Front

What is the Permian Period?

Back

The Permian Period is a geological time period that lasted from about 299 to 252 million years ago, known for the largest mass extinction in Earth's history.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, such as carbon dioxide (CO2) and methane (CH4), contributing to the greenhouse effect.

Front

How do volcanic eruptions affect the atmosphere?

Back

Volcanic eruptions can release large amounts of ash and gases, including greenhouse gases, which can lead to climate change and affect global temperatures.

Front

What is the geological time scale?

Back

The geological time scale is a system of chronological dating that relates geological strata to time, used to describe the timing and relationships of events in Earth's history.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of ancient organisms, often found in sedimentary rock, providing evidence of past life.

Front

What does it mean for species to share a common ancestry?

Back

Sharing a common ancestry means that different species have evolved from a shared ancestor, indicating a relationship in their evolutionary history.

Front

What is the significance of rock layers in geology?

Back

Rock layers, or strata, provide important information about the Earth's history, including the age of fossils and the environmental conditions at the time of their formation.

Front

What is the importance of the arrangement of bones in skeletal structures?

Back

The arrangement of bones can indicate evolutionary relationships between species, showing similarities and differences that suggest common ancestry.

Front

What is mass extinction?

Back

Mass extinction is a widespread and rapid decrease in the biodiversity on Earth, often caused by catastrophic events or significant environmental changes.

Front

What evidence do fossils provide about evolution?

Back

Fossils provide evidence of how species have changed over time, showing transitional forms and helping to trace the evolutionary lineage of organisms.
