Resumen del Recurso
Pregunta 1
Pregunta
Earth's core...
Respuesta
is under such intense pressure that it's made of Iron
is divided into two parts- lithosphere and asthenosphere
generates Earth's magnetic field
is the thinnest layer
Pregunta 2
Pregunta
Identify the TRUE statement.
Respuesta
The composition of the jovian planets is mainly gas and ice
The sun accounts for almost 50% of the solar system's mass
The only two planets with moons are Earth and Jupiter
Our sun is the only star we know that has planets associated with it
Pregunta 3
Pregunta
Identify the FALSE statement. The big bang...
Respuesta
occurred more than 13 billion years ago
began with all matter and energy concentrated in an infinitesimally small point
theory states that at the instant of explosion, everything had so much thermal energy even the smallest atomic pieces couldn't exist
is the explanation for how our solar system was developed
Pregunta 4
Pregunta
The moho is the boundary between Earth's...
Respuesta
crust and mantle
inner and outer core
mantle and outer core
continental crust and oceanic crust
Pregunta 5
Pregunta
Which of Earth's layers accounts for the most volume of Earth?
Respuesta
The mantle
The lithosphere
The inner core
The crust
Pregunta 6
Pregunta
The geothermal gradient...
Respuesta
Refers to the rate of change in temperature with depth in the Earth
Increases as you go into the Earth
Averages about 5 degrees celcius per km in the upper crust
States that temperatures near the mantle-core boundary may exceed the temperature of the sun
Pregunta 7
Pregunta
Identify the False statement. The nuclear theory states that...
Respuesta
as the universe cooled, atoms and molecules accumulated in patchy clouds of gas called nebulae
nebulae condensed and heated to become spinning accretion disks
as density increases due to more gas being crammed into a small space, temperature cools
gravity caused the inward collapse of dense gas to form protostars
Pregunta 8
Pregunta
Use the figure to describe the relationship between air pressure and altitude
Respuesta
Air pressure increases linearly with altitude
At the top of mount Everest, air pressure is less than .4 bar
Air pressure increases above .6 bar at an altitude less than 7 km
At the altitude that commercial jets fly, air pressure is higher than 1 bar
Pregunta 9
Pregunta
Which of the following statements about the crust is false?
Respuesta
The crust is the top of the mantle that has cooled and hardened
The crust and the upper part of the mantle make up the lithosphere
The thickness of crust can vary from -1 km up to 70 km thick
There are two different types of crust- oceanic and continental
Pregunta 10
Pregunta
The two most common gases of the Earth's atmosphere are...
Respuesta
Carbon Dioxide (CO2) and Oxygen (O2)
Water (H2O) and Oxygen (O2)
Oxygen (O2) and Methane (CH4)
Nitrogen (N2) and Oxygen (O2)
Pregunta 11
Pregunta
Identify the FALSE statement. Differentiation of large planetesmals and protoplanets...
Respuesta
was caused by heat created by transformation of kinetic energy from collisions into thermal energy
was inhibited by the presence of radioactive elements because their decay absorbs heat from their surroundings
began with heating up component materials within their bodies
is the process by which these bodies develop internal layering
Pregunta 12
Pregunta
Which of the following groups of elements makes up the most mass of the Earth?
Respuesta
Silicon, iron, potassium, sodium
Magnesium, iron, carbon dioxide, argon
Nitrogen, oxygen, helium, carbon dioxide
Iron, oxygen, silicon, magnesium
Pregunta 13
Pregunta
The current theory that explains the formation of our moon states that it...
Respuesta
Coalesced from gas and dust in its current place next to Earth
Was a separate small planet before it was captured by Earth's gravity
was formed by the collision of Earth with mars-sized protoplanet
spun off the fast-spinning Earth during early formation of the solar system
Pregunta 14
Pregunta
Identify the TRUE statement.
Respuesta
Igneous rocks form when preexisting rocks undergo changes in heat and pressure
Hot molten rock that cools and hardens produces metamorphic rocks
Sedimentary rocks form when preexisting rock grains are cemented together
Magma is the term for very hot rock that is molten;when it cools and hardens it's called lava
Pregunta 15
Pregunta
Choose the list that accurately shows rock composition decreasing in silica and increasing in magnesium and iron.
Respuesta
Granite, peridotite, basalt
Granite, basalt, peridotite
Peridotite, basalt, granite
Basalt, peridotite, granite
Pregunta 16
Pregunta
Identify the FALSE statement.
Respuesta
The Earth has both magnetic and geographic poles
Earth's magnetic field is dipole
The sun's stellar wind distorts magnetic field into teardrop shape
Region inside the Earth's magnetic shield is the biosphere
