"The Rotation of the Earth" PPT courseware

Part One: Learning Objectives of this Lesson

Know the direction, period, axis of rotation and other characteristics of the earth's rotation

Ability to demonstrate the Earth's rotation using a globe

Use facts to explain geographical phenomena such as day and night alternation and time difference caused by the rotation of the earth

I'll participate

observe and operate

Turn your globe so that the rotation matches the direction on the screen

Question 1: Is his demonstration of the Earth's rotation correct?

Question 2: What is the center of the Earth's rotation?

Question 3: What is the rotation of the earth?

The Earth's rotation PPT, part 2: the direction and period of the Earth's rotation

Viewed from above the North Pole, the Earth rotates counterclockwise

Viewed from above Antarctica, the Earth rotates clockwise

The geographical significance of the earth’s rotation (1)

The earth is an opaque sphere. Assuming it is stationary, what are the phenomena on the side of the earth facing the sun and the side facing away from the sun? And what geographical phenomena will occur when the earth rotates?

Because the earth is constantly rotating, day and night alternate. The earth rotates from west to east every 24 hours. Locations in the east see sunlight earlier than locations in the west. The rotation creates the phenomenon of day and night.

1. The earth is an opaque sphere: producing day and night phenomena

2. Earth’s rotation: produces alternation between day and night

The geographical significance of the earth’s rotation (2)

Summary: Due to the rotation of the earth, places with different longitudes have different times, which results in local time differences.

Activity: Ask students to list examples of jet lag problems they have encountered.

Summary: The earth rotates 360 degrees in 24 hours, so every 15 degrees of longitude difference is 1 hour of time difference. "Early in the east and late in the west, add in the east and subtract in the west"

Earth's rotation PPT, part three: extension and improvement

1. What abnormal phenomena would occur if the earth did not rotate?

2. If the earth’s rotation direction is from east to west, what special phenomena will occur?

Fierce Eyes: Look what you are capable of

1. The natural phenomenon caused by the rotation of the earth is ()

A. Diurnal phenomenon B Seasonal change phenomenon

C. The phenomenon of changes in the length of day and night D. The phenomenon of day and night replacement

2. In the same latitude area, a location that is relatively eastward is higher than a location that is more westward ()

A. Saw the sunrise first B. Saw the sunrise later C. The time is later D. The time is the same

3. We see the sun and stars rising in the east and setting in the west every day. This is because ( )

A. The sun and stars revolve around the earth B. The earth rotates from west to east

C. The earth rotates from east to west D. The earth rotates around the sun from west to east

Reference answer: C A B
