1. Landscapes

2. What is a landscape?
A landscape is part of the Earth’s surface that can be viewed at one time from one place.

3. let’s identify some landforms
What can you see?

4. chain of mountains
mountain peak
lake

6. clouds
valley
evergreen
river
field

7. plain
volcano
waterfall
hills

8. Bodies of Water
ocean
river
lake
stream

9. a closer look at rivers
definition: A river is a natural watercourse, usually freshwater, flowing towards an
ocean, a lake, a sea, or another river.
In a few cases, a river simply flows into the ground or dries up completely at the end of its
course, and does not reach another body of water.

10. a closer look at rivers
The longest rivers in the world are the Nile in Africa and the Amazon in South America
A river bank is the "edge" of a river
where the land begins.
Rivers meander.
A river meander is the turns that a
river makes when it is flowing
Some flow all year round. Others flow seasonally or during wet years.

12. A brief look at vegetation zones
Scientists divide the Earth’s land into what are called vegetation regions or zones. These areas have distinct types of plants, soil(terreno), and weather patterns.
We will look at the five main zones. Which ones do you already know?

13. Forests
Forests are areas with trees grouped in a way so their leaves, or foliage, shade the ground. Forests can be found just about anywhere trees can grow, from below sea level to high in the mountains.
shade = ombra
to shade = ombreggiare

14. Grasslands
Grasslands are flat and open areas where grasses are the dominant type of vegetation. Grasslands can be found on every continent except Antarctica.
grass = erba

15. Tundra
Tundra is an area where tree growth is difficult because of cold temperatures and short seasons. Vegetation in tundra is limited to a few shrubs, grasses, and mosses
shrub = cespuglio
moss = muschio

16. Desert
Deserts have almost no precipitation, or rainfall. In fact, deserts are specifically defined as areas with an average annual precipitation of less than 10 inches per year.
Desert soil is often sandy or rocky. Plant life is highly specialized to adapt to these coarse, dry conditions.
sandy = sabbioso

17. Ice sheet
The interesting thing about the ice sheet “vegetation region” is that there really isn’t any vegetation there at all! An ice sheet is a large stretch of glacier ice that covers the land all around it for more than 50,000 square kilometers (20,000 square miles).
Currently, the only ice sheets are in Antarctica and Greenland. Don’t confuse the ice sheets, called polar ice caps, with other ice shelves or glaciers; an ice sheet is much, much bigger.

18. Vegetation Distribution What is a tree line?
The tree line refers to the edge of a habitat at which trees are capable of growing.
