Earth Science 1st Semester Final 2526

Which event is thought to have formed the Moon about 4.5 billion years ago?

• A comet striking the Moon

• A Mars-sized body colliding with Earth

• The Sun pulling rocks from Earth’s crust

• Earth splitting into two smaller planets

What evidence supports the Giant Impact Hypothesis?

• The Moon has a large iron core like Earth

• The Moon is made of ice and gas

• The Moon and Earth have similar rock compositions

• The Moon formed at the same time as the Sun

Why does the Moon lack a large iron core compared to Earth?

• It formed mostly from Earth’s outer layers during the impact

• It lost its core due to solar winds

• It originally had no metals at all

• Its iron core sank into Earth’s mantle

If you were labeling a diagram of the Giant Impact Hypothesis, where would you place the “debris”?

• Inside Earth’s inner core

• In orbit around Earth after the impact

• Deep within Earth’s mantle

• At Earth’s surface, unmoving

Computer models of the Giant Impact Hypothesis show that

• the Moon formed from debris after a Mars-sized body collided with Earth

• the Moon was captured by Earth's gravity from another part of the solar system

• the Moon formed at the same time and place as Earth

• the Moon is a fragment of a destroyed planet beyond Mars

Which reasoning BEST explains why these models support the hypothesis?

• The models exactly predict the Moon’s surface features

• The models show a process that matches the evidence we see today

• The models prove Earth’s crust and mantle are made of the same material

• The models explain why Earth’s gravity pulls on the Moon

A student draws the Giant Impact Hypothesis but forgets to include the debris orbiting Earth. What key step of Moon formation is missing?

• The impact of Theia with Earth

• The accretion of debris into the Moon

• The layering of Earth’s crust, mantle, and core

• The presence of convection currents in the mantle

What are tectonic plates?

• Layers of gases in Earth’s atmosphere

• Large slabs of Earth’s outer shell that move on the mantle

• Layers of molten rock inside Earth’s core

• Rocks formed at volcanoes

What drives the movement of Earth’s tectonic plates?

• Earth’s rotation on its axis

• Gravitational pull of the Moon

• Convection currents in the mantle

• Winds in the atmosphere
