Questions and Answers
- 1.
A large moving block of ice is called a _________.
- A.
Deposition
- B.
Glacier
- C.
Mountain
- D.
Volcano
Correct Answer
B. GlacierExplanation
A large moving block of ice is called a glacier. Glaciers are formed over long periods of time when snow accumulates and compacts into ice. Due to their immense weight, glaciers slowly flow downhill, carving out valleys and shaping the landscape. They are found in polar regions, high mountains, and some parts of the world where the climate is cold enough for ice to persist year-round. Glaciers play a crucial role in regulating Earth's climate and are important sources of freshwater.Rate this question:

A volcano is a mountain that is formed when _____________.
- A.
Two plates collide and niether gives.
- B.
When lava flows through a crack onto Earth's surface.
- C.
When the sun melts rocks.
- D.
When water runs through a valley.
Correct Answer
B. When lava flows through a crack onto Earth's surface.Explanation
A volcano is formed when lava, which is molten rock, flows through a crack or opening in the Earth's surface. As the lava reaches the surface, it cools and solidifies, building up layers of volcanic rock over time. This process creates a mountain-like structure known as a volcano. The option "when lava flows through a crack onto Earth's surface" accurately describes this process of volcano formation.Rate this question:

3, the crust, the center, and the mddle.
- C.
4, the crust, the mantle, the outer core, and the inner core.
- D.
0, it is a solid piece of rock the whole way through.
Correct Answer
C. 4, the crust, the mantle, the outer core, and the inner core.Explanation
The correct answer is 4 because the earth is composed of different layers. The crust is the outermost layer, followed by the mantle, the outer core, and the inner core. These layers have different compositions and properties, with the inner core being the hottest and the outer core being liquid.Rate this question:

Deposition is ____________________.
- A.
The dropping of bits of rock and soil as water flows.
- B.
A crack in a glacier.
- C.
An old river.
- D.
A canyon wall.
Correct Answer
A. The dropping of bits of rock and soil as water flows.Explanation
Deposition refers to the process of dropping or depositing bits of rock and soil as water flows. This occurs when the velocity of the water decreases, causing it to lose its ability to carry sediment particles. As a result, the sediment settles and accumulates on the riverbed or any other surface it comes into contact with. This process is essential in shaping the Earth's surface and can lead to the formation of various landforms such as deltas, alluvial fans, and floodplains.Rate this question:

A glacier forms when _______________.
- A.
Snow piles up and packs down until a large mass of ice forms. When this ice moves it becomes a glacier.
- B.
When a mountain splits into two pieces.
- C.
When water freezes on a lake.
- D.
None of the above.
Correct Answer
A. Snow piles up and packs down until a large mass of ice forms. When this ice moves it becomes a glacier.Explanation
A glacier forms when snow piles up and packs down over time, gradually forming a large mass of ice. As more snow accumulates, the weight and pressure cause the snow to compress and transform into ice. When this ice starts to move under its own weight, it becomes a glacier. This process of accumulation and movement is what distinguishes a glacier from simply frozen water on a lake or a mountain splitting into two pieces. Therefore, the correct answer is that a glacier forms when snow piles up and packs down until a large mass of ice forms, which then moves and becomes a glacier.Rate this question:

What conditions are needed for wind erosion?
- A.
Conditions must be dry and windy where soil is loose and can be easily moved.
- B.
Conditions must be wet and salty.
- C.
None of the above.
Correct Answer
A. Conditions must be dry and windy where soil is loose and can be easily moved.Explanation
Wind erosion occurs when there are dry and windy conditions, coupled with loose soil that can be easily moved. In such conditions, the force of the wind can pick up and carry away the loose soil particles, causing erosion. Wet and salty conditions do not facilitate wind erosion, as the moisture and salinity of the soil make it more cohesive and less prone to being moved by the wind. Therefore, the correct answer is that wind erosion requires dry and windy conditions with loose soil.Rate this question:

What is magma?
- A.
Hot gases
- B.
Hard rock
- C.
Melted rock
- D.
Hot metals
Correct Answer
C. Melted rockExplanation
Magma is melted rock that exists beneath the Earth's surface. It is formed when solid rocks in the Earth's mantle and crust melt due to high temperatures and pressure. Magma is typically composed of a mixture of molten minerals, gases, and dissolved water. It is the precursor to volcanic eruptions and can eventually solidify and form igneous rocks when it cools and crystallizes.Rate this question:

- B.
A man-made lake or park.
- C.
All of the above.
- D.
None of the above.
Correct Answer
A. A natural feature on Earth's surface.Explanation
The correct answer is "a natural feature on Earth's surface." This answer is supported by the definition of a landform, which refers to any natural feature or shape that appears on the Earth's surface. This can include mountains, valleys, plains, plateaus, and other geological formations that are not man-made. The other options, "a man-made lake or park," "all of the above," and "none of the above," do not accurately describe the concept of a landform.Rate this question:

A mountain is land that is higher than the land around it.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because a mountain is indeed land that is higher than the land around it. Mountains are formed through various geological processes such as tectonic plate movements or volcanic activity, resulting in their elevated height compared to the surrounding areas. They are characterized by steep slopes, rugged terrain, and often have peaks or summits. Mountains are important features of the Earth's landscape and can have significant impacts on climate, ecosystems, and human activities.Rate this question:

Deltas form at the end of rivers. Dunes form in dry areas when wind carries sand.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Deltas are landforms that form at the mouth of a river where it meets a body of water, such as a lake or an ocean. They are created by the deposition of sediment carried by the river, which accumulates and shapes the land over time. Dunes, on the other hand, are formed in dry areas when wind carries and deposits sand. The given statement correctly states that deltas form at the end of rivers, while dunes form in dry areas with wind-blown sand, making the answer "True" accurate.Rate this question:
