Show Answer Key & Explanations Step-by-step solution for: Environment - Definitions - ESL worksheet by paula_esl
Let’s work through this step by step.

This worksheet has two parts:

Part A: Match the words/phrases (1–17) to the pictures on the left and right.
Part B: Match the definitions (1–17) to the same list of words/phrases from Part A.

Since we don’t have the actual images to match visually, we’ll focus on Part B, which is purely text-based — matching definitions to the correct terms from the list in Part A.

We’ll go one definition at a time and find the best matching term from the 17 options.
