3.
A looping curve in a river may be cut off to form an oxbow lake.
Explanation
A looping curve in a river may be cut off to form an oxbow lake. This is because rivers are constantly changing and eroding their banks. Over time, the force of the water may cause the outer bend of a river's meander to erode, creating a shortcut between the two ends of the loop. Eventually, the river may abandon the loop altogether, leaving behind a curved lake called an oxbow lake. This process is a natural occurrence in river systems and can be observed in many locations around the world.

Materials that water cannot pass through easily are called impermeable.
Explanation
The statement correctly defines impermeable materials as those through which water cannot pass easily. Therefore, the correct answer is True.
7.
Plants grow throughout a pond because the water is shallow enough for _______________ to reach the bottom.
Correct Answer
sunlight
Explanation
Plants require sunlight for photosynthesis, a process in which they convert sunlight into energy. In a pond, if the water is shallow enough, sunlight can penetrate through the water and reach the bottom. This allows plants to receive the necessary sunlight for their growth and survival. Therefore, the presence of sunlight reaching the bottom of the pond is the reason why plants can grow throughout the pond.
8.
Materials that do not allow water to easily pass through, or permeate, are called permeable.
Explanation
Permeable materials allow water to easily pass through, while impermeable materials do not. Therefore, the correct answer is false, as materials that do not allow water to easily pass through are called impermeable, not permeable.
9.
A river and all its tributaries together make up a
Correct Answer
river system
Explanation
A river system refers to the main river and all its tributaries that flow into it. The tributaries contribute to the overall flow and volume of water in the main river. Together, they form a network of interconnected waterways that drain into a larger body of water such as a lake or an ocean. A river system is essential for the circulation of water, nutrients, and sediment, as well as for supporting various ecosystems and human activities along its course.
10.
___________________ are huge masses of ice and snow that move slowly over the land,
Correct Answer
Glaciers
Explanation
Glaciers are massive bodies of ice and snow that slowly move over the land. They are formed over long periods of time from compacted snow and ice, and their movement is driven by the force of gravity. Glaciers can carve out valleys, create lakes, and reshape the landscape as they flow. They are found in areas with cold climates and abundant snowfall, such as polar regions and high mountain ranges. Glaciers play a crucial role in shaping the Earth's surface and are important indicators of climate change.

14.
A ___________ is a type of hot spring from which the water bursts periodically into the air.
Correct Answer
geyser
Explanation
A geyser is a type of hot spring that periodically shoots water and steam into the air. This occurs due to underground volcanic activity, where the water is heated and pressurized by magma. Eventually, the pressure becomes too great and the water bursts out, creating a spectacular display. Geysers are typically found in areas with geothermal activity, such as Yellowstone National Park in the United States.
15.
People can obtain groundwater from an ___________________ by drilling a well below the water table.
Correct Answer
aquifer
Explanation
An aquifer is a natural underground layer of permeable rock or sediment that holds and transmits water. By drilling a well below the water table, people can access the water stored in the aquifer. This is because the water table represents the upper boundary of the saturated zone within the aquifer, where the spaces between the rock or sediment particles are filled with water. Therefore, drilling a well below the water table allows people to tap into the groundwater stored in the aquifer and obtain a reliable source of water.
16.
A well in which water rises because of pressure within the aquifer is called an _________________________.
Correct Answer
artesian well
Explanation
An artesian well is a well that has water rising to the surface due to the pressure within the aquifer. The pressure in the aquifer is typically caused by the presence of a confined aquifer, which is sandwiched between impermeable layers of rock or clay. When a well is drilled into this confined aquifer, the pressure forces the water to rise naturally without the need for pumping. This phenomenon is what distinguishes an artesian well from other types of wells.
17.
One watershed is separated from another by a ridge of land called a _____________________.
Correct Answer
divide
Explanation
A watershed is a geographical area where all the water drains into a common point, such as a river or a lake. The question asks for the term used to describe the ridge of land that separates one watershed from another. The correct answer is "divide." This term refers to the physical barrier that separates the flow of water between different watersheds.
18.
___________________ are the smaller streams and river that feed into a main river.
Correct Answer
Tributaries
Explanation
Tributaries are smaller streams and rivers that flow into a larger, main river. They contribute to the overall flow and volume of water in the main river. Tributaries can come from various sources such as rainfall, melting snow, or underground springs. They play a crucial role in the water cycle and the overall health of river ecosystems by providing freshwater, sediment, and nutrients to the main river.
19.
Watershed
Correct Answer
A. The land area that supplies water to a river system
Explanation
The correct answer is: the land area that supplies water to a river system
20.

21.
The particles of rock and soil that are picked up and moved by erosion and deposition are called ___________________.
Correct Answer
sediments
Explanation
Erosion and deposition involve the process of picking up and moving particles of rock and soil. These particles, when transported by wind, water, or ice, are referred to as sediments. Sediments can vary in size, ranging from tiny grains of sand to larger pieces of gravel or even boulders. They are often found in bodies of water, such as rivers, lakes, and oceans, where they can settle and accumulate over time. Sediments play a crucial role in shaping the Earth's surface and can provide valuable information about past geological events.
22.
A flood occurs when the ____________ of water in a river increases so much that the river overflows its channel.
Correct Answer
volume
Explanation
A flood occurs when the volume of water in a river increases so much that the river overflows its channel. The volume refers to the amount or quantity of water present in the river. When this volume exceeds the capacity of the river channel, it leads to flooding as the excess water spills over onto the surrounding land. Therefore, a high volume of water is the main factor that causes a flood.
23.
Tributary
Correct Answer
A. A smaller stream or river that flows into a main river
Explanation
The correct answer is: a smaller stream or river that flows into a main river
24.
Because of their sheltered waters and rich supply of nutrients, wetlands provide habitats for a few living things.
Explanation
Wetlands are actually known for their high biodiversity and provide habitats for a wide variety of living organisms. They are rich in nutrients and support a diverse range of plants, insects, birds, fish, and other animals. Therefore, the statement that wetlands provide habitats for only a few living things is incorrect.
25.
Rivers wear away landforms through deposition and build new landforms through erosion.
Explanation
This statement is false because rivers wear away landforms through erosion and build new landforms through deposition. Erosion is the process by which rivers remove sediment and rock from the land, while deposition is the process by which rivers deposit sediment and build up new landforms. Therefore, the correct answer is false.
