What are the causes of turbidity in water? Turbidity is caused by particles suspended or dissolved in water that scatter light making the water appear cloudy or murky. Particulate matter can include sediment – especially clay and silt, fine organic and inorganic matter, soluble colored organic compounds, algae, and other microscopic organisms. How is turbidity […]

Is pH 11 an acid a base or neutral? A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. How […]

What was the Earth like 20000 years ago? 20,000 YEARS AGO. Last Glacial Maximum- a time, around 20,000 years ago, when much of the Earth was covered in ice. The average global temperature may have been as much as 10 degrees Celsius colder than that of today. The Earth has a long history of cycles […]

How does global warming affect animals and plants? Climate change also alters the life cycles of plants and animals. For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, […]

What are four features formed by wave erosion? Wave energy produces erosional formations such as cliffs, wave cut platforms, sea arches, and sea stacks. When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands. How do ocean waves cause erosion quizlet? The force of waves striking the shoreline breaks […]

Is heat a particle? Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat. When heat is […]

How is water related to life? Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients. […]

What phase change happens when energy is added to a solid? One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules. Does heat […]

What is between liquid and gas? gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern. Which substance can exist as solid liquid and gas? Water is the only common substance that is naturally found as a solid, liquid or […]

What is the relationship between the tilt of the earth amount of sunlight number of daylight hours and the seasons? The tilt of the Earth’s axis also defines the length of daylight. Daylight hours are shortest in each hemisphere’s winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of […]
