Shape & Rotation
What are the poles?
The two points of Earth where the axis of rotation emerges
Can the Earth be divided into a rectangular grid? Why or why not?
No, since the Earth’s surface is curved
What is the mercator projection?
A map projection with horizontal parallels and vertical meridians.
Which is the importance of the earth’s rotation on its axis?
Creates the alternation between day and night, and change of seasons
Is our global time system oriented to the sun?
Yes
How does the moon alter ocean surface?
Through gravitaional pull
What forms the geographical grid?
Parallels and meridians
What is the error that occurs in the mercator projection?
Mercator’s make the shortest distance between two points seem much longer than the compass line joining them.
Differenciate the perihelion and the aphelion
Perihelion:point in its orbit at which the earth is nearest to the sun
Aphelion: farthest away from the sun
How can we know, without using a watch, when it is midday?
The sun is located at its highest point in the sky.
How do plants react to the rotation?
Make photosynthesis during the day and uses the energy at night
How many cartographic projections are?
5
What is the Goode Projection? What is it for?
Equal- area map projection often used to display information such as climate or soil type.
By which factor is determined the moon’s position?
The position of the moon in its orbit around the earth
Why does the standard time exist?
It prevents worldwide chaos.
Name one of the reasons why it is known that the Earth’s shape is not strictly spherical.
The force of the rotation of the Earth causes it to bulge at the Equator and flatten at the poles.
What is a meridian? What identifies it?
North- south line on the Earth’s surface, connecting the poles. Identified by longitude.
What is a Polar Projection?
A map projection centered on Earth’s North or South Pole.
What is the main cause of the seasons?
The tilt of the Earth in relation to the Sun
Which is the distance (in degrees) between world time zones?
15°
In spite of the Earth not being spherical, it is not flat either. Name one empirical reason to support this fact.
The Sun rises on the East and sets on the West.
What are the different types of Earth projections?
What is scale fraction?
It is a ratio that tell us how to convert between the distances drawn on our map and true Earth’s distances.
How does a solar eclipse happens?
Occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth
The international date line passes exactly through one country. Which is this?
Fiji
