How do scientists know the appearance and locations of the continents has changed if they were not able to see the change happening? Select the two choices that best answer the question.

Scientists used evidence from rocks and fossils to provide the age, climate, and topography of the area they were located.

Scientists have hypothesized about the locations of the continents based on magnetic readings from areas around the Earth.

Scientists used evidence from cave drawings to approximate the location, age, and climate of the area the fossils and rocks were located.

Scientists have used evidence of common ancestry, homologous structures, and embryonic development to help link species together on separate continents.

Which of the following answer choices correctly explains how a P-wave moves through medium?

Compresses and release medium as the wave moves

Perpendicular to to the direction of the particle motion.

Particles move up and down will the wave moves left to right

Particles travel in a circular motion while wave moves left to right

Use Diagram 2 from above. This diagram shows the P-waves and S-waves produced from an earthquake. Why do stations I, II, and III show P-waves and S-waves, but station IV does not show an S-Waves?

The S waves could not travel through liquid layers to reach station IV.

The S-waves reached the liquid layer of the Earth and were reflected back to the epicenter.

The S-waves were too fast to be detected by the seismograph.

The S-waves were too slow to be detected by the seismograph.

Which of the following answer choices correctly explains how a S-wave moves through medium?

The material in a S-wave moves perpendicular to the direction the wave travels.

The material compresses and releases as the wave moves left to right.

The material moves in a circular motion while the wave compresses and releases.

The material in a S wave moves side to side and the wave moves left to right.

Which of the following correctly labels the Earth Layers in order A through D?

Crust, Mantle, Outer Core, Inner Core

Outer core, Inner Core, Mantle, Crust

Mesophere, Asthenosphere, Lithosphere, Crust

Crust, Inner core, Mantle, Outer Core

Using the picture above, which of the following explains the direction of the red arrows?

The arrows show convection currents

The arrows show heat energy from the Earth surface

The arrows show heat energy being radiated through the mantle as radioactive isotope decay creating heat energy.

The arrows show dense material rising to the asthenosphere and less dense material sinking back into the mantle.

The picture above shows a trench and a ridge forming on the lithosphere. Which of the following explains the cause of these land formations.

Convection currents cause the tectonic plates to pull away from each other and push together. The movement of the plates create different land forms.

These formations are the result of the sun’s radiation. As the sun radiated energy toward the Earth it cause the lithosphere to move and make different land formations.

These formations cause the plates to continually move and change location.

These formations are billions of years old and formed when the Earth cooled from a mass of molten rock.

Use the Map. Why are most of the volcanoes concentrated together?

Volcanoes tend to form on or near plate boundaries because of plate interaction.

Volcanoes are randomly formed without a cause.

Volcanoes tend to form far away from plate boundaries where there is less plate interaction

Volcanoes are the result of sun exposure and are located near the equator where the temp is higher.

What causes the concentration of Earthquakes shown on Map 5?

Earthquakes occur near plate boundaries and are caused by the interactions of plates.

Earthquakes occur at random and do not have a cause.

Earthquakes occur far from plate boundaries where there is less plate interaction.

Earthquakes are the result of construction and blasting and are more likely to happen near city developments.

How does the material for the island formed?

The material is pushed up from the mantle by convection currents and and has piled up over millions of years to form islands.

The material was pushed up by a convergent boundary millions of years ago and has eroded into islands over time.

The material was dropped by an airplane over head.

The material was formed by the pollution of the world and has formed into islands called the Great Pacific Garbage Patch.

Why is there more than one island?

The plate the island sits on is moving over the hot spot which has created multiple islands.

The garbage patch has continued to grow in size was the world's population has grown.

The water has eroded the material unevenly and the material was originally one large land mass/continent.

The islands were built as a gift to America from other countries and each island was built by a different country.

Which of the following is a benefit of digital signals?

Digital signals can be cleaned easier and more accurately.

Digital signals do not become noisy as they travel.

Digital signals have continuous data.

Digital signals have an infinite value range.

Which of the following is a benefit of analog signals?

Has an infinite range in value.

Signal can easily be cleaned after transmission

Signal can easily be restarted if transmission is interrupted

Travels more accurately over long distances

When engineers are designing an alert system to warn citizens of a potential natural hazard is it important they (pick two answers)

design a system that considers the resources available to protect citizens

communicate/practice how the protection plan will work before it needs to be used.

Design a program in one specific language.

design a system that is generic and basic

The Himalayas are a folded mountain range which continues to grow today. Which of the following explains why we would not see that growth in our life time?

The formation of mountains is caused by tectonic plate movement. Tectonic plates only move a few centimeters each year.

Mountains ranges formed due to tectonic plate movement form at a rate too quickly to observe without out slow-motion video technology.

Mountain ranges caused by tectonic plate movement only increase in height a few centimeters each year.

Mountain ranges are not caused by tectonic plate movement.

Which of the following explains how it is possible to find plant fossils on Antarctica?

The planet was in a different position millions of years ago. The bottom of the planet was rotated upwards allowing for more direct sunlight and warmer temps on Antarctica.

Some plants can survive in below freezing temps.

The continents have shifted locations over millions of years. At one point Antarctica was located closer to the equator.

Antarctica shift locations on a yearly basis. These fossils are probably just a few years old when Antarctica was closer to the equator.
