Earth's Structures

The geosphere of Earth can be described best by which statement? Select the best answer.

• Earth’s geosphere is made up of solid rocky material and has layers which are very similar

• Earth’s surface is constantly changing, mostly due to the effects of weather and climate.

• Earth’s layers are very distinct, and changes occur at Earth’s surface and below it.

• Earth’s layers are composed of mostly melted  iron and nickel which is very hot

This picture shows a fossil of a whale which was found in Egypt. Scientists have found hundreds of fossils of whales like this in this region. Which claim is supported by this evidence?

• The whales probably washed up on the beach and died.

• The whales probably lived in the ocean. Over time the ocean environment changed and it became land.

• The whales probably had adaptations to live on land.

• The whales probably lived in a lake in Egypt that dried up.

Which statement best supports the idea that the area in which these fossils were found has changed over time? Select the BEST answer.

• The fossils show that sometimes there were animals and other times there were plants.

• The fossils show that at one time the area was an aquatic ecosystem, then it changed to a terrestrial ecosystem.

• The fossils in layer B show organisms that lived at the same time as layer C.

• The fossils show that there were large and small organisms that lived there.

• Take a sugar cube. Run water over it.

• Take sugar and blow it across a table.

• Take a pile of sand and spray water on it.

• Take salt particles and pile them up.

She decided to collect data about the areas and she put her data in this chart.

• Add more soil and make sure the ground is level.

• Put a cover over the area so that rain won’t fall on it.

• Pull up the plants and add rocks.

• Plant grasses or other plants.

How does the theory of plate tectonics support the idea that energy is not created or destroyed but can only be transformed?

• The thermal energy of Earth is transformed to mechanical energy

• The energy at the surface is transformed into electrical energy

• The energy of the moving plates is wasted.

• The radiant energy causes a change in the way the plates move.

A student decided to make a model of a convergent plate boundary. This is what she drew:

An improvement to this model might be to:

• Draw one car slightly on top of the other

• Draw the cars driving very fast

• Draw the cars sliding past each other and scraping the sides.

• Don’t show the cars actually hitting because the plates don’t collide into each other.
