Explanation:

Question 8

Greenhouse gases trap heat in the Earth's atmosphere. As their concentration increases, more heat is trapped, leading to a rise in global temperatures. So the correct option is the one where temperatures increase.

The Earth's systems (biotic and abiotic) are interconnected. A change in one component (e.g., deforestation affecting climate and wildlife) can impact multiple other parts. So the correct statement is about everything being connected and a change in one thing affecting many different parts.

• Observation: Involves using senses (sight, hearing, etc.) to study something. So A matches "using your senses to investigate something".
• Gather Evidence: Often includes recording observations (like taking notes, measurements) to collect data. So B matches "Recording observations".
• Experimentation: Is the process of testing a hypothesis (possible explanation) through controlled tests. So C matches "Testing a possible explanation".
• Modeling: Involves creating a visual (or other type) representation of a system or concept. So D matches "creating a visual representation".

Answer:

b. Increase
