 Waves

• A wave is a disturbance that travels through medium, usually by the transfer of energy.

Forces that Change the Earth’s Crust

The movements of the plates in the earth’s crust.

• Plates – slide past each other.

-push into each other, rock is squeezed.

-pull away from each other, makes a fault.

Types of faults

1.A strike-slip fault-can happen at a transform boundary.

Plates slide, but do not move up or down.

2.A reverse fault can happen at a convergent boundary.

The plates push together, rock above the fault moves up.

3.A normal fault can happen at divergent a boundary.

The plates pull apart, rock above the fault moves down.

An earthquake

• Seismograph is a tool that is used to measure and record earthquake’s activities.

• It helps to find earthquake’s epicenter and to study seismic waves.

Types of seismic waves

1.Surface waves-happens near Earth’s surface.

- move more slowly than body waves.

- cause the most damage.

2.Body waves-move under Earth’s surface.

- move faster than surface waves.

Volcanoes

• Forms at a moving plate boundaries.

• There are 3 kinds of volcanoes.

1.A cinder-cone -is made of small piece of rock called cinders.

has a cone shape with steep sides. 

2.A shield volcano- is made of many layers of rock.

has gently sloping side that looks like a shield

3.A composite volcano -is made of some layers of larva and other layers of ash,Cinders, and rocks

has steep sides that curve inward.

Weathering  

• Weathering is breaking down of rocks into smaller pieces’

• There are two types of weathering.

1.physical weathering- - is caused by –rain, flood, wind, plant’s root, rivers etc

2.Chemical weathering-is caused by –chemical reaction of oxygen and rock minerals.

Soil

Soil is a mixture substance formed by chemical decomposition and physical disintegration of rock.

Types of soil-

1.Clay soil-has fine particles.

- can hold high water, but not much air.

- is not good for the growth of the plant.

2.Sand soil- has very large particles.

- can hold high air, but not much water.

- is not good for the growth of the plant.

3.Loam soil- has medium particles.

- can hold enough air and water.

- is very good for the growth of the plant.

Soil layers:

- top soil- is upper layer of the earth.

- has high humus, water, minerals, and air

• Sub soil- is the middle layer of the soil.

- has some humus, water, and mineral

• Weathered rock- is parental and bottom layer of soil.

- has high humus, water, minerals, and air.

Uses of soil :

- For the growth of the plants. - To get minerals

- For the construction. - As shelter for animals.

Soil erosion- is washing away of soil particles.

-is caused by-rain, flood, wind, deforestation, over grazing, etc.

Ways that are used to protect soil erosion

Planting trees, using terrace and hash, use horizontal plough, avoiding over grazing, etc

Rocks and minerals

Minerals – are tiny parts of rocks.

-have different properties, such as, luster, streaking, shape, hardness, etc.

Rocks - are substances, made from minerals.

Types of rocks

1.Igneous rocks- are formed from melted rock or magma.

-E.g. Granite- is formed inside the ground.

Basalt- is formed on the surface of the ground.

-are used for construction process.

2.Sedimentary rocks- are re formed from sediment. E.g. -limestone, chalk.

-often has fossils.

3.Metamorphic rocks-are formed from other rocks by high pressure and temperature.

- E.g. Marble, slate etc.

 Fossils

• Fossils -are the remains of plants or animals from long ago and found in Earth’s crust.

Steeps of fossils formation

1. An animal or plant dies
2. Sediment buries the animal or plant.
3. Minerals in the sediments change hard parts of the animal or plant to rock.
4. Erosion and movement of rock layers can change the fossil’s location

Uses of : fossils give clue about what Earth was like in the past (earth’s history).

Eras- scientists measure earth’s history in length of time called eras.

1.Precambrian era- is the first era of the earth. Scientists found very few fossil of sea’s organism.

2.Paleozoic era- is the second era of the earth. The first forests started.( ocean life)

3.Mesozoic era- is the third era of the earth. There were many mammals such as dinosaurs, birds, and flowering plants.

4.Cenozoic era- is the fourth era of the earth. There were many mammals.(mastodons)

Air- Air is one of the most important substances for life. One can live without food for some days but it is impossible to live without air even for several minutes. Air was taken as the homogeneous

mixture of different gases. The composition of air by volume ratio is as follows: 78% nitrogen, 21% oxygen, 0.04% carbon dioxide, some water vapor and other gases. The percentage of water changes from place to place.

Importance of Air

Air is necessary for all living organisms.

1.For photosynthesis Air supports burning. e.g. oxygen

2.For science and technology development. it extinguish fire. e.g. carbon dioxide for breathing

Properties of air are;

1.Volume: Air occupies space i.e., it has volume but not definite volume.

2.Air moves from place to place

3.Air is odorless and colorless.

4.Air supports burning.

5.Air moves from place to place

Density: Air has its own density. Density is the ratio of mass to volume. i.e. Density = Mass Volume The density of air is 1.27 g/L
