Why is it beneficial to be able to predict when and where natural hazards will occur?
So plans can be made to lessen their harmful effects.
To prevent them from happening.
To lessen the power of them.
So people can watch them happen.
Where would you choose to build a house to avoid an earthquake?
A
B
C
D
Where would you NOT want to build a house?
A
B
C
D
Why is it important to predict natural hazards?
It's not
To better prepare for them
So they can be stopped
So people can watch it
How do scientists use historical data to predict natural hazards?
It's not
They use the data to predict natural hazards.
They are able to see places that have had a natural hazard and predict that they are more likely to have them again.
How do scientists use historical data to predict natural hazards?
They don't
They can look at the weather conditions that were present before past hazards, and when the conditions are present again then a hazard is likely to happen.
They can look at the past data to predict when a hazard is likely to happen again.
The movement of sediment from one place to another.
weathering
erosion
deposition
The breaking down of rock into smaller pieces called sediment.

The driveway is long and winding because it bends around a huge old oak tree. The pavement near the tree bulges upward and has many more cracks than the other sections of the driveway.

There is a long meter-deep scar in the soil where a section of the riverbank has slipped into the water and is being washed down the river.

Over time, the Earth's rocks get broken down into smaller pieces. This is called _________________.

When weathered rock is carried away to another location, it is called __________________________

What explanation did Wegener give for fossils of the same plants and animals being found on continents far away from each other?
the ocean used to be dry
the continents had once been joined
land bridges
the plants and animals swam across the oceans
What are two main pieces of evidence for Wegener's theory of continental drift?
some continents look like they fit together like a jigsaw puzzle
fossils of the same species are found on different continents
the oceans have mountains under them
land bridges currently covered by ocean
magma oozes up where the sea-floor spreads apart
The letters on the map represent sectors of the ocean floor. The seafloor is spreading at a rate of 3-5 cm per year at the mid-Atlantic ridge.
In which sectors, is the newest rock located?
AB
BC
CD
AD

What are the three types of Evidence that supports Alfred Wegener's Theory?
Fossils, Fish, and Land
Sedimentary, Magma, and Climate
Fossils, Land forms, and Climate
Climate, Land forms, and Metamorphic rock
What evidence did Wegener use to support his theory?
Continents and fossils fitting together/matching-up like puzzle pieces
glacier scars and other climate evidence from temperature
mountain ranges and rocks line up across continents
all of the above
According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?
Animals easily and frequently travel from Africa to South America.
Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).
Land bridges once existed that connected the continents.
South America and Africa were once connected together.

The type of plate boundary that forms mountains .....
How is the Grand Canyon formed?
Tectonic plates slide past each other creating the canyon.
Tectonic plates moved together creating the canyon.
Weathering and erosion from a river flowing.
It was manmade by digging.
How are caves formed?
Caves are formed by humans breaking a hole in a mountain.
Caves are made by groundwater breaking down rock and moving minerals that forms the cave.
Caves are made by groundwater bringing the rocks together.
Caves are made from erosion breaking down rocks.
