Blue
A continuous creation of matter throughout the universe, maintaining a constant density.
Steady State Theory
A solar system hypothesis proposes that the planets formed from a rotating disk of gas and dust.
Nebular Hypothesis
Which of Earth’s subsystems includes all the solid parts of the planet, such as mountains, rocks, and soil?
Geosphere
What property of a mineral tells how easily it can be scratched?
Hardness
What do we call the natural concentration of a valuable mineral that can be mined for profit?
Ore
How does Earth's distance from the Sun affect its ability to support life?
It allows for liquid water and a stable temperature range.
Marble was once limestone but changed due to heat and pressure. What type of rock is marble now?
Metamorphic
What is the central idea of the Tidal/Capture Hypothesis?
A passing star pulled material from the Sun, which later condensed into planets.
Which metallic mineral is widely used in electrical wires and coins?
Copper
The solid portion of the Earth
Lithosphere
A steps to determines the ore's size, shape, magnetism, and grade distribution throughout the deposits
Modeling
A rock sample contains large interlocking crystals and formed slowly beneath Earth’s surface. How would you classify this rock, and what does its texture indicate about its formation?
Intrusive igneous rocks
When warm ocean water evaporates and fuels a typhoon, which two subsystems are involved and how is energy transferred?
Hydrosphere and Atmosphere
A type of metamorphism that foliated rocks are produced and strong pressure effects
Regional
This theory proposes that the Sun captured a passing object through gravitational pull, which then became the planets.
Capture Theory/Tidal Theory
What evidence best supports the Big Bang Theory as the universe’s origin?
Cosmic microwave background radiation
Which soft, black mineral is a major source of energy when burned?
Coal
What is the first step in mining, where scientists search for areas rich in minerals?
Exploration or Prospecting
When bituminous coal is transformed into the shiny, black, high-rank type of coal.
Anthracite
the breakdown of kerogen into hydrocarbons under increasing heat and pressure
Catagenesis
Why is fossil fuel use a sustainability concern despite its energy efficiency?
It emits greenhouse gases and is non-renewable.
A creation of ore minerals which are concentrated due to their premature recrystallization and separation from magma.
Magmatic processes
Igneous can be Sedimentary with the help of what geologic processes.
Weathering and erosion
The law of conservation of energy states ....
that energy can neither be created nor destroyed; it can only be transformed from one form into another.
A dynamic system made up of interconnected subsystems that continuously interact.
Earth
