Minerals and Rocks
What determines a mineral’s physical properties
The internal arrangement of atoms
What is the main type of physical weathering on Long Island?
Frost action
What is an unconformity?
A gap in the rock record caused by erosion
What is the main source of energy for earths weather?
The sun
What are the characteristics of a low pressure system?
High temperature, wet, rotates counter clockwise and in, less dense, rises up in the atmosphere, cyclones, brings lousy weather
What is the basic chemical unit of silicates
Silicon tetrahedron
Name one factor that affects weathering rates
Climate, particle size, mineral composition, exposure
What is correlation of rocks?
Matching rocks or fossils in different areas
How do you determine the type of energy?
The wave length
What are the characteristics of a high pressure system?
Cold temperature, dry, rotates clockwise and out, more dense, sinks in the atmosphere, anticyclone, brings happy weather
What is the difference between intrusive igneous rocks and extrusive igneous rocks
Intrusive rocks are cooled from magma beneath the Earth
extrusive rocks are cooled from lava above the Earth
What type of soil do we have in New York?
Transported soil
What are the characteristics of a good index fossil
Something that lived for a short period of time over a large area
What are the two main processes of the water cycle?
Evaporation and transpiration
How does a cloud form?
Warm, moist air rises, expands, and cools till it reaches the dewpoint, and starts to condense on condensation nuclei
What are the three types of sedimentary rocks
Plastic, Chrystalline and bio clastic
What are the agents of erosion?
Mass movement, running water, wind, and glaciers
How can you change the length of a half life?
You can never change the length of a half life
What is the difference between climate and weather?
Climate is the average weather conditions in a region over a long period of time
weather is the short term conditions of the atmosphere over a region
Air masses are described in terms of their what
Humidity and temperature
Name one thing used to classify, metamorphic rocks
Texture composition, foliation
What is the driving force of all agents and erosion
Gravity
What is the difference between absolute age and Relative age
Absolute age is the actual age of something
relative age is the age of a fossil or rock compared with others around it
Name a factor that affects climate
Latitude distance from oceans, and other large bodies of water, altitude or elevation, ocean currents, topography/mountains and planetary, wind, and pressure belts
What is a front
An interface between two air masses
