Science 7 Sem. 2 Review

Front

At the science fair, Aria, Arjun, and Maya are checking out a cool diagram of Earth's layers: the crust, mantle, and core. They want to add a fun caption that explains how energy travels inside our planet. Which statement would make their display both accurate and awesome?

Back

Energy moves from the warmer core up to the cooler crust.

Front

How do the effects on Earth's surface from a volcanic eruption and a river carving compare? hint time vs. space scale

Back

The volcanic eruption is a rapid, large-scale change, while the river carving is a slow, large-scale change.

Front

Why are there more earthquakes and volcanoes along the western edge of South America than the eastern edge?

Back

The western edge is part of the Ring of Fire, where tectonic plates meet and interact, causing more earthquakes and volcanoes.

Front

Why do earthquakes seem to shake things up in California way more than in Texas?

Back

California is located near the boundary of two tectonic plates, making earthquakes more frequent there than in Pennsylvania.

Front

William and Nora are watching a video about earthquakes. They see two tectonic plates sliding past each other horizontally. Which type of plate boundary are they learning about?

Back

Transform

Front

James, Anika, and Olivia are exploring a map of Earth's tectonic plates for their science adventure! They want to figure out the type of plate boundary at a certain spot. What is the best way for them to identify the type of plate boundary at that location?

Back

By analyzing how the plates move relative to each other at the boundary

Front

Jackson, David, and Arjun are looking at the map above and imagining what the world looked like millions of years ago! Which observation would help them best support Wegener’s idea of continental drift? The coastlines of continents appear to match up closely. There are similar animal fossils on different continents. Some continents have matching climate patterns. Continents have similar types of soil.

Back

The coastlines of continents appear to match up closely.

Front

Maya, Benjamin, and Michael are on a submarine adventure, exploring the ocean floor! As they travel away from the Mid-ocean Ridge, they start to wonder about the age of the oceanic crust beneath them. What can they infer about the age of the oceanic crust as they move farther from the Mid-ocean Ridge?

Back

The oceanic crust becomes older as you move farther from the Mid-ocean Ridge.

Arrange the sequence of events during a volcanic eruption: Magma rises beneath the surface → Pressure builds in the magma chamber → Volcano erupts → Lava flows out

Back

Magma rises beneath the surface → Pressure builds in the magma chamber → Volcano erupts → Lava flows out

Front

Based on the trends shown in the graph, what type of ecological interaction do you think is happening between the moose and wolf populations?

Back
