PRESENTATION OUTLINE
What is the Sunspot Cycle?
-The sunspot cycle is the increasing and decreasing of the number of sunspots on the sun over period of 11 years.
When does a sunspot cycle begin?
-The cycle begins when the number of sunspots on the surface of the sun is very low, but starts to increase.
- This minimum represents the beginning of an eleven year sunspot cycle.

When Does the sunspot cycle end?
-The cycle will end after the solar maximum starts to decrease and go back to a minimum.
-A new cycle will begin after the previous one ended.
-A new cycle will begin after the previous one ended.
How Do We Study Sunspot Cycles?
-Butterfly graphs track the activity of sunspots. The graph's x axis represents time and the y axis on the left is latitude and longitude degrees. On the y axis on the right is the number of sunspots on the surface of the sun.
-The SOHO satellite captures the most images of sunspots and how they move during the cycle.
-By studying sunspots, Galileo learned that the sun rotates.

What Causes the Solar Activity Cycle?
-Magnetic fields rising to the surface and twisting in the sun's atmosphere is the cause of the solar activity cycle.
-One activity that's associated with the solar cycle is solar flares. These flares are associate with magnetic disturbances on the sun's surface, sunspots.

Why should we study the solar cycle?
-By studying the activity of sunspots, scientists can learn about and predict when eruptions like solar flares and CMEs can occur, and how we can protect the earth from the havoc those activities can produce.
How does the solar cycle affect Earth?
-When the cycle is at solar maximum, more solar flares and CMEs can happen, causing damage to satellites.
-There are radiation hazards when the cycle is at solar minimum.
-The cycle can affect Earth's climate change/global temperature.
