Solstice Vocabulary matching worksheet with definitions for astronomy terms.

Let’s match each vocabulary word with its correct definition.

We have 7 words on the left and 7 definitions on the right. We need to pair them correctly.

—

Step 1: Look at “equinox”
→ This is a time of year when day and night are about equal. The definition that says “The time at which the sun crosses the celestial equator” matches this. That’s the spring or fall equinox.
✔ equinox → The time at which the sun crosses the celestial equator

—

Step 2: “astronomer”
→ An astronomer studies space and stars. So, “An expert or student in astronomy” fits perfectly.
✔ astronomer → An expert or student in astronomy

—

Step 3: “heliocentric”
→ “Helio” means sun. Heliocentric means the sun is at the center. So, “Believing that the sun is the centre of the universe” is correct.
✔ heliocentric → Believing that the sun is the centre of the universe

—

Step 4: “hemisphere”
→ A hemisphere is half of a sphere — like Northern/Southern or Eastern/Western halves of Earth.
✔ hemisphere → Half of the earth - Northern and Southern, or Eastern and Western

—

Step 5: “longitude”
→ Longitude lines run north-south and measure how far east or west you are from the Prime Meridian.
✔ longitude → The distance of a place east or west of the Prime Meridian

—

Step 6: “latitude”
→ Latitude lines run east-west and measure how far north or south you are from the equator.
✔ latitude → The distance of a place north or south of the earth’s equator

—

Step 7: “helix”
→ A helix is a spiral shape, like a spring or DNA strand. “A 3D shape with a curve on a cylindrical surface” describes it well.
✔ helix → A 3D shape with a curve on a cylindrical surface

—

All matches are now complete and checked.
