Introduction to Landforms
This interactive PowerPoint will give all groups a head start in their
individual topics.
What are the Tectonic Plates? VOCABULARY• Asthenosphere• Inner core • Outer core • Crust • Lithosphere • Mantle • Plate tectonics
The plates are composed of the crust and the uppermost part of the mantle. These two layers are often called the lithosphere because they are both composed of solid rock. The plates are layers of rigid, solid rock. However, as they move, plates interact at their edges or boundaries. These interactions generate earthquakes and volcanoes. There are three basic directions or types of boundary interactions.
WHAT ARE THE TWO LAYERS OF THE EARTH THAT MAKE UP THE TECTONIC PLATES?
Test your understanding!
1A. Upper most mantle and CrustB. Crust and magmaC. Asthenosphere and Lithosphere
How are Mountains made?A mountain is a large landform that stretches above the surrounding land in a limited area, usually in form of a peak. A mountain is usually steeper than a hill and they are formed by the shifting of the tectonic plates or by volcanic eruptions.
Vocabulary• Eruption• Trench• Continent• Magma• Mountain• Diverging• Convection
WHAT TWO NATURAL OCCURRENCES THAT CAN CREATE A MOUNTAIN?
Test your understanding!
2A. Rain and SunshineB. Volcanic eruptions and moveme
nt of the tectonic platesC. Hurricanes and Earthquakes
What is a Canyon?A canyon or gorge is a deep ravine between pairs of cliffs. Canyons are often carved from the landscape by erosive activity from rivers and by wind over geologic large time scales. A canyon may also refer to a rift between two mountain peaks.
Vocabulary• Ravine • Geologic • Canyon• Erosion• Uplift• Weathering• Deposition• Gorge
CavesA cave or cavern is a hollow place in the ground, especially natural underground space. Caves form naturally by the weathering of rock and often extend deep underground. There are many different types of caves. Some are: underwater caves, erosion caves, primary caves, glacier caves.
Vocabulary • Cave • Cavern • Limestone• Glacier• Chamber • Sink holes
WHICH OF THESE IS ONE OF THE DIFFERENT TYPES OF CAVES?
Test your understanding!
4A. Primary caveB. Canyon cavesC. Water caves
VolcanoesA volcano is a rapture on the crust of a planetary mass, such as Earth, which allows hot lava, volcanic ash, and gases to escape from the magma chambers below the surface. Earth's volcanoes occur because the planet's crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in the Earth's mantle. There are also underwater volcanoes.
Vocabulary• Rapture • Lava• Planetary • Volcanic ash• Rigid
How did you do?
Did you do great? Did you not do so well?
Not to worry! This was just an introduction. You will learn everything you need to know about your topic with your group. Then you will learn about the other topic from your
classmates.
