Eclipses & Tides: Alignment with Different Mechanisms — Drills · Grade 6 Science

Chapter: Earth, Moon, Sun & Space Models

What these drills covers

By the end of Eclipses & Tides: Alignment with Different Mechanisms you should be able to:

4 questions, multiple choice and written answer, each with a worked explanation.

Vocabulary used: tidal range, eclipse, evidence, system boundary, uncertainty.

Problem 1

Recall the first key distinction: which statement is accurate?
  1. Ocean tides are caused by the Moon’s shadow.
  2. Every new or full phase must produce an eclipse.
  3. tidal range: The difference between high and low water levels using the same reference.
  4. A sample with missing measurements has proved those values are zero.
Answer and explanation

tidal range: The difference between high and low water levels using the same reference.

The difference between high and low water levels using the same reference.

Problem 2

Recall the second key distinction: which statement is accurate?
  1. Repeating any method makes every causal claim true.
  2. Ocean tides are caused by the Moon’s shadow.
  3. Every new or full phase must produce an eclipse.
  4. eclipse: An alignment event in which one body blocks light or another enters a shadow.
Answer and explanation

eclipse: An alignment event in which one body blocks light or another enters a shadow.

An alignment event in which one body blocks light or another enters a shadow.

Problem 3

Without opening guidance: Why is the simple drawing insufficient for local water levels?
Answer and explanation

Local ocean shape, depth, movement, and timing affect the response, so a global sketch does not supply a safe local schedule.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.

Problem 4

Without opening guidance: Does spring tide refer only to springtime?
Answer and explanation

No. The term describes the alignment-related larger tidal range, occurring through the phase cycle rather than one season.

Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
