What causes thermal pollution in rivers?
A) automobile exhaust
B) factory smokestacks
C) solar radiation
D) nuclear power plants
Answer:
D.) nuclear power plantsExplanation:
Thermal pollution is defined as a sudden increase or decrease in temperature of a natural body of water, which may be ocean, lake, river or pond by human influence. This normally occurs when a plant or facility takes in water from a natural resource and puts it back with an altered temperature
Thermal pollution is the degradation of water quality by any process that changes the ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers.

Which one of these happens in an 11 year cycle?
Coronal Mass Ejection
Prominences
Solar Flares
Sun Spots
Answer:Solar flares
Explanation:
Answer: Solar Flares
Explanation: The Sun's magnetic field goes through a cycle, called the solar cycle or known as solar flares. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

Which of these statements best describes the connection between biodiversity and evolution?
The more biodiversity an area has, the greater the chances of new species arising.
If biodiversity is high, then more predation will take place, preventing species from evolving.
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.
Evolution depends upon low biodiversity to keep population sizes down, which increases numbers of genes.

Explanation:
Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.
Answer:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.
What are convection currents?Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.

first answer (melted rock in the interior of the earth cools after so many years, turns to solid rock. after plates into each other, mountains form due to pressure which brings the rock on the earth's surface. another way is when rocks flow out with lava, the lava cools and hardens into a rock). this is my first answer. Answer about how you think melted rock deep within Earth could change over time. Would you revise your answer now? If so, how? If not, explain why.
Melted rock within the Earth changes over time crystallization and forms igneous rocks.
What is an igneous rock?One of the three primary rock types, along with sedimentary and metamorphic rocks, is an igneous rock, also known as magmatic rock. When lava or magma cools and solidifies, igneous rock is created. The partial melting of pre-existing materials in the mantle or crust of a planet can produce the magma.
Based on their chemical makeup, igneous rocks can be categorised into four groups: felsic, intermediate, mafic, and ultramafic. Most of the crust of the earth is made up of igneous rock.
The most typical igneous plutonic rock is granite. contains essential quartz, plagioclase, and alkali feldspar; hornblende, biotite, and/or muscovite are frequently present.

It has cell walls made of cellulose,
It makes its own food,
In which of these Kingdoms should the organism be classified?
Animalia
Archaea
Fungi
Plantae
A scientist lists the characteristics of an organism which he is observing. This organism should be classified under the kingdom Plantae. Thus, the correct option is D.
What is Plantae?The living organisms on the planet are divided into five different kingdoms including Monera, Protista, Fungi, Plantae, and Animalia are classified on the basis of their characteristics such as the cell structure, mode of nutrition, mode of reproduction and the body organization.
Kingdom Plantae is a kingdom of the five kingdom classification given by R. H. Whittaker. Plants include green, brown and red algae, liverworts, mosses, ferns and the seed plants with or without the formation of flowers. They have the characteristics including multicellular organisms, covered with a cell wall made up of cellulose, are autotrophs (make their own food), contain photosynthetic pigment in plastids.
Therefore, the correct option is D.

Stephan’s mother is a mineralogist, and sometimes she brings home samples to study. Stephan observesand compares these minerals. He knows minerals form in several ways. He is especially interested in the minerals that form from volcanic activity and the kinds of crystals they form. What determines crystal size in minerals formed by lava or magma?
A. the kind of mineral that formed
B. the amount of material available
C. the rate at which the minerals cooled
D. the materials in the lava or magma
The rate at which the minerals cooled determines the crystal size in minerals formed by lava or magma. The correct option is C.
What determines crystal size in minerals?The solution is extremely saturated with some minerals, crystals form as magma cools. The crystals are quite tiny because they did not have much time to form if the magma cooled quickly. The crystals have ample time to form and become huge if the magma cools gradually.
The rate at which the minerals cooled Crystal size in minerals formed by lava or magma is primarily determined by the rate at which the minerals cooled.
When lava or magma cools slowly, it allows crystals to grow larger. Conversely, when it cools rapidly, crystals have less time to grow and thus remain smaller.
Therefore, the correct option is C.

Why do you think the food dye mixed at different rates?
Answer:
The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
