1.7 - Changes in Volcanic Features

Over long periods of time, volcanic landforms are mainly altered by:

A recently active volcano is often easy to recognise because it has:

A small channel cut into a volcanic slope by runoff is called a:

‘Weathering’ is best defined as the:

‘Differential erosion’ means that:

Which of the following is MOST likely to be seen near a recently active volcanic vent?

As a volcanic cone becomes older, its slopes most commonly become:

In a wet Caribbean climate, which process is MOST responsible for cutting gullies into volcanic slopes after heavy rainfall?

A volcano shows many landslide scars and deep valleys but no fresh lava or ash. This evidence suggests the volcano is:

A student in St Vincent observes thick vegetation on a volcanic slope far from the crater, but sparse vegetation near the top. What is the best explanation?

Which pair of terms correctly completes the chain: breakdown in place → removal and movement?

A field trip in Dominica finds a steep rocky spire where a cone seems to have been removed. The spire is most likely an exposed:

Which observation best supports the idea that a volcano has been recently active?

A crater rim becomes ‘breached’ over time mainly because:

Which sequence best explains how an older volcanic landscape can end up with only core rocks visible?

A drone survey compares two Caribbean volcanoes. Volcano X has sharp crater walls, fresh ash, and sparse vegetation; Volcano Y has rounded slopes, deep valleys, and thick soil. Which conclusion is most reasonable?

Which set of statements is correct? 1. Volcanic features are altered by erosion over time. 2. Recently active volcanoes are easily recognised. 3. Thick soil and dense forest usually indicate very recent eruptions. 4. Gullies can form due to runoff on volcanic slopes.

A planner is choosing a long-term hiking trail on an older volcanic cone. Which sign suggests higher ongoing slope-instability risk during heavy rain?

A student says, “If a volcano has valleys on its slopes, it cannot erupt again.” Which response best evaluates this?

Which option best links a visible clue to the process and the likely age of the volcanic feature?

An island has frequent heavy showers. Which change is MOST likely over decades on an inactive volcanic cone made of loose ash layers?
