It allows them to see how organisms have changed over time

It allows them to see how organisms have remained the same over time

According to the diagram, which of the following statements is true?

Fossil C is younger than Fossil D

Fossil C and D are the same age.

How can fossils tell us about Earth's past?

Fossils give clues about environmental changes where the organism lived.

Fossils can be used to date the time period of rocks and rock layers when the organism lived.

Fossils can give clues of changes in the organism's body structure over time.

What do most scientists think caused the mass extinction of dinosaurs and other organisms at the end of the Cretaceous period?

an object from space struck Earth

volcanic eruptions covered large areas with lava

an ice age covered most of Earth with ice

The dinosaurs ate too many other organisms and then starved

What is absolute dating

the age when the rock was formed

a range of rock compared to other rocks

Which of the following is NOT an accepted criterion for a mass extinction event?

The cause of the mass extinction must be obvious.

The event must have occurred in a relatively short time frame.

The extinction involves multiple lifeforms and is widespread.

A significant part of life on Earth became extinct.

Evidence on earth of solid rock older than 3.8 billion years is lacking because

Older rocks have been lost due to erosion and plate tectonics

Those rocks haven't been found yet

In the early Archaean eon life forms appeared on earth. Evidence for this are

Micro fossils of bacteria in the form of stromatolites

Eurkaryotic cells found trapped in amber

Multicellular algae and the first animals evolved towards the end of the proterozoic eon. This was most likely due to

Increased oxygen levels in the atmosphere due to photosynthetic organisms

Decreased oxygen levels in the atmosphere due to photosynthetic organisms

At the end of the proterozoic eon, reveals evidence of a diversity of multi cellular animals - the fossils are mainly of

Small soft bodied sea creatures

The Cambrian explosion

Showed a dramatic increase in the number and complexity of life in the oceans

Showed a reduced diversity in fossils
