Which two characteristics do all Jovian planets have in common?

Which planet takes more time to complete one rotation on its axis than to complete one revolution around the Sun?

The diagram below represents planets A and B, of equal mass, revolving around a star. Compared to planet A, planet B has a

Compared to the oceanic crust, the continental crust is (for your referense, felsic and granitic are the same thing, same with basaltic and mafic)

Which landmass is moving northward with Australia as part of the same tectonic plate?

Earth's internal heat is the primary source of energy that

The epicenter of an earthquake is located 6500 kilometers away from a seismic station. If the first S-wave arrived at this seismic station at 1:30 p.m., at what time did the first P-wave arrive?

The Aleutian Islands extend westward from southern Alaska to form the northern boundary of the Pacific Ocean. These volcanic islands were formed by the nearby

The cross section below represents a pattern of magnetic field reversals preserved in the igneous bedrock of the oceanic crust east of the Mid-Atlantic ridge.

Which cross section best represents the magnetic field pattern west of the Mid-Atlantic ridge?

The cross-sectional view of Earth below, which shows seismic waves traveling from the focus of an earthquake. Points A and B are locations on Earth’s surface.

Which statement best explains why only one type of seismic wave was recorded at location B?

Base your answers on the passage below. Crustal Activity at Mid-Ocean Ridges Mid-ocean ridges are found at one type of tectonic plate boundary. These ridges consist of extensive underwater mountain ranges split by rift valleys. The rift valleys mark places where two crustal plates are pulling apart, widening the ocean basins, and allowing magma from the asthenosphere to move upward. In some cases, mid-ocean ridges have migrated toward nearby mantle hot spots. This explains why mid-ocean ridges and mantle hot spots are found together at several locations.

Which type of tectonic plate boundary is located at mid-ocean ridges?

The map below shows a part of Earth’s surface. Points A through D are locations on the ocean floor.

At which location is the temperature of the ocean floor bedrock most likely highest?

The map below shows the Atlantic Ocean divided into zones A, B, C, and D. The Mid-Atlantic Ridge is located between zones B and C.

Which graph best represents the geologic age of the surface bedrock on the ocean bottom?

Which sequence correctly lists the relative sizes from smallest to largest?

Which set of events is most common along tectonic plate boundaries?

Convection currents happen in the mantle. The outer core heats magma around it and causes it to become less dense. Because the magma is less dense than the material around it, it starts to rise toward the crust. Since the crust is not hot, the magma starts to cool as it gets close to the crust. Since it is cooling, it gets denser and starts to sink back down toward the outer core.

Use the information above to answer the following question: Which of the following TWO things happen to magma causing it to rise?

What is the thinnest and outer most layer of the Earth, that we live on?

Which layer of the Earth is solid iron and nickel?

What was the name given to all the continents when they were joined as one super continent?

The luminosity of a star describes its ______________.

What color are the coolest stars?

Whether a star ends up as a red dwarf or a neutron largely depends on what characteristic of the star?
