Define tectonic plates.
Large sections of Earth’s lithosphere that move and interact with each other.
What are the three types of plate boundaries?
Divergent, convergent, and transform boundaries.
True or false: Convergent boundaries create mountains.
TRUE These boundaries occur when plates collide, often forming mountain ranges.
Fill in the blank: The Coriolis effect causes moving air to turn ______.
Left in the Southern Hemisphere and right in the Northern Hemisphere.
What is the Foucault pendulum used to demonstrate?
The rotation of the Earth.
Define rotation.
The spinning of Earth on its axis, taking approximately 24 hours.
Define revolution.
The orbit of Earth around the Sun, taking about 365.25 days.
True or false: Seasons are caused by Earth’s rotation.
FALSE Seasons are caused by the tilt of Earth’s axis during its revolution around the Sun.
What is the primary cause of the Coriolis effect?
The rotation of the Earth affecting the movement of air and water.
Fill in the blank: The Earth’s tilt is approximately ______ degrees.
23.5 degrees.
What happens at divergent boundaries?
Tectonic plates move apart, creating new crust.
True or false: The Foucault pendulum swings in a constant direction.
TRUE The pendulum’s plane of swing appears to rotate due to Earth’s rotation.
What is the effect of plate tectonics on Earth’s surface?
It shapes landscapes, causes earthquakes, and forms volcanoes.
Fill in the blank: Summer occurs in the Northern Hemisphere when it is tilted ______ the Sun.
Towards.
Define transform boundaries.
Places where tectonic plates slide past each other horizontally.
What is the main reason for seasonal changes?
The tilt of Earth’s axis relative to its orbit around the Sun.
True or false: Earth’s rotation affects the length of a day.
TRUE A full rotation defines a 24-hour day.
What geological feature is formed at convergent boundaries?
Mountains, trenches, or volcanic arcs.
Fill in the blank: The Coriolis effect influences ocean ______.
Currents.
Define seasons.
The four divisions of the year caused by Earth’s axial tilt and orbit.
What is the impact of tectonic plate movement?
It can lead to earthquakes, volcanic activity, and mountain building.
True or false: Earth’s revolution affects climate.
TRUE The distance from the Sun changes with revolution, influencing seasonal climate.
What is a subduction zone?
A region where one tectonic plate moves under another, often causing earthquakes.
Fill in the blank: The Coriolis effect is strongest at the ______.
Poles.
