Geoscience Final!!🌎🌒💫☀️🎇

3. Which of the following is a TRUE statement concerning mass wasting? – It is the large movement of rock, soil, and debris downward due to gravity. (A)
maximum intensity usually occurs near the… – epicenter
Geology – The scientific study of the origin, history, and structure of the earth.
Slope stability – movement occur when the downward pull of gravity overcomes the force resisting it. Type of shearing stress. Friction counteracts the shearing stress.
Analyze the map and select the proper response for missing term or phrase for number 3. – Gravity
Types of Seismic Waves – Body Waves (move along interior) and Surface Waves (move along the surface)
Mineral that is harder than quartz – Corundum
neap tide – time of smallest variation between high and low tides. Occurs when earth, moon and sun align at right angles. Alternate with spring tides
Other ways of figuring out ages – Growth rings in trees and shells; Rhythmic layers in sediment and ice; Magnetostratigraphy – magnetic layers in strata
principle of superposition – in an undeformed sequence of layered rocks: each bed is older than the one above and younger than the one below
fault creep – gradual movement along a fault that occurs in the absence of an earthquake
Wave Properties: – *Wavelength* can be measured as the distance between crests OR from trough to trough.

*Frequency* is the number of waves that pass the observer each second

*Amplitude* is the height of the wave. It indicates the amount of energy in the wave

trace fossil – any evidence other than body parts that an organism once existed
A discordant, two-dimensional plutonic structure that cuts across layers of other rocks – Dike
ash: – fine, glassy fragments less than 2mm. Carried by the wind.
Tycho Brache
-Contributions
-Tried to disprove
-Accuracy – Built an observatory and "pointers" instead of telescopes
Tried to disprove Copernican theory
Precise observations but not accurate
Worked on stellar parallax, calculating how far they shifted
Types of Seismic Waves – Body Waves (move along interior) and Surface Waves (move along the surface)
Squall Line Thunderstorm – • A line of thunderstorms
• Ahead or along a cold front
• Hail, heavy rain, frequent lightning, strong straight line winds
Ice Tongue – long and narrow sheet of ice projecting out from the coastline
Capillary Fringe – In between the saturated and unsaturated zones
climate – aggregate weather conditions, climate data cannot predict the weather
