Intro to Earth Science
the branch of Earth science that studies the blanket of air that surrounds Earth
meteorology
The combined number of protons and neutrons
mass number
What is the Mohs Scale used to determine?
Hardness
True or False
Eroded materials are almost always carried uphill.
False, they are always carried downhill
A landslide that occurs on steep slopes in mountainous areas with thick snow
Avalanche
Identifying rocks, studying glacial movements, and interpreting clues to Earth's history are all topics studied
Geology
A tiny particle that has mass and a positive electrical charge
proton
Which type of identify minerals is this when a mineral has perfect break in sheets.
Cleavage
Much of Earth's surface is covered by this.
Sediments
This type of weathering is where rocks and minerals break down into smaller pieces. Only the size and color changes.
Mechanical Weathering
The study of objects beyond Earth's atmosphere
Astronomy
The attraction of two atoms for a shared pair of electrons that holds atoms together
covalent bond
Which type of way to identify minerals is this when minerals break roughly or with unique patterns
Fracture
Rocks that cool slowly and beneath Earth's crust
Intrusive
This type of weathering undergo changes in their composition.
Chemical weathering
The water in Earth's oceans, seas, lakes, rivers, glaciers, and in Earth's atmosphere
Hydrosphere
A substance that cannot be broken down into simpler substances
an element
This is a common way to identify minerals. Geologist use this as a measure of density for accurate identification of a mineral.
Specific gravity
Rocks that cool rapidly and on Earth's surface
Extrusive
What percent of earth's water is salt water.
97%
The application of scientific discoveries
technology
The process of changing from a liquid into a gas
evaporation/vaporization
This type of way to identify a mineral is when a mineral's smudge may not match its external color
Streak
True or False
The porosity of sandstone allows it to hold oil, gas, and water.
True
What is the name of this type of underground water where heated water is discharged from the ground.
Hot springs
