Why There Are Seasons
What Causes Seasons?
The tilt of Earth's axis and its orbit around the sun.
What layers make up the Earth?
Crust, mantle, outer core, and inner core.
What is erosion?
The process by which soil and rock are removed from the Earth's surface.
What causes the seasons?
C. Earth's tilt relative to its orbit around the sun
What is the tilt of Earth's axis?
Approximately 23.5 degrees.
What is the composition of the crust?
The crust is made of solid rock and minerals.
How does weathering differ from erosion?
Weathering breaks down rocks without movement, while erosion involves movement.
Which best describes Earth's mantle?
A. It is made up of rock so hot that it flows
How do day length and seasons relate?
Longer days occur in summer, shorter days in winter.
What is the mantle?
The mantle is a thick layer of semi-solid rock between the crust and outer core.
What are tectonic plates?
Large sections of Earth's lithosphere that move and interact at their boundaries.
How does plate movement create mountains?
B. When two plates push against each other, the pressure makes the crust bend to form mountains
How does distance from the sun affect seasons?
Distance does not significantly affect seasons; the tilt is more important.
What is the outter core made of?
The outer core is liquid and composed mainly of iron and nickel.
What causes earthquakes?
The movement of tectonic plates along faults.
How does erosion shape mountains?
B. It removes material from mountains, changing their shapes
Why are summers warmer than winters?
The sun's rays hit Earth more directly during summer.
What is the inner core made of?
The inner core is solid and made mostly of iron and nickel.
What role do volcanoes play in shaping the land?
Volcanoes create new landforms by erupting and depositing lava and ash
As one side of Earth turns away from the sun,
C. The sun appears to set on that side of Earth.
