Unit 4 Review MJH

Front

What are the main challenges in sending spacecraft to other parts of the solar system?

Back

The main challenges include the vast distances, the need for advanced technology, the limitations of current propulsion systems, and the harsh conditions of space.

Front

What geological feature is formed when two continental crusts collide at a convergent boundary?

Back

Mountains are formed when two continental crusts push together at a convergent boundary.

Front

What type of plate boundary occurs when tectonic plates move apart?

Back

A divergent boundary occurs when tectonic plates move apart.

Front

Define a convergent boundary in the context of plate tectonics.

Back

A convergent boundary is the place where two tectonic plates come together, often leading to the formation of mountains or subduction zones.

Front

What evidence did Alfred Wegener present to support the theory of continental drift?

Back

Wegener presented evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents.

Front

What is NOT considered evidence supporting the theory of continental drift?

Back

Land features created by erosion are not considered evidence supporting the theory of continental drift.

Front

What is the significance of plate tectonics in understanding Earth's geological processes?

Back

Plate tectonics explains the movement of Earth's lithosphere, leading to earthquakes, volcanic activity, and the formation of mountains.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are convergent, divergent, and transform boundaries.

Front

How do transform boundaries differ from convergent and divergent boundaries?

Back

Transform boundaries occur where plates slide past each other horizontally, while convergent boundaries involve plates pushing together and divergent boundaries involve plates moving apart.

Front

What geological activity is commonly associated with divergent boundaries?

Back

Geological activity commonly associated with divergent boundaries includes the formation of new oceanic crust and volcanic activity.
