Database Searching

Keywords are the main ideas of your topic.

Keep these tips in mind when creating your keywords.

  • "Quotation marks" keep words together when searching for phrases.
    • Example: "plate tectonics," "hydrologic cycle"
  • AND and OR structure your search:
    • AND narrows results (includes all terms)
    • OR expands results (includes synonyms)
  • Truncation (asterisk = shift + 8) searches multiple word variations at once.
    • Example: climat* → climate, climatic, climatology, climates
  • Grow Your Keyword List with words you read in abstracts, article titles, and subject headings

Example Search:
earthquakes AND "Pacific Ring of Fire" AND ("plate tectonics" OR "tectonic plates") 

Note: Always place OR terms in parentheses

The Research Process & AI

Click each button to learn about the research process, how AI can help, and how to think critically when using AI.

Your task: Identify an Earth Science question or issue

How AI can help: Use AI to brainstorm research ideas and generate keywords

Think critically: Have I verified AI's topic suggestions relate to credible Earth Science research areas?

Your task: Understand key concepts and ideas related to your topic

How AI can help: Ask AI for simplified definitions and topic breakdowns

Think critically: Do I understand these concepts well enough to explain them in my own words?

Your task: Gather evidence with peer-reviewed studies, reports, and data

How AI can help: Use AI to suggest synonyms for keywords and related concepts

Think critically: Am I searching library databases for real sources, not relying on AI-generated citations?

Your task: Read resources to support your hypothesis

How AI can help: Use AI to help evaluate data and organize findings from sources you've already read

Think critically: Am I reading and analyzing sources myself, or asking AI to summarize them for me?

Your task: Write your paper and cite all sources used

How AI can help: Use AI for outlining, writing help, and citation formatting tips

Think critically: Are the ideas and arguments in my paper my own, with AI only helping to organize them?

AI Limitations in Research

Fabricated Sources (Hallucinations)

AI may confidently cite sources that don't exist. For example, it might suggest reading 'Subduction Zone Dynamics in the Cascadia Region' by Dr. Sarah Mitchell in the Journal of Tectonic Studies. This sounds credible, but the article and author may be completely invented.

Outdated or Inaccurate Scientific Data

Earth science discoveries happen constantly. AI training data has cutoff dates and may not include recent findings about climate patterns, seismic activity, or volcanic eruptions.

No Access to Library Databases

AI cannot search databases like EBSCOhost or ScienceDirectAlways verify AI-generated information through library databases before using it for your research.

Should I Use AI for This?

Use this list to decide when AI can help with research.


✓ Use AI When:

Brainstorming topics

Get ideas for narrower topics or generate keywords related to your subject.

Understanding concepts

Ask for plain-language explanations of technical terms or complex processes.

Organizing ideas

Create outlines or reorganize notes you've already written.


✗ Don't Use AI When:

Verifying facts or data

AI may provide outdated or fabricated information. Always verify in peer-reviewed sources.

Writing graded work

Content you submit must be your own original work.

Getting citations

AI often invents fake sources. Find real articles through library databases.


When in doubt: Ask yourself, "Am I using AI to learn, or to avoid learning?" If it's the latter, use library resources instead.

Getting to Know APA

APA Formatting Rules

  • Author Names: Last Name, First Initial. (e.g., Smith, J.).
  • Title Formatting: Use Sentence Case (Capitalize First Word & Proper Nouns).
  • Italics: Italicize book and journal titles
  • DOIs & URLs: Always include them. No "Retrieved from" needed.
  • In-Text Citations: (Author, Year) → (Smith, 2023). For quotes: (Smith, 2023, p. 45).
  • Reference Page: Double-space, indent second line of each entry.
  • DOI vs URLs? Check out the APA Style Blog website
