Chapter 5: Land & Water
Assessment: Friday, December 19th
Vocabulary:
landform: different shapes of the Earth
crust: the outer layer of Earth
mantle: a very hot layer under the crust
core: the center of Earth
fresh water: is water that is not salty; found in lakes, ponds, rivers, and streams
ocean: a large, deep body of salty water
earthquake: when Earth’s crust shakes
volcano: an opening in the Earth’s crust; can erupt and a very hot, thick liquid called lava comes out of the opening
flood: happens when rain falls quickly; the ground cannot soak into the ground
landslide: happens when rocks and soil slide from higher to lower ground; rain or snow can cause landslides
Information Need to Know:
What are the parts of Earth? Earth is made up of many landforms such as hills, plains, valleys, and mountains. It is also made up of continents, islands, and oceans. Earth is made up of three layers called the core, mantle, and the crust.
Where can you find fresh water? You can find fresh water in lakes, ponds, rivers, and streams. Plants and animals need water to grow and stay alive.
How do living things use Earth’s water? Some examples of how people use water are to drink, take bathes, cook, and to wash clothes. Animals bathe in water and drink water to stay alive. Plants need water to grow. Animals and plants live in fresh or salt water.
How might Earth’s surface change after a flood? After a flood it would be hard for plants and animals to live there; the soil would be washed away; mud would cover the ground to make it hard to find food.
How does Earth change? Earth can change quickly when the crust moves causing earthquakes, volcanoes, and floods. They can change slowly over time from wind blowing sand and carrying away soil, and ice breaks rocks into little pieces.
Chapter 6: Earth’s Resources
Assessment: Friday, December 19th
Vocabulary
natural resources: a material from Earth that people use in daily life
rock: a nonliving part of earth
minerals: bits of rocks and soil that plants and animals need
soil: a mix of tiny rocks and bits of dead plants and animals
decompose: plant and animals parts rots
pollution: anything that makes water, air, or land dirty
reduce: means to cut back on how much you use something
reuse: means to use something again
recycle: means to make new items out of old items
Information Needed to Know:
How can you classify rocks? You can classify rocks by their shape, size, color, the way they feel, and the type of minerals that make up the rock.
Where can you find rocks? Rocks can be found below and on the Earth’s surface.
How do we use rocks and minerals? People use rocks as tools and to build things. We may use minerals in toothpaste or for jewelry.
How are soils different? There are three kinds of soil; clay soil (orange in color); topsoil (brown/black color); and sandy soil (gray/brown color).
What harms Earth’s resources? Earth’s resources can be harmed by pollution, natural disasters, animals, and people.
What are some of Earth’s natural resources? Some of Earth’s natural resources are air, water, wind, rocks, soil, plants, and animals.
How can we take care of Earth’s resources? People can reduce, reuse, and recycle. We can prevent pollution and litter by getting rid of garbage the right way.
