What are the 3 types of plate boundaries?
convergent, divergent, transform
What kind of weather front has alternating half circles and triangles and happens when two front meet and neither is moving?
stationary front
Cold
Warm
Stationary
What causes seasons?
The tilt of the earth and revolution around the sun
What causes day and night?
Rotation of the earth on its axis
A landform on Earth's surface when 2 continental plates collide/converge __________________________.
mountains
What type of weather would you get with High Pressure air?
Happy Weather (sun, clear skies, little wind)
Sing the Plate Boundaries Song
Convergent is colliding
Divergent is Dividing
Transform is sliding
Why do the Northern and Southern Hemisphere have different seasons at the same time?
The 23.5 degree tilt of the axis- part is getting direct sunlight and the other is getting indirect sunlight
What would happen if the earth rotated faster?
The length of the day would be shorter
_______________________ occur when a transform boundary along Earth's crust slides and gets stuck
Earthquakes
What are hurricanes called in other regions of the world? 2 answers
tropical cyclones and typhoons
What type of air is associated with tropical cyclones and typhoons?
What causes tides?
the gravitational pull of the moon
How long does it take the Earth to revolve around the Sun?
365.25 days
Scientists have developed a theory called ___________ _______________ to explain how forces deep within Earth can cause seafloors to spread and continents to move.
plate tectonics
What do you need for hurricanes to form?
warm water, warm temps., low pressure
The theory of continental drift states that all continents were once connected on a single landmass called ____________________ and slowly drifted apart.
Pangea
At which phases would the force of gravity be stronger causing Spring Tides?
Full and New Moon
Why do we have different seasons in the North and South Hemisphere?
The Earth's tilt on it's makes the sun hit the hemispheres unequally
Tectonic plates under Africa used to be closer to the chilly South Polar Regions. Which continental drift evidence explains this?
Glacier marks
Ocean currents affect weather patterns by
distributing the uneven heat produced by the sun
newer crust in the center and older pushed off to the edges
Explain what position you would find summer in N. Hemi and how you know?
position A because it is facing toward the sun and receiving direct sunlight.
Maps of Continents fitting like a puzzle, Matching Fossils on different continents, and evidence of glacier marks are evidence of what?
Continental Drift (Pangea broke and continents moving over time)
