Landforms

Topography = all kinds of lands

Land has many different Shapes

Types of mountains- Rocky (jagged) - Appalachian (lower / round)

Volcanoes = Different mountains

(not in ranges)

Hills like mountains (lower)

Plains = flat Farming

T= Mountain Hills and Plains • Landforms

Topography

Mountains

- Natural land shape feature - Feature

- All kinds of landforms - In certain / specific areas

- landform - Much higher - Occurs in groups / ranges- Mountain ranges differ

T=Mountain, Hills & Plains (2of2)

• Volcanic Areas

• Hills

• Plains

- individual mountains • Steep sides • Rounded slopes

- Large - Flat landforms

• Little relief- relief

• Difference in elevation• Mid US • Great Plains very large plains - Formed in different ways

Essential Question

• What causes changes to landforms?

T= Changes Caused by Wind• Weathering

Sand Dunes

- Wearing away rocks • Natural means

- Weathered pieces • Carried away by wind • Keep moving • Large pieces fall

- Over time • Wind leaves small piles • Piles grow and grow • Piles evolve into dunes

- locations • deserts, beaches & lakeshores• Along the Atlantic Coast

- Heights • As high as 30-story building

- Pros & cons • Protect land during storms • Damage buildings & roads

changes caused by moving water

Main Idea

Moving water Can change the Earth’s surface

Water is POWERFUL! It can dig a mile

deep Canyon

Deposits and water can change the rivers /

Moving water / Erosion

Change the Earth’s Surface

Flowing river erodes Supporting Details /

Reasons / Facts

Moving water - Change path of river - Dig 1 mile deep canyon

River is deeper Sediments moveThen deposited Changing the river

T= Changes Caused by Moving Water • Moving Water

Rapidly Flowing River

- change the Earth’s surface • Carries soil & small pieces of rock

- Erosion • Process of moving sediment

• By wind, water, ice - Water

• Important cause of change • dig a mile-deep canyon • Change path of river

- Erodes • Banks

• Widens river • Bottoms

• Deepens river- Carries sediments

• Deposits • narrow river banks • Bottom shallow

• Emma’s question: What are sediments

• Sediments are rocks, sand and dirt and maybe even natural resources. Jake the Snake

Cause and Effect

How can water cause a river’s bank to change?

(Level 1 / LB)

Main Idea

T= Erosion and Deposition (1 of 2)__ • Moving Water

Rain Water

Ocean Waves

- Creates energy • Moves sediment • The faster it moves = the > energy created • Fast water = erodes a lot • Slow water = erodes small amounts

- Can cause erosion- Moving water carriers sediments - May leave gullies or ditches

- Can change landforms • each wave can bring more sand

- Deposition • Sediments drops out of water

Main Idea

T= Erosion and Deposition (2 of 2)_ • River’s Mouth

Flooding

- place where it empties into the ocean • flow of water slows as it reaches ocean• deposits of sediment settle

• Forms Delta

- An area of new land @ the mouth of a River• Made from sediment

- Can deposit sediment near river • Heavy rain pushes water into banks • Water returns

• Sediment remain • Rich in nutrients • Flood Plains

• Good for farming

Weight can causeroad to collapse

soil, mud and rocks Can make things move

Quickly

Landslides can occur After rain or earthquakes

T= Sinkholes and Landslides • Underground

Gravity

- is powerful, too. • Weather and erode soft rocks

- Underground erosion • Causes caves to form

• Underground caves collapse - Weight on top Underground

• Caves near the surface• Sinkholes may open suddenly

• Large holes • Found where limestone is

• Usually Florida

- Like water, cause land-changing process- Landslides

• Soil, mud, rock move quickly• Happens suddenly

- after earthquakes or heavy rains

T= Plants_( & ) _____________ • Weathering

Roots Protect

Cover Crops

- the process of wearing away- Seed germinates

• Sends roots into cracks / holes • Roots grow

• Can break rocks in pieces

- Preserve Earth’s landforms • holds soil and sand in place

• Helps prevent wind & water erosion

- Helps return nutrients to soil- Trees help prevent wind erosion

The Structure of Earth

Digging deep in the Earth - But it’s not rock

- 4,000 miles is the center of Earth

4 different layers

- 10 major plates- Float & move

- Affect each other

Outer core= liquid Inner core = metal

Crust & mantle are called plates Fit together like a puzzle

Pangea

Plate movements affects Earth’s Surface.

Earthquakes

When plates move, energy is released =

ground shake

Earthquake is movement of

Ground.

focus is placed

3 types of plate movements• Pushed • Sliding • Pulling

Earthquakes occur along a fault

Earthquakes occur a fault

Ritcher Measures how powerful an

earthquake is 2.0 little

6.0 + great damage

What causes an Earthquake

“A sudden release of energy to the Earth’s crust.”

Understanding Earthquakes

• https://www.youtube.com/watch?v=cavq2HFBa-U

• https://www.youtube.com/watch?v=-zNyVPsj8zc

T= Earthquakes___(1 of 2)________ Sudden

Movement

Plate Movement

- 2 plates move • Energy is released in Earth’s crust • Ground shakes

- Focus • place within the crust

• Greatest damage directly above the focus • Cause a lot / little damage

- Epicenter • Directly above the focus

- 3 different types • Plates pushing together • Plates sliding past • Plates pulling apart

T= Earthquakes___(2 of 2)________ Faults

Richter Scale

- Breaks in Earth’s crust - Plate movements bend & crack crust

• Middle of plates • Near edge of plates

- Measures the magnitude • Amount of energy released

• Increase of 1 = 32x • 2.0 too small to feel

- Millions of 2.0 earthquakes/ yearly • 6.0 great deal of damage

- 20 / a year
