Black Blizzards and the Dust Bowl

1 Monday, January 27 Black Blizzards and the Dust Bowl By Colleen Messina If you walked out the door of your house and saw a towering black pillar of clouds one thousand feet tall, what would you think? This might sound like a scene from a sci-fi film. However, people saw this often during the 1930s when these "black blizzards" swept across the area of the Midwest called the Dust Bowl. What caused these strange black storms? Farmers in the Midwest dug up the buffalo grasses that had held down the prairie soil for thousands of years. These grasses had extensive root systems that held the soil together. The farmers removed the native grasses so they could plant crops. Livestock grazed on grass on the rest of the land, too. Farming and grazing destroyed the natural system that had preserved soil on the prairies. Farming and grazing hurt the prairie, but then a terrible drought hit the area too. The misuse of the land and the severe drought combined to create the Dust Bowl - a vast, parched area in the Midwest. The Dust Bowl affected one hundred million acres of land. The resulting black blizzards happened when millions of tons of dirt were swept from the parched, barren fields and swirled up into the air. Scientists called the Dust Bowl of the 1930s the "decade-long disaster" because these conditions lasted for about ten years. Over 2.5 million people left the Dust Bowl and migrated west. Those who moved did not have an easy life. They thought that California would give them a better life, but they were often disappointed. Migrants were told that there was nothing there for them, or police turned them away at the border. Life in the "promised land" was not what the migrants expected. John Steinbeck described a scene from the Dust Bowl in his book The Grapes of Wrath. He wrote about families who moved west from Kansas, Oklahoma, Texas, Nevada, and Arkansas. He wrote,"car-loads, caravans, homeless and hungry; twenty thousand and fifty thousand and a hundred thousand and two hundred thousand. They streamed over the mountains, hungry and restless -restless as ants, scurrying to find work to do - to lift, to push, to pull, to pick, to cut - anything, any burden to bear, for food." His words captured the tragedy of the Dust Bowl. For those who stayed in those states, life in the Dust Bowl was a nightmare. Winds blew at over fifty miles per hour. People who didn't move away suffered from lung damage, disease, or even death because of the dust in the air. Plagues of insects and animals also made life even harder. Livestock had problems. Cattle ended up with "mud balls" in their stomachs. They got mud balls from dust-coated grass. Many cows died. Dust coated and clogged up barns, homes, and farm equipment. Dust and sand damaged car engines. The black blizzards were hard on everyone and everything. Every family kept a shovel close by to dig out buildings and equipment! Lorene White has a clear memory of the first time she saw a black blizzard. She was fourteen years old in She lived on her family's farm in western Kansas. She was playing outside and noticed a big, dark cloud bank. It did not look like a normal rain cloud. She saw birds frantically flying ahead of the storm to get away from the storm. She remembers how scared her family felt. They had never seen anything like it. The Dust Bowl and its black blizzards created more economic problems for the country when many people were already struggling. The Great Depression started before the black blizzards, but the storms caused more money problems. Farmers no longer made a profit on their crops. They lost their land. The banks and the government took over their properties. Many lessons were learned from the Dust Bowl, then and now. Today, meteorologists use computer models to

2 Monday, January 27 study the climate of the Dust Bowl. They have learned more about what conditions combined to cause that disaster. By taking good care of the environment, and especially by using better farming methods, Americans will never see the terrible black blizzards again. Black Blizzards and the Dust Bowl Questions 1.

