If you don't have your textbook and need information on renewable and non-renewable resources to answer the questions on your study guide, there are several sources you can refer to:

1. Online resources: The internet provides a wealth of information on various topics, including renewable and non-renewable resources. You can search for reliable websites or educational platforms that provide information on Earth's resources. Make sure to evaluate the credibility and accuracy of the source before using it as a reference.

2. Online libraries or databases: Many libraries provide access to electronic databases and resources that can be accessed remotely with your library membership. These databases often include academic journals, articles, and e-books related to environmental science and renewable/non-renewable resources. Check your local library's website to see if they offer this service.

3. Video lectures or online courses: Online platforms such as YouTube, Khan Academy, or Coursera offer video lectures, tutorials, and courses on various subjects, including environmental science. You may find informative videos or lectures specifically on renewable and non-renewable resources that can help you understand the topic and answer the study guide questions.

4. Online forums or communities: Participating in online forums or communities focused on environmental science or Earth's resources can often provide insights or discussions related to your study guide questions. You can ask specific questions to seek clarification or browse through existing discussions to gather relevant information.

Remember, while these alternative sources can provide information, it is important to cross-reference the information you find and compare it with the content in your textbook whenever possible.
