Gravity and Mass Movement

Types of Mass Movement

100

Is the most common form of Mass Movement, and is very slow.

Creep

200

The downslope movement of rock, earth, or debris, and often starts from gravity, heavy rain, earthquakes, and human things and activities.

Landslides or Falls

300

Occur when intense rainfall, post-wildfire, sloping terrain, volcanic activity, and human things and activities, and are a very fast form of Mass Movement

Mud Flows

400

Is the process of rapid free-falling or bouncing, or detached rocks fall from steep slopes or cliffs, often occur from gravity, water, weathering, and earthquakes

Rockfall

500

Is a specific material, mad from a mix of snow from the tip of a volcano, mixed with the ash and lava from inside a volcano, which then makes a very dangerous type of mud flow that causes more casualties then lava in areas around volcanoes

Gravity and Mass movement facts

100

True or False, Gravity can be seen by the naked human eye

False

200

Does gravity become stronger with movement or weaker with movement

Weaker With Movement

300

What is the main cause of Mass Movement

Gravity

400

How can Gravity and Mass Movement be dangerous?

They change landscapes, which pose a big risk to human houses and structures

500

Name four different forms of Mass Movement

Landslides, Creeps, Mud flows, Rockfalls, Falls, Lahars, and Slumps

Affects on Erosion

100

What is one way gravity affects erosion

It pulls objects like rock, soil, and debris down hills

200

Does Gravity and Mass Movement directly reshape land forms or non directly change landforms

Directly

300

What are two of the most common types of Mass Movement and Gravity that effects Erosion

Creeps, Landslides, and Mud Flows 

400

What materials are often mixed together by Mass Movement and Gravity that cause those objects to erode and go downhill

Heavy rainfall and Soil

500

How do human activities effect things like Mass Movement and Gravity, and cause Erosion to form

By doing things like disturbing soil b removing Vegetation

How it changes ocean tides

100

During a Spring Tide, when the moon's force is stronger, would it make larger or smaller high tides

Larger

200

How does the moon cause high tides

The moon's gravitational pull is stronger than the ocean on the opposite side of the world, and causes high tides

300

True or False, when the sun and moon align they create higher high tides and lower low tides

True

400

What strong forces from the moon create this type of Tide

King Tide

500

Every how many hours do coastlines into and out of water bulges

24 hours

Speed of different Mass Movement forms

100

Very Slow, moves only millimeters to centimeters per year

Creeps

200

Very fast mixture of water and rock

Mudflow

300

Fast free-falling of rock, soil, and debris going down a hill

Rockfalls

400

Very Rapid in pace

Rockslides or Landslides

500

Is moderate to fast 

Slumps
