Rocks and minerals
According to the reference table, this mineral is metallic and is easily distinguished because it has a metallic luster, a hardness of 2.5, and a distinct gray streak.
Galena
This process involves the breaking down or dissolving of rocks and minerals on Earth's surface, but not moving them.
Weathering
This is the universal first stage in the life cycle of every single star in the universe.
Nebula
This vital process occurs when deep, cold, nutrient-rich water rises to the surface, fueling massive blooms of phytoplankton and creating rich fishing grounds.
Upwelling
When light appears to shift towards the red end of the electromagnetic spectrum because an object is moving away from the spectator.
Red Shift
This mineral is unique on the chart because it has a salty taste, cubic cleavage, and is used to season food.
Halite
Unlike weathering, this process actually transports the loosened rock particles and soil from one place to another via wind, water, or ice.
Erosion
This single, fundamental characteristic is the number one factor that determines the exact life cycle path a star will take.
Mass
This major climate phenomenon occurs when trade winds weaken, allowing warm water to push east toward South America, disrupting global weather patterns and stopping local upwelling.
El Niño
A method to date rocks or artifacts based on their radioactive element content
Radioactive Dating
This coarse-grained, intrusive igneous rock has a felsic composition and is commonly used to make kitchen countertops.
Granite
Acid rain reacting with limestone to create underground caves is a prime example of this specific type of weathering.
Chemical Weathering
The X and Y-axes of the H-R Diagram give us five key pieces of data. Name at least three of them.
Luminosity, Temperature, Color, Spectral Class, and Size/Mass?
A natural climate pattern where the trade winds blowing across the equator in the Pacific Ocean become incredibly strong. These super-charged winds push warm surface water away from South America toward Asia.
La Niña
The force of attraction between any objects with mass. The more mass an object has the greater the attraction between the two objects is
Gravity
To transform a sedimentary or igneous rock into a metamorphic rock, it must be subjected to these two forces without melting.
Heat and pressure
These massive, slow-moving rivers of ice are incredibly powerful agents of erosion, carving out distinct U-shaped valleys as they advance.
Glaciers
Using the words eccentric, orbit, Sun, and heat, explain why Comet Borrelly shoots out gas and dust only every few years.
The comet has a highly eccentric orbit. When its path brings it close to the Sun, the solar heat causes its icy material to turn into gas and dust
During normal years, these persistent global winds blow from East to West across the equator, piling up warm water in the Western Pacific near Asia.
trade winds
The first photosynthetic organisms that were responsible for producing a majority of our Atmospheres oxygen
Cyanobacteria/Stromatolites
The rock cycle shows that magma must undergo this specific physical process to become an igneous rock.
solidification (or cooling/crystallization)
This is the general term for the ongoing decrease in the pH of Earth's oceans, caused by the uptake of anthropogenic carbon dioxide.
Ocean acidification
This catastrophic event occurs immediately after a massive star builds up iron in its core and fusion completely stops.
Supernova
This phenomenon, caused by Earth's rotation, deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating our global trade winds.
Coriolis effect
What are 3 pieces of evidence that support the Big Bang Theory.
1.Red shift
2.Cosmic Microwave Background Radiation (CMBR).
3. Light Elements - Nucleosynthesis
