This most northern part of the earth is called the North Pole.
The region around it is the North Frigid Zone. There is a South Pole and
a South Frigid Zone as cold as the northern one. You can see where they
are on the diagram.

If we start from here and take a trip south we find it constantly
growing warmer. At last we come to a place where it is extremely warm in
both summer and winter. That region is called the Torrid Zone because
"torrid" means "hot." This hot zone extends right around the middle part
of the earth. The very hottest part through the middle is the Equator.
Notice on the drawing that we live in a zone between the very cold
region, or Frigid Zone, and the very warm region, or Torrid Zone. Our
zone is called the North Temperate Zone. We have here spring, summer,
autumn and winter. Our weather is seldom so cold as in the Frigid Zones,
nor so warm as in the Torrid Zone. Our spring and autumn are mild or
temperate.

Find the South Temperate Zone. Its climate is just like ours. What
seasons do they have there? What zone lies north of it and which south
of it?

Copy the diagram of the zones in your note-book.

THE TEMPERATE ZONE--OUR ZONE

Most of the people of the world live in one of the Temperate Zones, and
most of the great cities are in these zones. People can work better here
where we do not have either intensely hot or intensely cold weather all
of the time. There are two Temperate Zones, the North Temperate Zone
and the South Temperate Zone. In which do we live?

Some plants grow best in the Temperate Zones, while others live best in
the Torrid Zone. Scarcely any grow in the Frigid Zones. Name all the
plants you can think of that live in our zone. These plants grow during
the summer and rest or die when winter comes.

SOME PLANTS OF THE TEMPERATE ZONES

Poplar Fruit trees
Maple Wheat
Chestnut Corn
Oak Cotton
Walnut Farm vegetables
Pine Familiar garden plants

None of these plants can grow well in either the intense cold of the
Frigid Zones or the great heat of the Torrid Zone.

Many animals live better in our zone than in any other zone. They need
temperate climate.
