Earth Science #1
What is heliocentric?
The Earth revolves around the Sun.
The point around which two masses orbit each other is referred as:
The barycenter
What is the source location of where an earthquake originates called?
The Focus
Which star is located closest to the Earth?
The Sun
What is the movement called where Earth's axis slowly and continuously changes direction on a 26,000 year cycle?
Precession
What geographic features form as a result of continental-continental convergent plates?
Mountain Ranges
The correct order of processes involved in the formation of a sedimentary rock from another rock.
What is weathering, erosion, deposition, compaction, cementation
The P-Wave
Which seismic wave of an earthquake travels the fastest.
The process that stars use to create their own energy and light is called:
Nuclear Fusion
Crop rotation (or contour plowing or terracing)
What is a form of farming that conserves soil?
What tide has the Sun, Moon and Earth lined up in a straight line?
The spring tide.
What are Earth's two main movements?
Rotation (spinning on an axis) and revolution (orbiting around the Sun)
Evidence that seafloor is spreading out from both sides of the Mid-Atlantic Ridge.
The age of rocks increase as the distance from the ridge increases.
Why don't you typically see fossils in metamorphic rock?
Fossils are destroyed by the intense heat and pressure.
What is the length of time it takes the Earth to revolve around the Sun?
365.25 days or one year
Name the four layers of Earth
crust, mantle, outer core, inner core
What does 23.5 degrees, the tilt of Earth result in?
This explains the change of seasons
The classification of rocks (sedimentary, igneous, metamorphic)is based on:
The origin of rocks.
What is located at the center of our solar system? a) a black hole b) Earth c) the Moon d) the Sun
What is D: the Sun
What is the path that a celestial body makes.
The orbit
Where are volcanoes located?
At convergent boundaries
The order of the Universe in which we live from biggest to smallest:
What is Universe, galaxies, solar systems, stars, planets, moons
What does the atmosphere (ozone and magnetosphere) protect us from?
Ultra violet rays.
At what point would you find the Earth traveling faster around the Sun?
At aphelion.
Unequal distribution of heat within the Earth (convection currents).
What is the driving force behind the movement of the lithospheric plates?
