Gather Your Facts You will need to summarize your team’s findings from your reading and lab so others will understand your portion of this lab You will need to complete a graphic organizer with key elements to your topic

Volcanoes Period 3 Key elements from Volcano Reading: 1 st Finding: Magma is made up melted rock crystals and dissolved gasses. Magma is found deep in the earth’s interior. 2 nd Finding: Dark flat lava plains cover About 17% of the moon’s total surface! They are called Maria from the latin word of seas 3 rd Finding:When magma erupts in the planet’s surface it forms lava. Lab Finding: The more pressure on the syringe caused more lava to flow through the crater. Think of Mason’s armpit example!

Earthquakes Period 3 Key elements from Earthquake Reading: 1 st Finding: Tectonics is the study of how the outer of a planet can shift and break. 2 nd Finding: Fracturing due to extreme temperature changes is common on moons and planets without atmosphere. 3 rd Finding: Fassae is a set of Valleys on Mars formed when the crust is stretched and fractured. Lab Finding: The more twisting and pulling the more cracks. Pushing and pulling also causes mountains and valleys.

Wind Erosion Period 3 Key elements from Wind Erosion Reading: 1 st Finding: Wind is a gas in motion, and it can only exist with planets with atmospheres. 2 nd Finding: A dense atmosphere can erode a surface faster than a thin atmosphere. 3 rd Finding: Winds on Venus in the upper atmosphere can reach up to 350 KPH. In the lower atmosphere the wind speed is around 0 KPH. Lab Finding : During the lab, we learned that particles of sand or dirt fly with the wind. Faster winds would result in more erosion!

Water Erosion Period 3 Key elements from Water Erosion Reading: 1 st Finding: The entire Grand Canyon can fit inside Valles Marineris 2 nd Finding: The channels of Vedra Valles are probably 200 to 300 meters deep 3 rd Finding: Complex stream patterns often look like human nerves. Lab Finding : At the source, there is more erosion. At the mouth, there was delta.

Volcanoes Period 4 Key elements from Volcano Reading: 1 st Finding: Magma is made up of melted rock and crystal and dissolved gasses 2 nd Finding: volcanoes are found on other planets and moons causing them to have shield volcanoes. 3 rd Finding: shield volcanoes are bigger other planets because the crust on other planets is not made of moving plates like Earth’s is Lab Finding : The craters that were made were filled with lava. The lava spewed because of PRESSURE!

Earthquakes Period 4 Key elements from Earthquake Reading: 1 st Finding: Earthquakes occur along faults on Earth 2 nd Finding: Faults occur when parts of the outer layer move past one another 3 rd Finding: Extreme temperature changes from day to night also can cause fractures Lab Finding : The movement of tectonic plates causes earthquakes

Wind Erosion Period 4 Key elements from Wind Erosion Reading: 1 st Finding: Mercury, Moon, asteroids, and many moons of gaseous planets don’t have an atmosphere, which = 0 wind 2 nd Finding: In thinner atmosphere wind must be faster to erode rocks. 3 rd Finding: Wind erosion on Mars swept away particles and left behind boulders. Lab Finding : The lightest material blew away. This left the heavier sand. :

Water Erosion Period 4 Key elements from Water Erosion Reading: 1 st Finding: A stream pattern depends on the slope, topography and the amount of water that flows across the surface. 2 nd Finding: Flowing water erodes rocks and creates canyons, valleys, and stream networks. 3 rd Finding: The source of water can include underwater springs, melting snow or ice caps, or rain. 3 rd Finding: Scientists believe that unlike Earth, other planets crusts are not made of moving plates. This means that other planets volcanoes are many times larger than those on earth. While erosion is a natural process, human activities have increased by times the rate at which erosion is occurring globally. Excessive erosion causes problems such as desertification, decreases in agricultural productivity due to land degradation, sedimentation of waterways, and ecological collapse due to loss of the nutrient rich upper soil layers. Water and wind erosion are now the two primary causes of land degradation; combined, they are responsible for 84% of degraded acreage, making excessive erosion one of the most significant global environmental problems.

Volcanoes Period 5 Key elements from Volcano Reading: 1 st Finding: Magma is made up of melted rock, crystals, and dissolved gases. Thanks for the SOUP example! 2 nd Finding: Dark, flat lava plains cover 17% of the moons total surface. 1/3 of Earth is field of these plains! 3 rd Finding: Scientists believe that unlike Earth, other planets crusts are not made of moving plates. This means that other planets volcanoes are many times larger than those on earth. Earth is unique! Lab Finding : Volcanoes remind us of the water cycle! Think of BARFING!

Earthquakes Period 5 Key elements from Earthquake Reading: 1 st Finding: Tectonics is how the outer layer of a planet can shift and break. 2 nd Finding: When two parallel faults form the block of crusts down with a ridge forming between them. 3 rd Finding: Extreme Temperature changes from day to night also can cause fracturing. Think of an ice cube! Lab Finding : Earthquakes are like glass. Sometimes they pile up

Water Erosion Period 5 Key elements from Wind Erosion Reading: 1 st Finding: The source or that water can invade underwater melting snow, ice caps or rain. 2 nd Finding: The entire grand canyon could fit inside a small section of Valles Mariners. 3 rd Finding: A stream pattern depends on the slope, topography, soil type, and amount of water that flows across the surface. Lab Finding : The steeper the slope the deeper the canyon

Wind Erosion Period 5 Key elements from Water Erosion Reading: 1 st Finding: Wind can only exist on planets with an atmosphere. 2 nd Finding: Wind blows in the direction of a planets rotation. 3 rd Finding: The thicker the atmosphere on a planet the stronger the wind. Lab Finding : Relates to pulling someone across pavement! Think of different weights of people!

Volcanoes Period 8 Key elements from Volcano Reading: 1 st Finding: 2 nd Finding: 3 rd Finding: Lab Finding : A volcano is caused from pressure from underneath the earth. Magma is made up of rock, crystal, and dissolved gasses. A volcano is like a pimple or a balloon Moon’s Maria is made up off volcanic rock similar to the rock on Earth’s ocean floor. Have you ever felt the bottom of the ocean. The largest dome on Venus is 65 km. across. Pothole example

Earthquakes Period 8 Key elements from Earthquake Reading: 1 st Finding: tectonics is the study of how the outer layer of our plant can shift and break. 2 nd Finding: when the outer layer of a planet collide the rock folds. 3 rd Finding: when the two parallel faults form the block of crust between them may drop with a ridge forming between them. Lab Finding : Whenever plates move, they sometimes come together.

Wind Erosion Period 8 Key elements from Wind Erosion Reading: 1 st Finding: 2 nd Finding: 3 rd Finding: Lab Finding : Erosion is caused by wind blowing. Baseball field example! Wind only exists on planets with atmospheres. The moon still has the footprints on it! The thinner the atmosphere, the faster the wind has to blow to impact the surface. The upper atmosphere of Venus is very windy, the winds can be 350 kph.

Water Erosion Period 8 Key elements from Water Erosion Reading: 1 st Finding: the source of water can include underwater springs, melting snow or ice caps, or rain. 2 nd Finding: A stream pattern depends on the slope, topography, soil type, and amount of water that flows across the surface. Upper and Lower Egypt example 3 rd Finding: The Grand Canyon can fit in a small portion of Valles Marinenis. Bracelet example Lab Finding :The steeper the hill that water is flowing down will create a deeper valley!

Attention!!! You will need to copy notes into your notebook and use them when it is time to complete the summary for this unit.
