what surface features on mars today indicate that there was significant water erosion in the past?

Answers

Answer 1

Broad and shallow outflow channels curve around obstacles like craters. They seem to have been caused by unexpected floods. Valley networks mimic drainage patterns and imply long-distance water movement, indicate that there was significant water erosion on Mars.

Currently, there may be very little liquid water on the surface of Mars, just evidence of dissolved atmospheric moisture and thin coatings, which are hostile settings for any known life. The idea that water existed on Mars dates back hundreds of years before the space age. Early telescopic viewers correctly inferred that the presence of clouds and white polar caps indicated the existence of water.

Astronomer William Herschel stated in 1784 that these discoveries, along with the knowledge that Mars had a 24-hour day, likely provided its people with "a position in many respects comparable to ours." The narrative shifted to portray Mars as a "dying" planet with scant water since the existence of seas was no longer acknowledged. The dark regions, which were seen to shift periodically, were formerly believed to represent large expanses of vegetation.

How do logarithms relate to the Richter scale?

Answers

Earthquakes are measured using the Richter Scale, which is a base 10 logarithmic scale. The magnitude of an earthquake is measured by this scale, which is the amount of energy generated by it.

The magnitude increases by a factor of ten for every single rise on this scale.

In comparison to a linear scale, the logarithmic scale provides a simpler and more comprehensible manner to describe the large range of ground motion amplitude (sometimes several orders of magnitude) and energy release for distinct quakes within a tolerable range of values.

To calculate the Richter scale measure, express the amplitude in millimeters as 10 multiplied by an exponent (10x).

Hi
Can someone give me a good explanation of what happens on a constructive plate boundary and also give me an example of constructive plate boundaries

Answers

Answer:

A constructive plate boundary is when two plates move away from each other, causing molten material from the Earth’s mantle to rise up and form new crust between them. This type of boundary is responsible for the formation of new land due to the movements of the plates. An example of a constructive plate boundary is the Mid-Atlantic Ridge which is located between the North American and Eurasian plates. As these two plates move away from each other, magma from the mantle rises up and creates new oceanic crust, resulting in the formation of new land masses in the form of islands.

What is gerrymandering and why is it done ?

Answers

Gerrymandering is a tactic used to manipulate the boundaries of electoral districts to benefit a specific political party or group. It is controversial and undemocratic as it can dilute the representation and voting power of certain communities or minority groups.

The term "gerrymandering" comes from the name of Governor Elbridge Gerry of Massachusetts, who, in 1812, signed a redistricting plan that favored his party.

The reason gerrymandering is done is to give an electoral advantage to one political party or group over another. By manipulating the boundaries of districts, politicians can create districts that are heavily skewed towards their party, or that dilute the voting power of opposing parties. This can lead to a situation where one party can win a large number of seats in the legislature even if they don't have a majority of the votes.

There are two main types of gerrymandering: packing and cracking. Packing involves creating districts that are heavily populated with voters from one party, so that these voters are concentrated in a small number of districts and their voting power is reduced. Cracking involves spreading voters from one party across multiple districts, so that their voting power is diluted and they are unable to win a majority in any one district.

Gerrymandering is usually done by the party in power, when it has control of the redistricting process. This is the process of setting the boundary of the electoral districts, often done after the census, to ensure that the population of the district is relatively equal. By manipulating the boundaries, they can try to maintain or gain control of the legislature, or even the state or national government, by making it harder for the opposition parties to gain seats.

Gerrymandering is widely considered as controversial and undemocratic practice because it allows politicians to pick their voters, rather than voters picking their politicians, and can dilute the representation and voting power of certain communities or minority groups.

What does it mean to gerrymander a district ?

Answers

Gerrymandering is the practice of drawing electoral district boundaries in such a way that one political party gains an unfair advantage over its opponents (political or partisan gerrymandering) or dilutes the voting power of members of ethnic or linguistic minority groups in the United States (racial gerrymandering).

How does gerrymandering works in a district?

