Investigating Landforms on Venus

What are novae on Venus?

• Raised domes with cracks reaching outward in all directions

• Large craters filled with water

• Flat plains with no features

• Tall mountains with snow caps

Why might a thinner crust on Venus help novae to form?

• It allows melted rock to move toward the surface more easily

• It makes the surface colder

• It prevents cracks from forming

• It increases the planet's gravity

Which spacecraft took a photo of the rocky surface of Venus?

• Venera

• Apollo

• Voyager

• Curiosity

What feature makes novae easy to see from above?

• Cracks reaching out from their centers in all directions

• Bright colors

• Large lakes

• Tall trees

Explain why scientists cannot directly observe how novae formed on Venus.

• Venus is millions of kilometers from Earth and the novae formed millions of years ago

• Venus is too cold for spacecraft

• Novae are underwater

• Venus has too thick of an atmosphere

What evidence did Gerya use to support his idea about the formation of novae?

• A computer model showing how high temperature and thin crust could form novae

• Samples of rock from Venus

• Photographs of Earth's volcanoes

• Data from Mars that had similar formations

Compare the average surface temperatures of Earth and Venus.

• Earth: 14°C (57°F), Venus: 462°C (864°F)

• Earth: 100°C (212°F), Venus: 0°C (32°F)

• Earth: 462°C (864°F), Venus: 14°C (57°F)

• Earth: 0°C (32°F), Venus: 100°C (212°F)

What evidence would support Gerya’s idea about how novae on Venus were formed?

• If features like novae formed in his computer model

• If the model produced only flat surfaces

• If the model showed no changes over time

• If the model created mountains instead of domes

What method did Gerya use to validate the results of his model?

• By comparing the model's predictions to actual geological structures on Venus

• By making assumptions

• By using similar data from Mars

• By checking the model's accuracy compared to other habitable planets data

What did Gerya find when he compared the domes in his computer model to those on the surface of Venus?

• They were the same size and shape as the novae observed on Venus

• They were much smaller than the novae on Venus

• They were completely different from the novae on Venus

• They were only found on Earth
