What changes occur in a wave as it approaches shore?

It is a process known as shoaling. When waves feel the bottom they slow down and decrease their wavelength but the period of the waves does not change. The height of the wave will steadily increase until the wave becomes unstable and breaks near the beach.

How is salt mined in Africa?

Salt in Africa is typically mined through either traditional methods, such as hand mining and evaporative techniques in salt flats, or through modern methods such as mechanized extraction using heavy equipment and drilling. In countries like Senegal, Mali, and Ethiopia, salt is often harvested from salt flats or salt pans where seawater has evaporated, leaving behind salt deposits that can be collected manually or with machinery.

What is the difference between wind speed and storm surge?

Wind speed refers to the speed at which air moves in the atmosphere, while storm surge is the abnormal rise in seawater level during a storm, caused primarily by the storm's winds pushing water toward the coast. Wind speed is measured in miles per hour or kilometers per hour, while storm surge is measured in feet or meters above normal tide levels.

How would a person enter a rainforest?

A person can enter a rainforest by finding an entrance or trail leading into the forest. It is important to follow established paths to minimize impact on the environment and ensure safety. It is also recommended to inform someone of your plans and take necessary precautions before entering a rainforest.

Where does the water come from to be absorbed by plants?

Water is absorbed by plants primarily through their root systems from the soil. This water is initially taken up by the roots from the surrounding soil and is then transported through the plant's vascular system to different parts of the plant for various physiological processes. Additionally, plants also absorb water via their leaves from the atmosphere through a process called transpiration.

What are the composition of minerals?

Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. They are composed of elements such as silicon, oxygen, aluminum, iron, magnesium, sodium, and potassium, among others. Minerals form through various geological processes and can be identified based on their physical properties, including color, hardness, luster, and cleavage.

What forces are not equal and opposite?

It appears so that, there are not two identical Objects producing force exactly identical,since they are not located at the same Location at the very same time.I call it locality effect.By accepting this as a fact,all forces are unequal.

Forces will not oppose but make Subject(even if that subject is a force producer) to perform accordingly,in all possible forms and direction.

I would say for every action there is an outcome.

Above statement is just personal suggestion and not a law.

Who is the best person to ever live on the face of this earth?

It is subjective and impossible to determine who the best person to ever live on earth is as opinions vary greatly. Different people throughout history have made significant contributions in various fields, leaving a lasting impact on society.

What state of matter are shown by minerals?

Water exists in all three states --- solid, liquid and gas. Water becomes a solid when it is frozen. The water molecules bond together when the temperature is below 0°C. Water is in its liquid state when at room temperature (0°C to 100°C). Water becomes gas when it is heated above 100°C.

How does energy enter into the living parts of an ecosystem?

Energy enters the living parts of an ecosystem through the process of photosynthesis, where plants and other photosynthetic organisms convert sunlight into chemical energy. This energy is then transferred through the food chain as organisms consume each other, with each consumer utilizing the energy for various life processes.

Describe the six main crystalline structures of silicate minerals?

Isolated tetrahedra silicates do not link with other silicon or oxygen atoms

Ring Silicates form by sharing oxygen atoms

Single Chain Silicates form a chain when sharing oxygen atoms

Double Chain Silicates form when two or more single chains of tetrahedra bond to each other

Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra

Framework Silicates form when each tetrahedron is bonded to four other tetrahedras

What is the major cause of different sea tides?

The major cause of different sea tides is the gravitational pull of the Moon and the Sun on Earth's oceans. The gravitational force from these celestial bodies creates bulges in the waters, leading to high and low tides as Earth rotates.

Why are surface waves the most destructive waves?

Surface waves travel more slowly than body waves but are mor distructive. Most of the damage during an earthquake comes from surface waves which can literally shake the ground out from under a building.

Is balanced force greater than a net force of zero?

No, a balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in a net force of zero. This means that the object will not accelerate and will remain at rest or continue moving at a constant speed.

Low area on Earth in which an ocean formed when the area filled with water from torrential rains?

A low area that fills with water during storms is called a flood plain. Rapid City, SD is the site of such a plain, and in 1972, 12 inches of rain fell in two hours, devastating the Rapid Valley.

Do sea stars eat copepods?

When studying animals it is important to know the diet and predators of each animals. Yes, the Sea stars do eat Copepods.

What is the original source of all the food energy on earth?

The original source of all food energy on Earth is the sun. Through the process of photosynthesis, plants convert sunlight into energy that is stored in the form of carbohydrates. This energy is then transferred through the food chain as animals consume plants or other animals.

What factors have proven to be consistent predictors of major earthquakes?

Some consistent predictors of major earthquakes include the movement of tectonic plates, historical seismic activity in a region, and the buildup of stress along fault lines. Monitoring changes in ground deformation, seismic activity, and changes in groundwater levels can also help predict potential earthquakes. Ultimately, the science of earthquake prediction is still evolving and there is no foolproof method to predict exactly when and where a major earthquake will occur.

Why is Florida prone to sinkholes?

Florida is prone to sinkholes because the state's underlying geology consists of limestone, which can dissolve over time due to the acidic nature of rainwater. When the limestone dissolves, it can create cavities underground that can eventually collapse, leading to sinkholes. Additionally, factors such as heavy rainfall, drought, and human activities like groundwater pumping can also contribute to sinkhole formation in Florida.

Is earth the second or third or fourth planet?

Earth is the third planet from the Sun in our solar system.

What are the four essential ingredients for life on earth?

The four essential ingredients for life on Earth are water, carbon, energy source (such as the sun), and a mix of elements like oxygen, nitrogen, hydrogen, phosphorus, and sulfur. These components are necessary for biological processes and the formation and sustenance of living organisms.

What is an example of a sudden geologic process?

An example of a sudden geologic process is a volcanic eruption. These events can release massive amounts of lava, ash, and gases in a short period, causing rapid changes to the landscape and environment.

In which layer of the sun is a huge supply of energy produced?

Energy in the form of light and heat is produced in the sun's core through nuclear fusion reactions. This energy then moves outwards through the radiative zone and convective zone before reaching the sun's surface (photosphere) and being emitted as sunlight.

What color streak does silver have?
