Earth’s Landforms

Start

Standards

SC.6.E.6.2: Recognize that there are a variety of different landforms on Earth's surface such as coastlines, dunes, rivers, mountains, glaciers, deltas, and lakes and relate these landforms as they apply to Florida.

SS.K.G.1.2: Explain that maps and globes help to locate different places and that globes are a model of the Earth.

WL.K12.IH.4.6: Formulate and deliver a presentation on an assigned topic using multimedia resources to support the presentation.

Introduction to Landforms

This interactive PowerPoint will give all groups a head start in their

individual topics.

Landforms of the Earth

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

HOW ARE CANYONS MADE?

Test your understanding!

3A. Change of seasonsB. VolcanoesC. Erosion

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

WHAT ESCAPES FROM VOLCANOES WHEN THEY ERUPT?

Test your understanding!

5A. WaterB. AirC. Lava

YOU ARE CORRECT!

GREAT JOB!!

INCORRECT!

TRY AGAIN

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.
