Which layer of the Earth makes up the largest volume?
Inner Core
Outer Core
Mantle
Crust
The mantle extends from just beneath the crust to the outer core and accounts for about 84% of Earth's volume. It is composed of silicate rocks that are rich in iron and magnesium. Heat and pressure in the mantle drive plate tectonics through convection. .
What is the most abundant gas in Earth's atmosphere?
Argon
Carbon Dioxide
Nitrogen
Oxygen
Nitrogen makes up about 78% of Earth's atmosphere by volume. Oxygen is the second most abundant at around 21%. Argon and carbon dioxide together account for less than 1%. .
The process by which water, wind, or ice transports soil and rock particles is called what?
Deposition
Weathering
Erosion
Sublimation
Erosion refers to the movement of soil and rock by natural agents like water, wind, or ice. Weathering is the breakdown of rock in place. Deposition occurs when those particles settle after being transported. .
Which instrument is used to measure atmospheric pressure?
Hygrometer
Barometer
Thermometer
Anemometer
A barometer measures atmospheric pressure, indicating changes in weather patterns. It was invented by Evangelista Torricelli in the 17th century. Thermometers measure temperature, hygrometers measure humidity, and anemometers measure wind speed. .
What primarily causes the rise and fall of ocean tides?
Earth's rotation alone
The Moon's gravitational pull
Strong ocean currents
Sunlight heating the surface
Tides result from the gravitational forces exerted by the Moon and, to a lesser extent, the Sun. The Moon's gravity pulls ocean water toward it, creating a bulge. As Earth rotates, different areas pass through these bulges, causing high and low tides. .
Off the coast of which Australian state is the Great Barrier Reef located?
Victoria
Queensland
New South Wales
Western Australia
The Great Barrier Reef lies off the coast of Queensland in northeastern Australia. It is the world's largest coral reef system, stretching over 2,300 kilometers. The reef supports vast biodiversity and is visible from space. .
Marble is classified as which type of rock?
Metamorphic
Volcanic
Sedimentary
Igneous
Marble forms when limestone is subjected to heat and pressure, recrystallizing into a denser rock. This metamorphic process alters the mineralogy and texture of the original sedimentary rock. Marble is known for its characteristic swirls and veining. .
The Earth's core is composed primarily of which element?
Oxygen
Magnesium
Silicon
Iron
Seismic studies and density calculations show that Earth's core is mostly iron, with some nickel and lighter elements. The outer core is liquid and generates Earth's magnetic field through convection. The inner core is solid due to immense pressure. .
Weathering differs from erosion in that weathering primarily involves what process?
Transport of sediment
Deposition of materials
Formation of new minerals
Breakdown of rock in place
Weathering is the in situ breakdown of rocks by chemical, physical, or biological means. Erosion, by contrast, involves transporting those weathered materials. Deposition happens when transported sediments settle. .
Which phenomenon is characterized by unusually warm ocean temperatures in the eastern Pacific?
La Niña
Madden - Julian Oscillation
Indian Ocean Dipole
El Niño
El Niño is marked by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean. It disrupts global weather patterns, often causing floods or droughts. La Niña is the opposite phase, with cooler waters. .
Which ocean current flows from the Gulf of Mexico along the eastern coast of the United States toward Europe?
California Current
Humboldt Current
Gulf Stream
Labrador Current
The Gulf Stream is a warm, swift Atlantic Ocean current originating in the Gulf of Mexico. It flows along the U.S. East Coast before crossing toward Europe. It significantly influences climate by transporting heat northward. .
What scale is traditionally used to measure the magnitude of earthquakes?
Mercalli scale
Fujita scale
Richter scale
Beaufort scale
The Richter scale assigns a single number to quantify the energy released by an earthquake. It has largely been replaced by the moment magnitude scale for precision, but Richter magnitude remains well-known. The Mercalli scale measures intensity based on observed effects. .
What term describes the concentration of dissolved salts in water?
Density
Turbidity
Viscosity
Salinity
Salinity measures the amount of dissolved salts, typically expressed in parts per thousand. It affects water density, circulation patterns, and marine life habitats. Ocean salinity averages about 35‰. .
What is the primary driver of tectonic plate movement?
