How does Earth’s position relative to the Sun cause the four seasons?


a. Earth orbits the Sun once a year and is in a different position with respect to the Sun every three months, resulting in four seasons.


b. The tilt of Earth’s axis with respect to its orbit changes back and forth approximately 46 degrees every six months, resulting in four seasons.


c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.

PLEASE HELP!!!!!! 100 POINTS!! Lab: Absorption and Radiation by Land and Water
Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
The lab report is composed of three sections:
Section I: Experimental Overview
o Provide background information.
o Include the hypothesis.
o Summarize the procedure.

Section II: Data and Analysis
o Include graphs to display trends in the data.
o Identify trends in the data.

Section III: Conclusions
o Identify if the hypothesis was supported or refuted.
o Provide logical reasoning based on data.
o Explain how the experiment could be improved.

To help you write your lab report, you will first answer the eight questions listed below based on the experiment that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn in to your teacher.
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.
Questions

Section I: Experimental Overview
1. What is the purpose of the lab?












2. What is your hypothesis for this experiment?
















3. What methods are you using to test this hypothesis?
Outline the steps of the procedure in full sentences.











Section II: Data and Analysis
4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following items:
a. An appropriate title
b. Appropriate labels for each axis
c. An appropriate scale for each axis
d. The correct units for the data

Complete a rough sketch of each graph.
































5. What do the data in your graphs tell you?
Explain in one or two sentences what trend is shown in each of your graphs.





Section III: Conclusions
6. What do the data tell you about your hypothesis?
State how your hypothesis is either supported OR refuted by the data.









7. How do the data support your claim above?
Explain your statement above. Be sure to refer to specific pieces of data from your experiment that support your argument.












8. If you could repeat the experiment and make it better, what would you do differently and why?
There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.

Plz plz plz help What processes allow continents to change location over time?
Group of answer choices

As the gravitational pull of the sun and moon fluctuate the continents are pushed or pulled in different directions which results in the movement of continents.

Plates are floating and sliding on the asthenosphere. After millions of years the plate movement allows continents to move.

Since the Earth is mostly water, plates can easily float to new locations.
