Week 17

 Hello everyone, this week will be a bit special because we have an outing on Wednesday and we have a day off for Christmas on Thursday.

Anyways, we will have a combined test on Tuesday so please be prepared and study well.

It will be a combined test for Week 16 and Week 17 which means that it'll have elements of both a spelling quiz and a story test in it.

As for the vocabulary portion, we will be directly testing the Week 16 vocabulary, but knowing the 

Week 17 vocabulary will also be helpful for doing well on the test.

Introducing Landforms Summary

Story: https://www.youtube.com/watch?v=iScEVxalbNA

This story is an informational text, and there are no characters in this reading as it is about the geology of various areas of the Earth. (Terra)

It has various settings as it covers several different continents which include a lot of different types of environments and landforms like forests, deserts, oceans, cliffs, coasts, lakes, mountains, valleys, plains, mesas, canyons, and volcanoes. 

The reading starts out by introducing the seven continents in this order: North America, South America, Europe, Asia, Africa, Australia, Oceania, and Antarctica. 

Yes, seven, because Australia and Oceania are often combined together to make a single continent.

Oceans surround the seven continents on various sides.

Next, landforms are introduced as different shapes of land on Earth.

Some landforms are flat and others are steep.

Landforms are shaped by wind, fire, water, and ice.

They can also be shaped or influenced by the movement of the Earth as well as actions of people or animals.

One type of landform is coasts. It is the edge of the land where it meets the ocean.

However, coasts can vary as some coasts have rocky cliffs, and others have beaches.

Rivers and lakes are bodies of water that are on continents.

Rivers are long streams of water, and lakes are bodies of water that have land all around them.

The water found in rivers and lakes is usually fresh water with no salt.

Many lakes form from melting glaciers.

The water in lakes often comes mainly from rivers and streams flowing into them or from rain.

A mountain is a very high area of rocky land.

It has steep sides and is narrow at the top.

Mountains that are small and not steep are called hills.

A group of mountains is called a mountain range.

Valleys, however, are low landforms that are between two or more mountains.

Some valleys have a curved U-shape, and other valleys have a steep V-shape.

Another major landform are the plains.

Plains are huge areas of nearly flat land, and some plains are covered by forests.

Other plains are covered mostly by grasses and flowers with a few trees.

Those plains are called grasslands or prairies, and some people start farms and grow crops there.

Deserts are dry areas that get very little rain, but there are hot deserts and cold deserts.

In the story, we see examples of hot deserts with huge sand dunes and an oasis or two where some trees can grow.

In hot deserts, people can see mesas which are hills and mountains with flat tops and steep sides.

Canyons are landforms that are also found in dry areas and are much deeper than the land around them.

One famous example is the Grand Canyon in Arizona, USA.

Over time, the rivers change the shapes of the canyons.

A volcano is an opening in the Earth's surface which might shoot lava onto the Earth.

However, some volcanoes are dormant and will be unlikely to erupt or explode hot lava.

Lava can build up and make the volcano larger and more like a mountain.

That's the end of the summary!