Solar heating of the crust
Lunar tidal forces
Convection currents in the mantle
Earth's magnetic field
Mantle convection, caused by heat from Earth's core, generates currents that push and pull tectonic plates. This movement leads to continental drift, earthquakes, and volcanic activity. Solar heating and tides have negligible impact. .
Which type of rock forms when lava cools rapidly at Earth's surface?
Basalt
Granite
Gabbro
Diorite
Basalt is an extrusive igneous rock that forms from the rapid cooling of lava at the surface. Its fine-grained texture contrasts with gabbro, which cools slowly underground. Granite and diorite are also intrusive rocks. .
What is the primary compositional difference between basalt and gabbro?
Silica content
Crystal size
Age of formation
Iron content
Basalt and gabbro have the same chemical composition but differ in crystal size. Basalt cools rapidly at the surface, producing fine grains, while gabbro cools slowly underground, forming coarse crystals. Their mineralogy is otherwise similar. .
Thermohaline circulation in the global oceans is driven by differences in what properties of seawater?
Atmospheric pressure
Sunlight intensity
Wind and tides
Temperature and salinity
Thermohaline circulation, also called the global conveyor belt, is driven by density gradients in seawater caused by temperature (thermo) and salinity (haline) variations. Cold, salty water sinks and warmer water rises, creating a global current. .
What term describes precipitation resulting when moist air is forced upward by mountain ranges?
Convective precipitation
Frontal precipitation
Cyclonic precipitation
Orographic precipitation
Orographic precipitation occurs when air masses are lifted over a topographic barrier, such as a mountain range. As the air rises, it cools and condenses, forming clouds and precipitation. The leeward side often lies in a rain shadow. .
Which mineral is commonly used as an index mineral to indicate high-grade metamorphism?
Chlorite
Talc
Kaolinite
Garnet
Garnet is stable only under elevated temperatures and pressures, making it an index mineral for medium- to high-grade metamorphism. Chlorite and talc form at lower grades, while kaolinite is a clay mineral. Identifying garnet indicates specific metamorphic conditions. .
A mesoscale convective system (MCS) is best described as:
A cluster of thunderstorms
A tropical cyclone
A single small storm cell
An isolated lightning storm
An MCS is a large, organized complex of thunderstorms that can span hundreds of kilometers. It often brings heavy rainfall, hail, and strong winds. These systems can last several hours to a day. .
The deepest parts of the world's oceans are found at which feature?
Abyssal plains
Mid-ocean ridges
Deep-sea trenches
Continental shelves
Deep-sea trenches, such as the Mariana Trench, are the deepest oceanic features, reaching depths over 11,000 meters. They form at convergent plate boundaries where one plate subducts beneath another. Abyssal plains are relatively flat and shallower. .
The carbonate compensation depth (CCD) in the ocean is the depth at which:
Calcium carbonate dissolves as fast as it accumulates
Salt begins to precipitate
Organic carbon is buried rapidly
Carbon dioxide is fully consumed
The CCD is the depth below which the rate of CaCO? dissolution exceeds its accumulation, so shells and skeletons dissolve. It typically lies between 4,000 and 5,000 meters. Above the CCD, carbonate sediments can accumulate. .
The critical Rayleigh number for the onset of thermal convection in Earth's mantle is on the order of:
10
10?
10³
10?
Laboratory and theoretical studies show that convection initiates when the Rayleigh number exceeds approximately 10³. This dimensionless number compares buoyancy forces to viscous resistance. In Earth's mantle, higher values ensure vigorous convection. .
The S-wave shadow zone occurs at angular distances from an earthquake epicenter between:
0° - 30°
90° - 110°
30° - 60°
104° - 180°
S-waves cannot travel through the liquid outer core, creating a shadow zone on the Earth's surface from about 104° to 180° from the epicenter. Seismometers in this region record no direct S-waves. The P-wave shadow zone is narrower (104° - 140°). .
Mid-ocean ridge basalt (MORB) differs from ocean island basalt (OIB) in that MORB typically has:
Significantly higher MgO content
Greater alkali metal content
Lower concentrations of incompatible elements
Higher concentrations of incompatible elements
MORB originates from a depleted upper mantle source and is relatively low in incompatible elements (e.g., K, Rb). OIB derives from deeper, enriched mantle plumes and is richer in those elements. Both are tholeiitic basalts but differ in trace chemistry. .
