossils

Why might some fossils remain buried for a long time?

• They are in remote locations

• They are invisible

• They are under layers of rock

• They are too small to find
