Friday Starting Line Directions: Enter the classroom quietly, log on to Planbook, and answer the questions appropriately on the Google form. You have 5 minutes to do this. What is the difference between magma and lava? At a subduction (zone), which type of plate sinks? Volcanoes that form far away from a plate boundary are called what? Name a liquid with a high viscosity. Hint: What does viscosity mean?

Friday Starting Line Directions: Enter the classroom quietly, log on to Planbook, and answer the questions appropriately on the Google form. You have 5 minutes to do this. Magma = under the Earth; Lava = on top of the Earth Oceanic plate Hot Spots Syrup, molasses, honey, etc.

Announcements Homework Turn-In: None We are starting our Volcano Unit! Vocabulary is due tomorrow! We are starting our Volcano Unit! We learned our vocabulary on Monday, but we are not having a special Vocabulary Quiz for this Unit. We are having a TEST next Tuesday!! There WILL be vocabulary on this Test!

Earth and Space Science Unit 5 : Earthquakes and Volcanoes I can describe the anatomy of a volcano, the difference between magma and lava, and where volcanoes form.

Notebook Notes Directions: In your document, write the following information in this order on the LEFT SIDE. (Your Name) Mr. Swisher Earth and Space Science _____ (Period) 11/18/2016

Notebook Notes Directions: In your document, write the following information in this order in the CENTER in BOLD. 13.1 Volcanoes and Plate Tectonics

Volcanoes Volcano: A vent that carries molten (hot, liquid) rock and gases from below the Earth to its surface during an eruption.

Parts of a Volcano Crater Gas & Ash Cloud Lava Flow Sideways Vent Dike Lava & Ash Layers Central Vent Magma Chamber

Parts of a Volcano Magma Chamber: Stores magma under the volcano Dike: Cooled magma coming off the magma chamber or central vent Central Vent: Long tube that connect the magma chamber to the Earth’s surface Contains an opening through which magma leaves Connects to sideways vent Crater: Bowl-shaped area around the central vent Lava Flow: Lava that leaves the volcano and moves down the side Creates layers of lava and ash Gas & Ash Cloud: Pyroclastic material that leaves the volcano during an eruption

Lava vs. Magma Lava = ON the surface of the Earth Magma = UNDER the surface of the Earth Forms from melted crust and mantle

How Magma Forms Magma forms when… Temperature increases Pressure decreases Water or other liquids are added to the rock

Where Volcanoes Form Subduction Zones: An oceanic plate moves under a continental plate Magma forms when water is added to the rock Hot Spots: Volcanoes are NOT near a plate boundary Magma forms when the pressure decreases in the mantle plume Mid-ocean Ridges: Two plates move apart

Where Volcanoes Form

Volcano Vocabulary Words Island Arc: A string of volcanoes formed on the continental plate by a subduction zone. Pacific Ring of Fire: A major earthquake and volcanic zone in the Pacific Ocean; formed by the subduction of tectonic plates

Intrusive Activity vs. Pluton Whenever a volcano erupts, the magma invades or intrudes and takes over the current rock. In a pluton, the magma cooled and hardened before it reached the surface of the Earth.

Pacific Ring of Fire Lab Directions Work on plotting the volcanoes around the Pacific Ring of Fire. Please follow all directions in the lab. Then, answer the questions on the back of the lab worksheet. You will need to do some reading to get the answers. When you finish, you may turn the lab worksheet in to the class tray and work on your Crosswords from yesterday. Due Date: Monday, 11/21!
