Rocks & Minerals
This determines a minerals, hardness, breakage, and crystal shape
Internal arrangement of atoms
What mineral in limestone causes it to react with acid rain?
Calcite
Why is water warmer at nighttime and cooler during the daytime?
Water has a high specific heat and takes a long time to release energy.
What causes the moon to appear to go through phases when viewing from Earth?
As the moon revolves around Earth, different portions of the illuminated side are visible.
At a convergent boundary, why does oceanic crust subduct underneath continental crust?
Oceanic crust is more dense than continental.
What type of rocks can potentially transform into igneous rocks?
All types of rocks- Sedimentary, Metamorphic, and Igneous
Why are larger sediments deposited first when a stream/ river enters a larger body of water?
When streams/ rivers enter larger bodies of water, stream velocity decreases, therefore larger particles are deposited first.
How did Earth's early atmosphere form?
As a result of the outgassing of water vapor, carbon dioxide, and nitrogen from volcanic eruptions.
During what season is the earth closest to the Sun and are we at perihelion or aphelion at this location?
Winter season and perihelion
What are two geological features created at convergent plate boundaries?
Mountains, volcanoes, volcanic islands, trenches
Rhyolite is an extrusive igneous rock meaning what about its formation?
It cooled quickly at/above earth's surface
An old car exposed to weather conditions will start to rust overtime. This is an example of what type of chemical weathering?
Oxidation
If the air temperature is 50°F and the difference between the wet-bulb and dry-bulb temperature is 0°C, what is the relative humidity?
100%
At what latitude would the star Polaris be overhead and why does it appear that other stars are circulating around Polaris?
90°N and stars appear to circulate Polaris due to Earth's Rotation
A point within the earth where the earthquake originates and seismic waves are released.
The focus
The metamorphic rock gneiss has the highest-grade metamorphism but is not found in contact metamorphism zones. Why?
Gneiss forms from regional metamorphism
As the size of a particle increases, its permeability and infiltration rate ____________________.
Increases
The majority of earth's rain forests are located at the equator. Explain why.
Equator has warm, humid air with low pressure forcing it to rise. This results in great amounts of precipitation.
During what season and what time of day would your shadow be the longest?
During December and at sunrise/ sunset
Compared to oceanic crust, continental crust is (Lighter or Darker) in color and rich in (Silicon or Iron).
Lighter in color and rich in silicon
Igneous rocks like basalt and scoria are mafic in composition. Why do they have a higher density than felsic rocks?
Mafic rocks are rick in Iron and Magnesium which are heavier elements
Is sediment deposited by glaciers sorted or unsorted, and what is one feature left behind that points in the direction the glacier was moving?
Unsorted
Drumlins, striations, finger lakes
What type of pressure is associated with stormy weather and why?
Low pressure because you need warm, humid air to rise and form clouds which bring precipitation and storms.
For a total solar eclipse, what moon phase must occur and what is the name of the darkest part of the shadow?
New Moon and Umbra
The ocean floor having symmetrical magnetic stripes that reflect the Earth's magnetic field reversal is evidence for what?
Sea-floor spreading
