What traps heat from the sun on Venus, making it much hotter than Earth?

• Its distance from the sun

• Its thick atmosphere

• Its volcanic activity

• Its magnetic field

What did Gerya think might allow melted rock called magma to move toward the surface more easily on Venus?

• Thicker crust

• Thinner crust

• Higher gravity

• Lower gravity

What did the photo taken by the spacecraft Venera show?

• The surface of Mars

• The surface of Venus

• The surface of the Moon

• The surface of Earth

What is the main purpose of using models in scientific research according to the text?

• To create new planets

• To get evidence about things that are difficult or impossible to observe directly

• To travel to other planets

• To predict weather patterns

Why did Gerya think the top rock layer on Venus might be thinner than the top layer of Earth's crust?

• Because Venus is closer to the sun

• Because Venus has more volcanic activity

• Because Venus's atmosphere is thicker

• Because Venus's surface temperature is higher

What did Gerya build to test whether the high temperature of Venus's surface and the planet's thin crust make it possible for novae to form there?

• A spacecraft

• A telescope

• A computer model

• A satellite

What did Gerya's computer model represent?

• The surface of Mars

• The surface of Venus

• The surface of Earth

• The surface of Jupiter

What evidence did Gerya's model provide about novae on Venus?

• That they were formed by meteor impacts

• That they were formed by volcanic eruptions

• That they were formed by a combination of high surface temperature and a thin rock layer

• That they were formed by tectonic plate movements
