Which of these changes would likely occur if the rate of Earths rotation on its axis increased?
the length of day would be shorter
what evidence shows Earths continents have moved over time (3)
- Maps of coastlines
- locations of fossils
- glaciers in areas that are now warm
tropical cyclone formation requires which three factors?
warm water, moist air, converging wind
what is stationary air pressure
the force exerted by the weight of the air at a specific location, essentially the pressure of the air when it is not moving
ocean currents affect weather patterns by ?
disrupting heat from uneven absorption of solar system
why does autumn start in different months of the year in North America and South America
The tilt of Earths axis 23.5
divergent
a linear feature that occurs when two tectonic plates move apart
convergent
a place on Earth where two or more tectonic plates collide
transform
a place where two tectonic plates slide past each other horizontally, creating a fault line
what causes rift valleys and mid ocean ridges
divergent
What is the position of the sun, moon, and Earth in regards to the greatest effect on ocean tides
The greatest effect on ocean tides occurs when the sun, moon, and Earth are aligned in a straight line
what causes mountain formation and volcanos
convergent boundaries
causes strike slips faults
transform boundaries

true or false
true
convergent boundaries can cause volcanos
true or false
true
When is the force of gravity between the Earth, the moon, and the sun the strongest?
when the area most directly is facing the moon
transform boundaries can cause volcanos
true or false
false
How is the Earth positioned during the summer ?
With its Northern Hemisphere tilted towards the Sun
what evidence best supports the theory that the supercontinent Pangaea broke apart millions of years ago to form todays continents
fossils of the same species found on different continents that are separated by oceans
rotation
the Earth's spinning motion around its axis
rocks that are chemically and geological from the same magma source
plate tectonics
presence of glaciers on the surface are evidence that
tectonic plates were close the the south pole at one time.
How are oceanic crust that is further away from a rift valley is different from oceanic crust that is at the center of a rift valley ?
the crust further away from a rift valley is older than the crust at the center
axis
an imaginary line that runs through the center of the Earth from the North Pole to the South Pole, around which the Earth rotates
revolution
the term used to describe the Earth's orbital motion around the sun:
