Earthquakes or volcanic eruptions cause tsunamis. The wavelengths of tsunamis are longer than those of regular waves. A wave in a tsunami can be up to 120 miles long. Tsunamis can travel long distances before reaching the shore. Before a tsunami hits, the water near land draws backward. This event is called a drawback. Entire bays can nearly empty of water before a tsunami strikes.

The largest recorded tsunami wave struck Alaska in 1958. The height was 1720 feet tall. The waves destroyed land and vegetation. What was likely future impact on the land after the tsunami?

• Alaska had less land for the farming and forestry industry.

• There was likely more future flooding due to a lack of vegetation.

• There was less wildlife to eat vegetation.

• The wave caused increased physical weathering on rocks, changing the landscape.

In China, you can find the world's deepest sinkhole. The Heavenly Pit, as it's called, is 1,677 to 2,172 ft deep. Sinkholes form when the rock below the ground collapses. The ground underneath the soil weathers and transforms because of changes in the rock layers.

Megan visits the Heavenly Pit sinkhole. She is told the rock around the sinkhole is limestone. The limestone did not allow the excess soil to remain on top of it, causing the sinkhole to form. What type of weathering is this an example of?

• physical weathering

• manmade weathering

• erosion

• chemical weathering

After a minor tsunami, a local beach lost half a mile of sandy coastline. Which is the most likely explanation for what happened to the sand?

• The sand dissolved in the water.

• The sand was pulled into the ocean through a drawback.

• The sand became salt.

• The sand was deposited in other water systems.

"Nutria" (Coypu)

Nutria became part of Louisiana's ecosystem during the 1930's. They were brought in to the state for their furs. Nutria escaped the fur farms and created habitats in marshland. Their sharp teeth chewed through all types of vegetation. They also chewed through irrigation systems and the wood on houses.

A local nutria population has become a problem for a marshland. The park service wants to solve the erosion problem caused by the nutria. Which would not be a good solution to decrease the population.

• trapping

• shooting

• poisoning the entire water of marshland

The venus flytrap is an amazing plant. It developed unique external structures to capture prey. The plant mostly gets its nutrients from the gases in the air. However, the plant lures and traps insects. The "mouths" of the flytrap have soft hairs called cilia outside and inside. When a fly tickles the cilia, the leaves snap shut. Inside the leaf, digestive juices break down the soft parts of the fly. The hard parts of the fly are ejected from the leaf days later.

Marley tries to feed her venus flytrap a dead fly. The leaves do not close over the fly. What can Marley do to make the flytrap's leaves close?

• Spray water on the flytrap leaves.

• Add another fly to the leaves.

• Tickle the cilia to make the leaves close.

• Put the plant out in the sun.

Venus flytraps usually grow in damp, humid climates. A new species is created in which they can withstand hotter, drier conditions. What type of internal-external structures would NOT the plant develop?

• brighter colors

• deeper roots

• larger cilia

• water storage system

Homing pigeons are able to find their way home across long distances because the iron in their beaks acts like a compass. The longest flight completed by a homing pigeon was 1,1000 miles. Homing pigeons were used to carry messages. A small tube was attached to the birds' leg where the message was placed. The pigeon would deliver its message to its destination than fly back "home".

Kieran sends a homing pigeon from his house in New Orleans to Baton Rouge. The pigeon gets lost on its way back. What may have happened to cause the pigeon to get lost?

• the bird lost his map

• the bird lost his compass

• the bird had beak damage, removal of home site, or a disruption of magnetic waves

• the bird hit his head and suffered memory loss

"Thorny Devil"

In the hot desert, there is not much water for the thorny devil lizard. The lizard had to adapt to its environment. Its skin absorbs water. The scales on its body collect the water from the air and channel it to the lizard's mouth. The lizard drinks the water, allowing it to survive.

Anya is a wildlife specialist. She finds a thorny devil near a swamp. Select how the thorny devil would NOT most likely adapt to the wet conditions.

• webbed feet

• skin like a snake or frog

• feathers or fur

"Source 4: Pollination"

Neal owns a sunflower farm. Insects keep eating his sprouts, so he sprays a pesticide. Later, Neal realizes the chemicals killed the bees and his flowers are not pollinated. Neal wants to ensure his flowers grow again.

PART A:

What would be a logical first step for Neal to recover his sunflowers?

• Wash away the pesticides on his sunflowers.

• Plant an adjacent field of flowers which attract pollinators.

• Cut down his current crop and replant.

• Build hives around the sunflower field.
