What is a stream’s longitudinal profile?

Longitudinal profiles are plots of the elevation vs distance from the stream mouth to the upper reaches within watershed basin. They help to establish relationship between slope steepness and distance from the upper to lower reaches. Slope or gradient can be measured in degree or percentage (rise over run).

What are volcanoes account for the distribution of volcanoes on the surface of the earth?


Around 80% of volcanic activity is found along subduction boundaries. Mid-ocean spreading centres and continental rifts account for around 15% of volcanic activity. Rest is intra-plate volcanism.

What is the called from which water flows receive water?

The stream channel is the conduit for water being carried by the stream. The stream can continually adjust its channel shape and path as the amount of water passing through the channel changes. The volume of water passing any point on a stream is called the discharge.

What is a river discharge?

‘River discharge’ is the volume of water flowing through a river channel; measured at any given point in cubic metres per second.

Which is the correct term for water that flows in a channel regardless of size?

Stream = water that flows in a channel, regardless of size. River = general term for streams that carry substantial wants of water and have numerous tributaries.

What is the longitudinal profile quizlet?

What is the longitudinal profile? The cross-sectional area from the headwaters to the mouth. How will channel velocity change along the longitudinal profile of a stream? Velocity will start low and gradually increase toward the mouth due to increasing discharge downstream.

What is meant by the term evapotranspiration quizlet?

Evapotranspiration. Evaporation from soil, plants and water bodies, together with water losses from plant leaves. Evaporation. Net loss of water from a surface resulting from a change in the state of water from liquid to vapor and the net transfer of this vapor to the atmosphere.

What is a stream profile?

Stream profile

· includes the point of origin of the stream called the head, the point of termination called the mouth, and a decreasing gradient of the stream channel towards the mouth—examples of the mouth of the stream are the juncture of the stream and: another stream; a pond or lake; the ocean.

How do you describe the distribution of a volcano?

Volcanoes occur at any location where the Earth’s crust is broken allowing the magma within the Earth to escape. Volcanoes are commonly found at edges of tectonic plates. … Near tectonic plate boundaries. The world’s tectonic plates is where you find the distribution of major earthquakes and volcanoes.

How are volcanoes distributed in the Philippines?

The patterns of Volcanoes in the Philippines follow a mostly linearly dispersed pattern. This is because the Philippines is in line with the convergent boundary of the Philippine and Pacific plates. Subduction zones around the Philippines have caused volcanoes to form just as other countries have experienced.

What is the distribution of earthquake?

Earthquakes are not randomly distributed around the earth, rather they are located in distinct zones which can be related to the margins of tectonic plates on the Earth’s surface. Figure 6 shows the distribution of areas of most frequent earthquake activity. The active plate boundaries are superimposed on this map.

What is stream deposition?

A stream’s sediment load is typically deposited, eroded, and redeposited many times in a stream channel, especially during climatic variations such as flooding. Sediments are deposited throughout the length of the stream as bars or floodplain deposits.

What is it called when groundwater enters a lake or stream and becomes surface water?

Recharge. Runoff. When precipitation reaches the earth’s surface, some of it will flow along the surface of the land and enter surface water like lakes, streams, and rivers, as runoff. The rest of it soaks or percolates into the soil, called recharge.

What are the 3 types of water movement?

The types are: 1. Saturated Flow 2. Unsaturated Flow 3. Water Vapor Movement.

What river has the fastest current in the United States?

Off the Atlantic seaboard of the United States, the Gulf Stream flows at a rate nearly 300 times faster than the typical flow of the Amazon River. The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour).

What is the deepest river in the world Wikipedia?

• location Boyoma Falls
Mouth Atlantic Ocean
Length 4,700 km (2,900 mi)
Basin size 4,014,500 km2 (1,550,000 sq mi)

Why does river discharge decrease?

Vegetation intercepts precipitation and slows the movement of water into river channels. This increases lag time. Water is also lost due to evaporation and transpiration from the vegetation. This reduces the peak discharge of a river.

What is peak discharge in a river?

The peak discharge is the time when the river reaches its highest flow. There is a delay because it takes time for the water to find its way to the river. … The normal (base) flow of the river starts to rise when run-off, ground and soil water reaches the river. This is shown on the hydrograph as the rising limb.

What is Baseflow in geography?

The base flow is the water that reaches the channel through slow throughflow and permeable rock below the water table. As storm water enters the drainage basin the discharge rates increase. … The highest flow in the channel is known as the peak discharge.

What is flood Short answer?

Overview. Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
