Test: Locating Places on Earth - Class 5 MCQ

The equator divides the Earth into the Northern and Southern Hemispheres. It is the primary reference line for latitude and marks 0° latitude.

The equator is the most significant latitude at 0° because it divides the Earth into the Northern and Southern Hemispheres. It serves as the reference point for measuring other latitudes.

There are 181 latitudinal lines, including the equator at 0° and 90 lines each in the Northern and Southern Hemispheres. This grid is essential for mapping locations on Earth.

The Arctic Circle, located at approximately 66.5° North, is significant as it marks the latitude beyond which the sun does not set during the summer solstice. This phenomenon is known as the Midnight Sun.

The latitude at 66.5° South is known as the Antarctic Circle. It marks the boundary in the Southern Hemisphere where, during the summer solstice, the sun remains above the horizon for an extended period.

Latitudes never intersect; they are parallel lines that run east to west. This characteristic allows for consistent measurement of distance north or south of the equator.

When moving 1° east from Greenwich at 12 noon, the time becomes 12:04 p.m. This reflects the 4-minute time difference per degree of longitude, indicating that places to the east are ahead in time.

Countries to the east of the Prime Meridian experience sunrise first because the Earth rotates from west to east. This rotation causes the eastern regions to face the sun before the western regions do.

As one moves toward the poles, the distance between longitudinal lines decreases. This is because meridians converge at the poles, making them closer together than at the equator.

The meridian at 180° longitude is known as the International Date Line. It serves as the demarcation for calendar days, where one day ends and another begins.

The Tropic of Cancer is located at 23.5° North latitude. This line indicates the farthest point north where the sun can be directly overhead at noon during the summer solstice.

The standard meridian for Indian Standard Time (IST) is 82.5°E. This meridian is 5.5 hours ahead of Greenwich Mean Time (GMT), which helps standardize time across India.

Latitudes are referred to as parallels of latitude because they run parallel to each other and to the equator. These imaginary lines help in determining the north-south position on the Earth.

The Tropic of Capricorn is positioned at 23.5° South latitude. It marks the southernmost point where the sun can be directly overhead at noon.

Greenwich Mean Time (GMT) is based on the time at the Prime Meridian (0° longitude). It serves as a reference point for calculating time differences worldwide.

The grid formed by latitudes and longitudes is primarily used to locate places accurately on maps and globes. Each point on the grid corresponds to a specific geographic location.

Meridians meet at the poles, forming lines that extend from the North Pole to the South Pole. This characteristic is essential for understanding Earth's geography.

The Prime Meridian, located at 0° longitude, is crucial as it divides the Earth into the Eastern and Western Hemispheres. It runs through Greenwich, London, and is the starting point for measuring longitude.

The time difference between each degree of longitude is 4 minutes. This is because the Earth rotates 360 degrees in 24 hours, which equates to 15 degrees per hour or 1 degree every 4 minutes.

The North Pole is located at 90° North latitude. This is the northernmost point on Earth, where all longitudinal lines converge.
