Earth Sun Relationship

Front

Latitude Noun

---

[lat-i-tood]

Back

Latitude

---

A geographic coordinate that specifies the north-south position of a point on the Earth's surface, measured in degrees.

---

Example: The image shows how sunlight hits the Earth at different angles, illustrating latitude's effect on sunlight distribution.

Front

Circumference Noun

---

[ser-kuhm-fer-uhns]

Back

Circumference

---

The total distance around the outside of a circle or a spherical object, such as a planet like Earth.

---

Example: Arrows show the circumference of Earth, illustrating the distance around the planet.

Front

Parallel Adjective

---

[par-uh-lel]

Back

Parallel

---

Describes lines, such as lines of latitude or light rays, that are always the same distance apart and never intersect.

---

Example: The image shows parallel lines in geometry and real life, explaining they never intersect and remain equidistant.

Front

Protractor Noun

---

[proh-trak-ter]

Back

Protractor

---

A measuring instrument, typically made of transparent plastic, used for measuring angles in units of degrees.

---

Example: The image shows a protractor with labeled parts, explaining how it measures angles in degrees.

Front

Stadium Noun

---

[stey-dee-uhm]

Back

Stadium

---

An ancient Greek unit of measurement for length, used to measure long distances, such as the one between cities.

---

Example: An ancient Greek stadium used for measuring distances, illustrating the concept of a 'stadium' as a unit of length.

Front

Axis Noun

---

[ak-sis]

Back

Axis

---

An imaginary line passing through the center of a spinning object, around which the object rotates, like Earth's axis.

---

Example: The image shows Earth's axis as a line around which it rotates, dividing day and night.

Front

Rotation Noun

---

[roh-tey-shuhn]

Back

Rotation

---

The action of spinning or turning around a central point or axis, which for Earth causes day and night.

---

Example: Earth's rotation on its axis causes day and night, shown by the illuminated and shadowed areas.

Front

Revolution Noun

---

[rev-uh-loo-shuhn]

Back

Revolution

---

The movement of one celestial object in a curved path or orbit around another, such as Earth's journey around the Sun.

---

Example: Earth's revolution around the Sun is shown with arrows indicating its orbit.

Front

Orbit Noun

---

[awr-bit]

Back

Orbit

---

The curved path that a celestial object, like a planet, follows as it revolves around another object due to gravity.

---

Example: Earth follows a curved path around the Sun, showing its orbit due to gravity.

Front

Hemisphere Noun

---

[hem-i-sfeer]

Back

Hemisphere

---

One half of a sphere, especially one half of the Earth as divided by the equator or a meridian.

---

Example: The image shows Earth's division into two hemispheres, illustrating day and night caused by sunlight exposure.
