Lecture 21: Glaciers and Paleoclimate Read: Chapter 15 Homework Due Thursday Nov
Learning Objectives (LO) Lecture 21: Glaciers and Paleoclimate Read: Chapter 15 Homework due Thursday Nov. 12 What we’ll learn today:! 1. 1. Glaciers and where they occur! 2. 2. Compare depositional and erosional features of glaciers! 3. 3. Earth-Sun orbital parameters, relevance to interglacial periods ! A glacier is a river of ice. Glaciers can range in size from: 100s of m (mountain glaciers) to 100s of km (continental ice sheets) Most glaciers are 1000s to 100,000s of years old! The Snowline is the lowest elevation of a perennial (2 yrs) snow field. Glaciers can only form above the snowline, where snow does not completely melt in the summer. Requirements: Cold temperatures Polar latitudes or high elevations Sufficient snow Flat area for snow to accumulate Permafrost is permanently frozen soil beneath a seasonal active layer that supports plant life Glaciers are made of compressed, recrystallized snow. Snow buildup in the zone of accumulation flows downhill into the zone of wastage. Glacier-Covered Areas Glacier Coverage (km2) No glaciers in Australia! 160,000 glaciers total 47 countries have glaciers 94% of Earth’s ice is in Greenland and Antarctica Mountain Glaciers are Retreating Worldwide The Antarctic Ice Sheet The Greenland Ice Sheet Glaciers flow downhill through ductile (plastic) deformation & by basal sliding. Brittle deformation near the surface makes cracks, or crevasses. Antarctic ice sheet: ductile flow extends into the ocean to form an ice shelf. Wilkins Ice shelf Breakup http://www.youtube.com/watch?v=XUltAHerfpk The Greenland Ice Sheet has fewer and smaller ice shelves. Erosional Features Unique erosional landforms remain after glaciers melt. -

Because topography evolves in concert with water ow during canyon erosion, volumes are similar we suggest that bedrock canyon morphology preserves hydraulic information about canyon-forming floods. In particular, we propose that for a canyon to form with a roughly uniform width by upstream headwall retreat, erosion must occur around the canyon head, but not along the sidewalls, such that canyon width is fl fl Correspondence to: related to ood discharge. We develop a new theory for bedrock canyon formation by mega oods based M. G. A. Lapotre, on flow convergence of large outburst floods toward a horseshoe-shaped waterfall. The model is developed [email protected] for waterfall erosion by rock toppling, a candidate erosion mechanism in well fractured rock, like columnar basalt.

HUNTTING, Supervisor Bulletin No. 45 WASHINGTON'S CHANNELED SCABLAND By .T HARLEN BRETZ l•or sate by Department or Conservation, Olympia, Washington. Price, 50 cents. FOREWORD Most travelers who have driven through eastern Washington have seen a geologic and scenic feature that is unique-nothing like it is to be found anywhere else in the world. This is the Channeled Scab land, a gigantic series of deeply cut channels in the erosion-resistant Columbia River basalt, the rock that covers most of the east-central and southeastern part of the state. Grand Coulee, with its spectac ular Dry Falls, is one of the most widely known features of this ex tensive set of dry channels. Many thousands of travelers must have wondered how this Chan neled Scabland came into being, and many geologists also have speculated as to its origin. Several geologists have published papers outlining their theories of the scabland's origin, but the geologist who has made the most thorough study of the problem and has ex amined the whole area and all the evidence having a bearing on the problem is Dr. J Harlen Bretz.

Three Main Types of Rocks on the Planet and in Oregon Lesson to Grow
Lesson to Grow Three Main Types of Rocks on the Planet and in Oregon Description: This lesson builds on the student readings found Grade Level: 4-10 in Oregon’s Ancient Geology. There are three main types of rocks in the world and all are found here Essential Skills: 3, 9 in Oregon. In this lesson, students learn what the NGSS: 4-ESS2-1, 5-ESS3-1 three main types of rocks are and identify geologic events in our region that could have created these CCSS: RI.4.7, W.4.7, W.4.8 rocks. Social Sciences: 6.11, 6.12, Background: 6.13, 6.14, 7.8., 7.9, 7.10, 7.13, 1) The three student geology readings can be 8.10, HS.14, HS.15 downloaded and printed from the online lesson, Math: MP.5 Oregon’s Ancient Natural History - Time: 2-3 class periods 2) The geologic events described in these readings were capable of forming one or more of the Materials: three types of rocks on the planet - sedimentary, Student reading sheets from metamorphic, or igneous. Oregon’s Ancient Natural History online 3) All rocks on earth are formed as either igneous, sedimentary or metamorphic rocks. The diagram AITC Library Resources: to the right shows how the rocks on earth are changed from one rock type to another. Cycling Back to Nature: Soils Alive This changing of rock types is called the “Rock Cycle”. A copy of this Rock Cycle image The Soul of Soil can be downloaded from the Geology Resources section. More Lessons: Earth as an Apple and Soil Directions: Conservation Note: Prior to this lesson, students should have received a copy of the three-part readings Water Filtering and Soil on Oregon’s Ancient Geology (Columbia Basalts, Missoula Floods, and Fire & Ice) and had Soil Horizons & Below our Feet time to read the material and discuss it with their class. -

Antonia Louisa Brico Was Born in Rotterdam, Holland in 1902. Little Is Known About Her Birth Parents, Johannes and Antonia (Shaaken) Brico, Who Died When She Was Two
Antonia Louisa Brico was born in Rotterdam, Holland in 1902. Little is known about her birth parents, Johannes and Antonia (Shaaken) Brico, who died when she was two. Mr. and Mrs. John Wolthuis (mother’s first name unknown) became her foster parents. In 1907, she emigrated with them to Oakland, California attending school as Wilhelmina Wolthuis, the name they had given her. The Wolthuis home was not a happy environment. Antonia later said: “I’d dream about having an automobile accident in front of someone’s house just so they’d pick me up and be affectionate.” She began piano lessons at age 10 after a doctor suggested this remedy to overcome her nail biting. Soon she was performing at local churches and club meetings. Her original ambition to become a concert pianist changed when she attended a park concert conducted by Paul Steindorff. Rather than limit herself to one instrument, she decided to become a conductor. She later said: “The orchestra to me is the greatest instrument. It is to the musician what the palette is to a painter.” After her high school graduation in 1919, Mr. and Mrs. Wolthuis revealed for the first time that they were not her birth parents. Antonia immediately moved out and had no further contact with them. Antonia enrolled at the University of California at Berkeley. As luck would have it, Paul Steindorff, who had inspired her conducting ambitions, was director of music and, more importantly, director of the San Francisco Opera. Antonia became his assistant. When she received a B.A. with honors in music in 1923, people advised her to teach; a position awaited her, and conducting was no job for a woman. -
