Grade 7 · lesson 1 of 4

Latitude Longitude and Hemispheres

Latitude measures north or south of the equator; longitude measures east or west of the prime meridian.

About 20 minutes, plus any extended practice

Supplied materials

Paper and pencil; drawing or spoken answers are welcome.
Topic notes: North and east: north of the equator and east of the prime meridian. North and west: north of the equator and west of the prime meridian. South and east: south of the equator and east of the prime meridian. South and west: south of the equator and west of the prime meridian.
Original exercise cards: Fictional point is at 20°N, 30°E. / Fictional point is at 20°N, 30°W. / Fictional point is at 20°S, 30°E. / Fictional point is at 20°S, 30°W. / Fictional point is at 45°N, 60°W. / Fictional point is at 45°S, 60°E. / Fictional point is at 45°S, 60°W. / Fictional point is at 45°N, 60°E.

Learn the idea

Latitude measures north or south of the equator; longitude measures east or west of the prime meridian. A coordinate needs both direction and number. The four hemisphere combinations below are exercise locations, not named cities. Coordinates do not by themselves reveal climate, language or government.

North and east: north of the equator and east of the prime meridian. North and west: north of the equator and west of the prime meridian. South and east: south of the equator and east of the prime meridian. South and west: south of the equator and west of the prime meridian.

Find the relevant physical feature or spatial relationship, then compare it with the four place descriptions. These exercise cards are original classroom prompts, not quotations or archival documents. The historical notes describe actual topics; invented situations are explicitly called fictional. A correct match needs a reason from the notes, not just a guessed label.

Read the actual topic notes and identify the facts or rule needed for this question.
Work through the solved analysis, distinguishing observations, interpretations and evidence limits.
Solve the new main case: show the relevant sequence, calculation, mechanism, institutional relationship or source comparison before choosing.
Complete the distinct practice cases and state which further evidence would be needed for a broader claim.

Worked example

See the method in action

Worked analysis: Point A is 20°N,30°E; point B is 20°S,30°E. First, separate the supplied facts and the question each can answer. Then compare the relevant rule, relationship or scope. Their latitude directions differ, but their longitude is the same. The coordinates support a spatial comparison, not a prediction of identical weather or culture. Check both the numerical angle and its N/S or E/W direction.

Helpful tips

Check both the numerical angle and its N/S or E/W direction.
Keep the four distinctions separate: North and east, North and west, South and east, South and west. Use a complete reason rather than copying only a title.

See the answer and explanation

They share latitude and occupy opposite east/west hemispheres.

N is the same latitude direction and angle. W and E identify different longitudes on opposite sides of the prime meridian; coordinates alone do not guarantee climate.

Take it further

Write a short response to a new classroom draft claiming that the worked analysis proves a universal result. Use two distinct supplied facts from this lesson, give a supported conclusion, and identify the extra evidence needed for the draft’s broader claim. Expected reasoning: Their latitude directions differ, but their longitude is the same. The coordinates support a spatial comparison, not a prediction of identical weather or culture. A valid response names the scope and does not invent a quotation, date, measure or achieved result.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

1. Compare the supplied original classroom notes: A — Fictional point is at 45°N, 60°W. B — Fictional point is at 45°S, 60°E. Which interpretation preserves both facts?A concerns north of the equator and west of the prime meridian; B concerns south of the equator and east of the prime meridian.A concerns south of the equator and east of the prime meridian; B concerns north of the equator and west of the prime meridian.Both concern only north of the equator and west of the prime meridian.Both concern only south of the equator and east of the prime meridian.

Need a hint?

Find the defining action, direction, date, institution or resource in each note separately.
Keep the conclusion within the stated examples; do not add a universal ranking or unstated causal result.

2. Read this supplied card: “Fictional point is at 45°S, 60°W.” A writer adds, “This one example proves that every person and society has the same experience.” Which revision keeps what the card supports?Keep the specific supported feature: south of the equator and west of the prime meridian. Do not extend one example to every person or society.The one example proves the same experience for every person and society.Reject the specific evidence completely because it does not describe everyone.Replace the stated feature with “north of the equator and east of the prime meridian”, even though that is a different feature.

3. Original classroom brief combines two notes: Fictional point is at 20°N, 30°E. / Fictional point is at 20°S, 30°E. Its draft wrongly treats them as identical. Which corrected comparison is supported?Both establish only south of the equator and east of the prime meridian.The first concerns north of the equator and east of the prime meridian; the second concerns south of the equator and east of the prime meridian. They are distinct features.The first concerns south of the equator and east of the prime meridian; the second concerns north of the equator and east of the prime meridian.Both establish only north of the equator and east of the prime meridian.