Redistricting occurs in each state every ten years, following the decennial census. It establishes geographic boundaries, with each district in a state being geographically contiguous and having roughly the same number of state voters.
        The resulting map has an impact on the elections of members of the United States House of Representatives and state legislative bodies in the state. Redistricting has always been regarded as a political exercise, and it is controlled in most states by state legislators and, in some cases, the governor (in some states the governor has no veto power over redistricting legislation while in some states the veto override threshold is a simple majority).

       When one party controls the state's legislative bodies and the governor's office, it has a strong incentive to gerrymander district boundaries in its favor and against its political opponents.

This is a clastic rock; all three materials were deposited at the same time. O C. This is a crystalline rock; all three materials crystallized in place at the same time. O D. This is a clastic rock with silica and calcite cement that grew in pore spaces between grains.

Answers

The correct option is D ; This is a clastic rock with silica and calcite cement that grew in pore spaces between grains.

Sandstone is a clastic sedimentary rock comprised primarily of silicate granules the size of sand (0.0625 to 2 mm). Sandstones account for 20-25% of all sedimentary rocks.

Because quartz and feldspar (both silicates) are the most resistant minerals to weathering processes at the Earth's surface, they make up the majority of sandstone.

Sandstone, like uncemented sand, can be any color due to mineral impurities, although the most prevalent hues are tan, brown, yellow, red, grey, pink, white, and black.

Because sandstone deposits frequently generate extremely visible cliffs and other geographical features, certain sandstone hues have been closely associated with specific places.

What is a logarithmic scale and why is it useful example?

Answers

A logarithmic scale displays a value increased to the power of ten. For example, the logarithm of 10 is 1 since 10 raised to the power of 1 equals 10.

Because 10 raised to the power of 2 equals 100, 100 has a logarithm of 2, and so on.

On a log scale, for example, the numerals 10, 100, 1000, and 10000 are equally spaced since their digit count increases by one each time: 2, 3, 4, and 5 digits. Adding two digits doubles the quantity measured on the log scale by a factor of 100 in this manner.

What was the main difference between the birds that Darwin studied that lived on the different Galapagos Islands?

Answers

The main difference between the birds that Darwin studied on the different Galapagos Islands was the degree of variation among the species.

Charles Darwin's visit to the Galapagos Islands in 1835, during his voyage aboard the HMS Beagle, is one of the most iconic events in the history of biology. Darwin's observations of the various species of birds on the islands sparked his interest in natural selection and ultimately led to his famous theory of evolution.

One of the main differences between the birds that Darwin observed on the various Galapagos Islands was the degree of variation among the species. The birds that lived on the different islands showed a wide range of physical differences, such as size, beak shape, and coloration. For example, Darwin noticed that the finches on the different islands had differently shaped beaks, which enabled them to eat different foods. He also noticed that the mockingbirds living on different islands had different colored feathers and sang different songs.

Darwin's observations of the birds on the Galapagos Islands led him to the conclusion that the animals had evolved over time to adapt to their particular environments. He theorized that the birds on each island had adapted to their local environment in order to survive. This process of adaptation was the result of natural selection, which is the process by which organisms with advantageous traits are more likely to survive and reproduce, while those with disadvantageous traits are more likely to die out.

Plagioclase is a mineral that belongs to the feldspar group. In Bowen's reaction, plagioclase is in a continuous series. From Bowen's reaction we can also know the process of crystal formation from plagioclase. The plagioclase crystallization process begins with plagioclase-Ca which gradually reacts with the remaining solution until it changes its composition towards plagioclase-Na. This change reaction is called the solid solution series, which means that the crystallization of plagioclase-Ca-plagioclase-Na will continue if it is in an equilibrium state. The chemical formula of plagioclase mineral is NaAlSi3O8-CaAl2Si2O8.

From the Bowens reaction, we can know the process of crystal formation from this plagioclase itself, in which the sequence of crystallization of plagioclase minerals is in a continuous series. The crystallization of plagioclase-Ca in the initial phase was gradual by reacting with the remaining solution, changing its composition from plagioclase-Na. The reaction of this change, plagioclase change is a solit-solution series which is a continuous reaction, meaning that the crystallization of plagioclase-Ca ---- plagioclase-Na (Anorthit ---- Albit ) if in equilibrium will continue continuously.
