Exam Plate tectonics, Weathering Erosion Deposition Volcanoes

Which feature is created by all 3 types of plate boundaries.

• Earthquakes

• Mountains

• Subduction Zones

• Volcanoes

Answer explanation

Earthquakes occur at all three types of plate boundaries: convergent, divergent, and transform. This is due to the movement of tectonic plates, which generates stress and leads to seismic activity.

How do convergent plates move?

• They pull away from each other.

• They slide by each other.

• They move to connect to each other.

• It depends, sometimes they move close to each other, sometimes they move far apart.

Answer explanation

Convergent plates move towards each other, often leading to one plate being forced beneath another in a process called subduction. This is why the correct answer is that they move to connect to each other.

The huge pieces of the earth's crust are called ____________________________. 

• crust

• plates

• directions

• seismos

Answer explanation

The huge pieces of the earth's crust are called plates. These tectonic plates float on the semi-fluid asthenosphere beneath them, and their movement is responsible for geological phenomena such as earthquakes and volcanic activity.

The outside layer of the earth is called ______________________.

• core

• crust

• mantle

• outer core

Answer explanation

The outside layer of the Earth is called the crust. It is the thin, solid outermost layer, while the core and mantle are located beneath it.

Volcanoes that have recently erupted are known as:

• Extinct Volcano

• Dormant Volcano

• Active Volcano

• What's a volcano?

Answer explanation

Volcanoes that have recently erupted are classified as Active Volcanoes. Extinct Volcanoes have not erupted in a long time, while Dormant Volcanoes have the potential to erupt again but are currently inactive.

What is molten rock that has formed deep within the Earth?

• Hot Spot

• Magma

• Lava

• Volcano

Answer explanation

Molten rock that forms deep within the Earth is called magma. It is different from lava, which is magma that has reached the surface. Therefore, the correct answer is magma.

Beneath a volcano, magma collects in a:

• magma chamber

• magma pocket

• vent

• hole

Answer explanation

Magma collects in a magma chamber, which is a large underground reservoir of molten rock. This is the correct term, as 'magma pocket' and 'vent' do not accurately describe the main storage area beneath a volcano.

Erosion ________________________.

• breaks down rock

• moves rocks

• deposits rock

• is caused by ice wedging

Answer explanation

Erosion is the process that moves rocks from one place to another, often through natural forces like water, wind, or ice. While it can break down and deposit materials, the key aspect is that it moves rocks.

Weathering is the__________________.

• breaking down of rocks

• movement of rocks

• deposition of rocks

Answer explanation

Weathering refers to the breaking down of rocks into smaller pieces through processes like wind, water, and temperature changes. This distinguishes it from movement or deposition, which involve the relocation of materials.

Erosion from a mudslide causes a _____________ change.

• chemical

• physical

Answer explanation

Erosion from a mudslide alters the landscape and physical features of the area, making it a physical change. Chemical changes involve alterations at the molecular level, which is not the case here.
