Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building

Answers

Answer:

The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.

Explanation:

The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.

The steps involved in the rock cycle are:

Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface.

After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water.

The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks.

Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.

Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). the newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

The carbon dioxide from fossil fuels acts is the same as the carbon dioxide that we breath out... Why does burning fossil fuels cause global warming if breathing doesn't?


The carbon in fossil fuels is very very old. The carbon that we breath out is much newer.
The carbon in fossil fuels was unable to reach the atmosphere until humans dug it up. The carbon we breath out was already moving around on the surface.
Plants don't like to absorb the carbon that comes from fossil fuels. However, plants love to use the carbon that we breath out.
For some reason the carbon from fossil fuels is stronger than the carbon that we breath out.

Answers

Answer:

When we breathe out CO2 There are a lot of plants to take carbon dioxide away, but due to the cutting down of forests there are fewer trees to absorb CO2 and more burning of fossil fuels is causing CO2 levels in the atmosphere to increase

PLS MARK ME AS BRAINLIEST

Explanation:

Answer:yes

Explanation:because the fossil fuel is much stronger than the carbondioxide we breath out e.g the fossil fuel that comes out of factories are much so it can easily cause global warming than that of the carbon dioxide we breath out

A habitat that receives little or no precipitation will most likely be suitable for organisms that -



spend most of the day in the sunlight.


are covered in thick fur to keep warm.


store large quantities of water internally.


hibernate for long periods of time.

Answers

Store large quantities of water internally. Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation

Your answer is C- Store large quantities of water internally

Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.

What is Precipitation?

Any liquid or frozen water that condenses in the atmosphere and falls to the ground is referred to as precipitation. Rain, sleet, and snow are only a few of its various manifestations.

Precipitation is one of the three main processes that make up the global water cycle, together with evaporation and condensation.

Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. The drips hit the ground when they are sufficiently hefty. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations.

Therefore, Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.

Answers

Answer:

They live in a forest that has trees with dark colored bark.

Explanation:

Because the dark colored moths can blend in better with dark bark than light colored moths do, they don't stand out as much, so the predators(the birds) will eat the ones that they can find easier, which happens to be the light colored moths.

What does the allele indicate in this pair of homologous chromosome?

Answers

Answer: So allele and homologue, these words are not synonymous ; but yes, alleles are always present on homologous chromosomes. One member of a homologous pair comes from father while another member comes from mother.

Explanation: An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. ... An organism which has two different alleles of the gene is called heterozygous

The terms "allele" and "homologue" are not interchangeable, it is true that alleles are always present on homologous chromosomes. A homologous pair has one parent from the mother and one from the father.

What is Homologous chromosome?

An allele is a functional DNA (deoxyribonucleic acid) coding variant that resides at a certain locus (position) on a chromosome.

Alleles are typically gene-coding sequences, however the term is occasionally used to describe non-gene sequences. Heterozygous refers to an organism with two distinct alleles of the gene.

A homologous pair of chromosomes has identical genes on each of them in the same order, although there may be differences between them that give rise to different alleles.

Therefore, The terms "allele" and "homologue" are not interchangeable, it is true that alleles are always present on homologous chromosomes. A homologous pair has one parent from the mother and one from the father.
