A tsunami may form as the displaced sea water nears the land.
Flat land at the mouth of a river?
The floodplain is an area of flat land found on either side of a river that usually becomes wider as the river nears its mouth. A low watery formation of land at the mouth of a river is called a delta.
Explain how the presence of silica and water in magma increases the chances of an explosive eruption?
The higher the silica content of the magma, the more explosive the eruption. Magma enriched in silica has a higher viscosity (resistance to flow). Pressures are more likely to build up behind the thicker, high silica content magma and result in potentially more explosive eruptions.
Why does a cam shaft run at half the speed of the crankshaft?
The four strokes of a four-stroke engine are intake, compression, power and exhaust. The crankshaft controls the upward and downward motion of the pistons. The camshaft controls the opening and closing of the intake and exhaust valves. Intake stroke- the intake valve is open and the exhaust valve is closed. The piston moves downward, decreasing the pressure in the cylinder, which draws the fuel-air mixture in through the intake valve. Compression stroke- both the intake valve and the exhaust valve are closed. The piston moves upward, compressing the fuel-air mixture. When the piston nears TDC (top dead center), the fuel-air mixture is ignited by the spark plug. Power stroke- both the intake valve and the exhaust valve are closed. The explosion caused by the ignition of the fuel-air mixture (combustion) forces the piston downward. Exhaust stroke- the intake valve is closed and the exhaust valve is open. The piston moves upward, forcing the gases produced by combustion out of the cylinder through the exhaust valve. So, for each firing of a given cylinder, the intake valve opens once and the exhaust valve opens once. But, for each firing of a given cylinder, the piston must travel downward and then upward twice (in each direction.). Therefore, the crankshaft must rotate twice per given cylinder firing, while the camshaft rotates only once per given cylinder firing.
How do volcanic eruptions occur?
Heat emanating from the hot/radioactive core of our planet can cause partial melting of some components of the upper mantle and crust of Earth. Where this happens the melt slowly aggregates/pools to form magma. As magma is a fluid, it can exert pressure in all directions as compared to a solid which when compressed in one direction resists deformation. This difference allows the fluid magma to force aside overlying solid rock and make its way upwards as structures called "Dykes". The Dykes will rise to the surface and stop when the weight of the column of magma in the dyke equals the weight of and equal column of the crustal rocks (through which it is forcing itself). Thus depending on the density difference between the magma and crustal rocks, the Dyke could break through to the surface (pouring magma over the land) or stop at some position before the surface (both conditions are observable in the geological record). However, most magmas contain a lot of dissolved volatile components (gasses) and as the Dyke nears the surface (and the pressure reduces), these come out of solution and the magma foams - like opening a bottle of Champagne. The presence of the foam means that the overall density of the magma column is reduced and the magma often breaks through to the surface and beyond, allowing the magma to build a volcano (which is higher than the land around it) above the point of crustal exit. The escaping gas is therefore the main cause of a volcanic eruption and is responsible for the explosions, eruption columns and lava fountains.
What happens As a wave nears the shore its characteristics begin to change when the water depth is half of its?
When a wave nears the shore and the water depth is half of its wavelength, the wave starts to feel the seabed below. This causes the wave to slow down, shorten, and increase in height. This process is known as wave shoaling.
As a wave nears the shore its characteristics begin to change when the water depth is half of its .?
When a wave reaches water half of its wavelength, it undergoes wave refraction, causing the wave crest to become steeper and move closer together. This change in wave characteristics is due to the decrease in water depth, which causes the wave to slow down and compress as it approaches the shore.
As a wave nears the shore its characteristics begin to change when the water depth is half of its?
When the water depth is half its wavelength, waves start to interact with the seabed, causing them to slow down and increase in height. This transformation is due to the decrease in water depth, which causes the bottom of the wave to start feeling the seabed's resistance. This interaction can also lead to the wave's crest bending forward, creating a breaking wave as it approaches the shore.
What can happen when ozone nears the ground?
If ozone nears ground, it will act as a pollutant. It causes breathing problems.
Is nears an adverb or verb?
The word nears is a verb form. It is the present tense, third person singular of the verb 'to near.'

WHAT force acts on an ocean wave as it nears the shore causing it to act differently?
The force that acts on an ocean wave as it nears the shore is called shoaling. Shoaling occurs when the wave encounters shallower water, causing the wave to slow down, increase in height, and change in shape. This change in wave behavior is due to the interaction between the wave and the ocean floor.
