Sedimentary rock Middle Triassic marginal marine sequence of siltstones (below) and limestones (above), Virgin Formation, southwestern Utah, USA Genetic classification Based on the processes responsible for their formation, sedimentary rocks can be subdivided into four groups: clastic sedimentary rocks, biochemical (or biogenic) sedimentary rocks, chemical sedimentary rocks and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes. Clastic sedimentary rocks Main article: Clastic rock Clastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest. Conglomerates and breccias Sandstones Composition of framework grains The relative abundance of sand-sized framework grains determines the first word in a sandstone name. Abundance of muddy matrix between sand grains Mudrocks Biochemical sedimentary rocks
ippex online - main The Language of Maps Kids Should Know Though in the age of iPhones and GPSs we seem to be losing paper maps, I still love exploring maps, and believe kids need to learn map skills, and develop their geography awareness. Because of this I have many activities on Kid World Citizen to help parents and teachers teach children about maps. Kids not only can learn to read them, but to recognize their components and build their own maps. I was recently asked for a list of vocabulary or concepts of maps kids should learn. Here are the geographic terms- and their definitions- that I think are important for kids to be able to identify. Thank you creative commons for the images I was able to adapt! Want the materials for this lesson? Buy a full lesson plan about Map Vocabulary at the Kid World Citizen store at Teachers Pay Teachers! The Map Vocabulary Lesson Plan features three activities that help students develop a strong foundation in the geographic terminology associated with maps. Absolute Location vs Relative Location: Axis Equator
Capture List of tectonic plates Plate tectonics map from NASA Current plates Geologists generally agree that the following tectonic plates currently exist on the Earth's surface with roughly definable boundaries. Tectonic plates are sometimes subdivided into three fairly arbitrary categories: major (or primary) plates, minor (or secondary) plates, and microplates (or tertiary plates). Major plates These seven plates comprise the bulk of the continents and the Pacific Ocean. Pacific Plate – 103,300,000 km2North American Plate – 75,900,000 km2Eurasian Plate – 67,800,000 km2African Plate – 61,300,000 km2Antarctic Plate – 60,900,000 km2Indo-Australian Plate – 58,000,000 km2 Often considered two plates: Australian Plate – 47,000,000 km2Indian Plate – 11,900,000 km2South American Plate – 43,600,000 km2 Minor plates These smaller plates are often not shown on major plate maps, as the majority do not comprise significant land area.

Penrod - Sixth Grade Science pHet-analysis-sheet.docx There are three important pieces to your child's education: student, parent, teacher, with the STUDENT being the most important piece of this puzzle. When the three pieces work together as a team, the student may attain the best education possible. Ultimately, the responsibility of this education falls on the STUDENT'S shoulders. They must have a good attitude, and to ensure their success as a student and as they enter into a life after school. I pledge to "BE A TIGER" and do the best I can to help your child ensure a successful future, and I look forward to working with you as a team. I provide opportunities throughout the course of the nine weeks for you to take part in your child's education. PLEASE, if you have any questions please feel free to contact me at the Junior High at 947-4527. grade-6-standards.pdf
what's shakin An earthquake is a sudden release of stored energy. Earthquakes occur when slow but powerful tectonic forces cause stress to build up in the Earth’s crust. When the stresses get large enough, slippage is triggered along fractures in the rock known as faults. The sudden slipping motion along a fault causes vibrations known as seismic waves to form and travel away from the zone of slippage. Several meters of slip along a large fault causes a major earthquake; a few centimeters of slip on a small fault (perhaps the size of a soccer field) would cause a small earthquake. Larger earthquakes cause stronger seismic waves. Seismic waves that travel through the rocks of the Earth’s crust are similar to the ripples that spread across the surface of a pond after a rock splashes into the still water. Seismographs are sensitive instruments that record the vibrations of passing seismic waves.
Earth Systems - 6th Grade Science Earth Systems, Structures and Processes6.E.2 Understand the structure of the earth and how interactions of constructive and destructive forces have resulted in changes in the surface of the Earth over time and the effects of the lithosphere on humans. 6.E.2.1 Summarize the structure of the earth, including the layers, the mantle and core based on the relative position, composition and density. 6.E.2.2 Explain how crustal plates and ocean basins are formed, move and interact using earthquakes, heat flow and volcanoes to reflect forces within the earth. 6.E.2.3 Explain how the formation of soil is related to the parent rock type and the environment in which it develops. 6.E.2.4 Conclude that the good health of humans requires: monitoring the lithosphere, maintaining soil quality and stewardship. *** Please wait while the videos load. *** 6.E.2.1 - Layers of the Earth 6.E.2.3 - Geology Kitchen #1 - What is a Mineral? 6.E.2.3 - Geology Kitchen #2 - Identifying Minerals
Smithsonian Science Education Center Where is Earth's water? The USGS Water Science School "Water, Water, Everywhere...."You've heard the phrase, and for water, it really is true. Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground. Below are two representations of where Earth's water resides. The globe image represents how much actual water exists, compared to the total size of the Earth. Distribution of Earth's Water In the first bar, notice how only 2.5% of Earth's water is freshwater - the amount needed for life to survive. View a larger version of this image and learn more.
