Sci HSA Part 1

What color in the visible spectrum has the most energy?

• Yellow

• Red

• Orange

• Blue

• Green

The average salinity of ocean water is about 35 parts per thousand. How does an increase in evaporation of ocean water affect salinity at the ocean surface?

• Ocean salinity decreases

• Ocean salinity increases

• Ocean salinity remains the same

• Ocean salinity varies in a cyclical

  pattern

For fifty years beginning in 1940, volunteers counted the number of birds in different habitats around Honolulu for one day each year. The graph shows the data for the annual bird count during this time

Which statement best describes

the trend in the data from

1940 to 1990?

• The number of birds seen

  increased exponentially,

  doubling about each decade.

• The number of birds seen

  increased exponentially,

  doubling about every 20 years.

• The number of birds seen increased

  steadily at a rate of about 30 birds per decade

• The number of birds seen increased steadily at a rate of

  about 50 birds per decade.

Which of the following best describes Earth's tectonic plates?

• They move away from each other at the equator

• They move because of convection currents in the mantle

• They collide at midocean ridges

• They form at subduction zones

Students create the classroom model shown in the diagram . A cup of dyed ice water is attached to the inside of a tank filled with water at 30^oC. The ice water flows into the tank through a small hole in the bottom of the cup, as shown

Select the two large systems the student can investigate using this model

• Density Current

• Global wind current patterns

• Ocean water biomes

• Temperature profile of ocean water

• Upwelling of water currents

Students make a model of the solar system. They want the objects in their model to correctly represent the size relationships of objects in the solar system. The ratio of the diameter of the sun to the diameter of Earth is approximately 100:1.

Which items would best represent the sun and Earth in the students’ model?

• 
• 
• 
• 

Humans accidentally introduced a new predator into an ecosystem. It began to act as an invasive species by preying on a native animal.

Which graph shows what would have happened to the invasive species in this new ecosystem?

•

Which diagram correctly orders different colors of light according to the value of a property?

A rock is pushed deep underground in an area where mountain - building is occurring, and undergoes the following processes.

First, the rock experiences high pressure that causes its minerals to align themselves in bands.

Second, the rock is pushed further underground and completely melts, then erupts from a volcano and hardens.

Third, the rock is broken down by wind and water into small particles, which flow into a river and get compressed into rock.

Which order correctly shows this progression of rock types?

• igneous ---> metamorphic ---> sedimentary

• metamorphic ---> igneous ---> sedimentary

• metamorphic ---> sedimentary ---> igneous

• sedimentary ---> igneous ---> metamorphic

• Law of Fortnite

The diagram below shows the tilt of Earth’s axis while Earth is in a certain position in its orbital path around the sun.

In this diagram, what season is it in the northern hemisphere?

• Spring

• Summer

• Winter

• Fall

• Light Work
