What type of plate boundary is shown in this illustration?

When mantle rocks near the radioactive core are heated, they become less dense than the cooler, upper mantle rocks. These warmer rocks rise, while the cooler rocks sink. This movement of warmer and cooler mantle rocks creates pockets of circulation within the mantle called _________, which are thought to be the force behind the movement of tectonic plates over the asthenosphere.

Earth's layers formed as result of differentiation. During differentiation, elements and compounds formed varied layers of minerals. Minerals with low densities tend to crystalize from magma at cooler temperatures; minerals with greater densities crystalize at higher temperatures. Think about the zones or layers of the Earth. We would expect the rocks in the mantle to have a high proportion of

Which has MOST contributed to our understanding of the existence of the Earth’s mantle and core?

____________________ helps explain why there are a large number of marsupial mammal species in Australia and South America, two continents that were once connected.

Which geological features MOST LIKELY prompted the development of the theory of plate tectonics?

The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?

According to the map, the area of the continental United States MOST LIKELY to have volcanic activity is the

Which of these pieces of evidence did NOT help in the development of the theory of plate tectonics?

If left in the sun, which would increase in temperature FIRST?

Use the weather map seen here to describe the predicted weather conditions.

Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. On weather maps, you may have noticed areas that have a large L or H over a region with lines circling around them. The L stands for low pressure and H stands for high pressure. The lines circling them are isobars.

Check out the pressure system and isobars over Georgia and Florida. What is the present weather in this area ?

Mary used a thermometer to measure the temperature of water at different states. What would the Celsius thermometer read when water froze and became a solid?

Usually air moves from

The image shows the three-day cone forecast of a hurricane. Four locations (I, II, III, IV) are labelled on the diagram.

The hurricane center is MOST likely to be near location ___________ on Monday afternoon.

The image shows the cone forecast map of a hurricane.

Four locations (I, II, III, IV) are labeled on the diagram. At which of the four locations is the hurricane predicted to be LEAST intense?

Which statement BEST describes the risk of damage due to the hurricane at P?

A hurricane is MOST LIKLEY to occur in an area

Scientists use technology to help predict severe weather such as hurricanes and tornadoes. Using technology, they can create maps like this one. What is the MOST important reason that scientists track hurricanes? In the image given.