4 Tuesday, January 28 What Are Earthquakes? By Cindy Grigg Caption: This picture shows part of the damage from a major earthquake that struck San Francisco, California, April 18, The outside of the Earth is called the crust. Just like the crust on a loaf of bread, the Earth's crust has cracks in it. The cracks are called faults. The crust of the Earth isn't solid at all. It is made up of many pieces called plates. The plates of the Earth's crust fit together like a giant puzzle. But unlike a puzzle, the plates of the Earth's crust are always moving. The Earth's plates float on a layer of hot, melted rock. This part of Earth is called the mantle. Most earthquakes happen where two plates meet. The Earth's plates don't always slide smoothly past each other. Their rocky edges are jagged and rough. Sometimes they get stuck. The force causing them to move builds up. Something has to give. The plates may break apart with a huge jerk. Shock waves spread out from the focus of the earthquake. The focus is the place where an earthquake begins. Some of the shock waves travel to the surface of the Earth where people are. What is an earthquake like? The ground starts to rumble and shake in an earthquake. It may crack open. Sometimes the ground moves. It moves like ripples move across water. The shaking may only last for a few seconds. But earthquakes can cause awful damage. In large earthquakes, buildings, roads, and bridges may give way. Gas lines may break, causing fires. In mountain areas, an earthquake can cause a landslide or mudslide. This happens when giant amounts of rocks, dirt, and mud slide down the mountain. An avalanche is when giant amounts of snow slide suddenly down the mountain. When these things happen, they can destroy buildings. They can cover large areas with mud, dirt, or snow. Everything in their path is flattened. If an earthquake happens under the ocean, it causes giant waves called tsunamis. When a tsunami comes to land, the giant wave of water can cause great damage. Every year there are more than half a million earthquakes in the world. Most of them are small. People don't even notice them. Many others cause just a little damage. A few earthquakes are big enough to cause much damage and many deaths. Our Earth is dynamic. This means it is active, and it is always changing. Earthquakes are one of the most powerful changes that happen on Earth. What Are Earthquakes? Questions 1. The place where an earthquake begins is called the.

6 Wednesday, January 29 Big, Black Blizzards! By Colleen Messina What would you do if you saw a big black cloud? What if it was one thousand feet tall! You might say, "Wow!" You might be surprised! These storms happened a lot in the 1930s. They were called black blizzards. They were in the Midwest. They were in a spot called the Dust Bowl. Why did these storms happen? Farmers in the Midwest dug up the soil. They got rid of native grass. That grass had been there for a long time. The grass helped the prairie. It kept the soil moist. Farmers took it away so they could plant crops. Cows also grazed on the grasses. Farming and grazing made the prairies drier. Then, a drought happened. A drought is when very little rain falls. The soil became even drier. The wind blew hard. Then, soil and dust was swept into the air! The soil and dust made the storm look black. These storms affected a lot of land. The area became even drier and dustier. It was called the Dust Bowl. These conditions lasted for about ten years. Black blizzards made life terrible. People got sick. Animals got sick. Cows ate grass with dust on it. It gave them mud balls in their stomachs. The weather was hot. The temperature went over one hundred degrees in the summers. The dust hurt machines. Car engines got clogged. Barns and houses were damaged. Families kept shovels close by to use after a black blizzard. Sometimes they had to dig out their houses! Some people moved away from the Dust Bowl. They went west. Many went to California. However, life was still hard there. Some people told them to go away! This was hard on families. They had a lot of money problems. This time period was called the Great Depression. It was a hard time for the country. Many people were poor. People learned a lot from the Dust Bowl and from the black blizzards. Today, farmers take better care of the land. They hope that the black blizzards will never happen again! Big, Black Blizzards! Questions 1. When did the black blizzards happen? A. in the 1920s B. in the 1890s C. in 2008 D. in the 1930s 2. What kind of farm animal did the article say grazed on the prairies? A. goats B. sheep C. cows D. horses

8 Thursday, January 30 Tsunami: What a Wave! By Brandi Waters Do you ever think about what goes on at the bottom of the ocean? It is probably a lot more than you think! Volcanoes can start at the bottom of the ocean. Earthquakes can happen there, too. No big deal, right? No people. No buildings. No danger. No one can get hurt out in the middle of the ocean, right? Wrong. A powerful earthquake or volcanic eruption can kill many people, even when it happens in the middle of the ocean! When they happen at the bottom of the ocean, they make the water move. Rippling waves rush out from the spot where the earthquake or eruption took place. The waves move out in every direction. They can move as fast as four hundred fifty miles per hour! These waves are called tsunamis. When tsunamis get close to land, they get much taller. This is because the ocean is not as deep near the shore. Some waves can be up to one hundred feet tall! These giant waves can do a lot of damage when they crash onto the shore. They can destroy buildings. They can cause flooding. They can cause people to drown. Tsunamis are very dangerous. Tsunami: What a Wave! Questions 1. A tsunami is. A. an earthquake B. a series of strong waves C. a volcano D. all of the above 2. Tsunamis begin. A. at the bottom of the ocean B. when a powerful earthquake happens underwater C. when a volcano erupts underwater D. all of the above 3. When tsunamis get close to the shore, they. A. move faster B. get taller C. move slower D. get wider 4. Tsunamis can move as fast as.

9 Thursday, January What kind of damage can a tsunami cause? Which do you think is more dangerous: an earthquake on land or tsunami caused by an earthquake? Give reasons to support your answer.
