What is the Big Bang Theory?
A guess as to how the Universe was created
Two plates moving away from each other
How can water cause erosion?
Water takes rocks/sediment and moves it somewhere else
How do air masses take on different temperature and humidity characteristics?
It depends on where it is
What force is responsible for stars creating more elements through nuclear fusion?
Gravity
How old is Earth?
4.5 billion years old
How does coastal erosion shape the earth’s surface?
By physically changing the coast/moving the rocks somewhere else
Explain fully why warm air rises.
Density! It is less dense than the surrounding air
explain or draw what perihelion and aphelion are
Perihelion is the closest point in an orbit
Aphelion is the farthest point in an orbit
What is the density of oceanic crust?
3.0 g/cm3
What is the hydrologic cycle?
the water cycle!
Air circulates in a (counterclockwise/clockwise) direction around a low pressure in the southern hemisphere.
clockwise
Describe the magnitude of the forces of gravity and nuclear fusion when a star is turning into a white dwarf.
Gravity is stronger and nuclear fusion is weaker
Name at lease one of the geologic landforms and/or events form at each plate boundary.
Divergent:
Convergent:
Transform:
Divergent: earthquakes, volcanoes
Convergent: earthquakes, volcanoes, trenches
Transform: earthquakes
How is matter cycled within the mantle?
Convection
How does obliquity change Earth's climate?
More tilt = more intense radiation
Less tilt = less intense radiation
List and/or explain Kepler's 3 laws
1st law: Planets move in elliptical orbits
2nd law: The closer an object is, the faster it travels and covers more area in the same amount of time as it does at aphelion.
3rd law: The farther an object is, the longer it takes to revolve around the sun
How old is a sample if there is 25% Uranium-238 left in the original sample?
about 9 billion years old
What is one example of land features created by constructive processes?
Mountains, volcanoes, islands, deposition
What is the coevolution of earth’s systems and life on Earth?
As Earth was evolving (plants producing oxygen) which causes life to form on Earth
