What is the oldest rock found near a mid-ocean ridge?

Back

The oldest rock is found at point O.

Front

List the evidence that supported Alfred Wegener’s theory of continental drift.

Back

1. The fit of the continents (e.g., South America and Africa). 2. Fossil evidence (e.g., identical fossils found on different continents). 3. Geological similarities (e.g., mountain ranges and rock formations). 4. Paleoclimatic evidence (e.g., glacial deposits in now tropical regions).

Front

Which layer of Earth is the source of lava that erupts from volcanoes?

Back

The source of lava is the Mantle/Asthenosphere.

Front

Which fossil is relatively the oldest?

Back

The oldest fossil is the Trilobite.

Front

What property of a rock can be identified using its radioactive isotope content?

Back

The age of the rock.

Front

What is continental drift?

Back

Continental drift is the theory that continents move over geological time.

Front

What evidence supports the theory of plate tectonics?

Back

Evidence includes the fit of continents, fossil distribution, and seismic activity.

Front

What is the significance of the Mantle in geology?

Back

The Mantle is the layer of Earth where magma is generated, leading to volcanic eruptions.

Front

Define paleoclimatic evidence.

Back

Paleoclimatic evidence refers to data from past climates, such as glacial deposits found in tropical regions.

Front

What are fossils?

Back

Fossils are preserved remains or traces of ancient organisms.
