Why are there successive layers of frozen ice in the middle of this band? a. Cryo-volcanic activity nearby resurfaced the gap over time from multiple eruptions. b. Impacts from asteroids caused the surface to crack multiple times from shock waves propogating through the icy surface crust. c. Numerous collisions between the two ice sheets caused the surface to fracture and split in multiple locations over time. d. Bending in the fault allowed the surface to be pulled apart, which created openings that allowed warmer, softer ice from below Europa's brittle ice shell surface, or frozen water from a possible subsurface ocean, to reach the surface. This softer ice then solidified and over time, multiple layers formed the structure seen today.

Answers

Answer 1

Answer:

b. Impacts from asteroids caused the surface to crack multiple times from shock waves propagating through the icy surface crust.

Explanation:

There are various collisions that are associated with the formation of the warmer ice sheets that leads to the creation of a softer ice from below and the Europa's brittle ice shell surface. As it indicated that the Europa's ice shell is surrounded by a 25 km thick as thus ice which is solidified tend to get softer and melts over a period of time. And formations of multiple layers.Other theories of the thick ice model states that that the heat was generated by these tides that centric rings shaped forms are due to the warm ice layers.
Answer 2
Final answer:

The successive layers of icy features on Europa's surface are likely due to geological activities causing the icy crust to fracture, allowing warmer, softer ice or frozen water from the subsurface ocean to reach and solidify on the surface, forming multiple layers over time.

Explanation:

The successive layers of frozen ice in the middle of the observed band are likely due to a combination of reasons, including geological and planetary activities taking place on Europa, one of Jupiter's moons. The icy crust on Europa's surface is known to be geologically young and highly active, indicating areas of geological self-renewal.

The Galileo mission confirmed the existence of a global ocean beneath Europa's icy surface. When ice is fractured in multiple places, warmer, softer ice or frozen water from this subsurface ocean or below the brittle surface might be able to reach the surface through the cracks. This softer ice then solidifies, and over time, multiple layers of ice are formed, creating the structure we observe today.  This process involves many episodes of ice cracking, shifting, rotating, and refreezing. The thickness of the icy crust varies from a few kilometers up to 20 kilometers, which allows for such movements to take place.

Answer:

a. on flood plains soils tend to be nutrient-rich and fertile

Explanation:

A floodplain is an area of the land that is adjacent to the river or steam and that stretches the channels of the base to the enclosing valleys and the soi, usually, consist of clays and silt and sands and thus the meandering water erodes the downstream of the deposition of the silt behind the lands. It also represents the and by the fluvial terraces and in terms f the ecology they are diverse and most fertile lands ad thence the wetlands and the riparian zone are those of the soil as an intermediate supply of nutrient and thus are valuable for the agriculture.

E) It is notdenser than Saturn.

Answers

Answer:

A) It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.

Final answer:

Neptune is denser than Saturn due to its different composition, which includes a higher proportion of hydrogen compounds and rocks.

Explanation:

The correct answer is A) It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks.

Neptune is denser than Saturn because it has a greater proportion of heavier elements, such as rocks and hydrogen compounds, in its composition. Saturn, on the other hand, has a greater proportion of lighter gases, such as hydrogen and helium.

This difference in composition contributes to Neptune's greater density compared to Saturn.

The highest recorded temperature on Earth was in a ______________________

a. low-latitude, high elevation desert in Mexico.

b. tropical rain forest in Brazil.

c. high-latitude, high-elevation desert in Mongolia.

d. low-latitude, low-elevation desert in Libya

Answers

Answer:

d. low-latitude, low-elevation desert in Libya

Explanation:

From 1922 until 2012, the WMO record for the highest official temperature on Earth was 57.8 °C (136.0 °F), registered on September 13, 1922 in 'Aziziya, Libya.

The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes have high temperatures due to direct sunlight, contributing to high temperatures especially in deserts like those in North Africa.

The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes, which are near the equator, generally have high temperatures because the sun's rays hit these areas more directly. This solar intensity, coupled with the low elevation that typically traps more heat due to denser atmosphere at lower altitudes, leads to high temperatures, particularly in desert regions.

Deserts are defined by their low precipitation and because of the sparse cloud cover, there is more solar energy absorption during the day, leading to extreme temperatures. The subtropical deserts, such as those in North Africa including the Grand Erg Desert, can experience very high temperatures. At low elevations in these deserts, the lack of moisture and minimal cloud cover contribute to the recording of some of the highest temperatures on Earth.

A geostationary satellite is one that stays over one location on the Earth’s surface at all times.

(A) All must have the same approximate mass.
(B) All must center their orbit with the center of the Earth.
(C) All must must travel over the equator.
(D) All must have the same distance from the Earth
(E) All must have the same period.
(F) All must have the same speed.

Answers

I think the answer is C
Final answer:

A geostationary satellite is one with an orbital period of 24 hours, remaining over the same Earth location. To maintain this, it must orbit in the equatorial plane and at a specific radius where gravitational forces allow for a period equal to Earth's rotation.

Explanation:

The question you've asked pertains to the characteristics of geostationary satellites. These satellites are unique because they have an orbital period that matches the Earth's rotational period, hence remaining above the same point on the Earth's surface at all times which means all must have the same distance from Earth. They must satisfy specific criteria to maintain a geostationary orbit:

They must orbit in the equatorial plane, which allows them to stay in line with a fixed point on Earth.

The radius of the orbit is determined by the gravitational force and the need for the orbital period to be exactly 24 hours. The distance from Earth will vary depending on these factors, but it is consistent for all geostationary satellites.

The orbital period, or the time it takes to complete one orbit, must be equal to one Earth day, which is approximately 24 hours.

Although not inherently necessary for geostationary orbits, the satellite's speed and mass may be consistent due to the uniform orbital requirements, but these are not defining characteristics of geostationary satellites.

With these conditions met, geostationary satellites are invaluable for various applications, such as communications, weather monitoring, and broadcasting.

Desert climate associated with a rain-shadow is found ________.

a. on the windward side of mountain ranges

b. on the leeward side of mountain ranges

c. in the middle of flat plains

d. along continental coastlines

Answers

Answer:

B. On the leeward (inward) side of coastal mountain ranges

Explanation:

In contrast to the windward side of a mountain which is moist, the leeward side typically has a dry, warm climate. This is because by the time air rises up the windward side and reaches the summit, it has already stripped of the majority of its moisture.

Answer:

The answer is b): on the leeward side of mountain ranges.

Explanation:

Desert climate associated with a rain-shadow is found on the leeward side of mountain ranges. A rain shadow usually forms as a dry area of land on the side of a mountain that is protected from prevailing windflow, and associated with certain types of weather systems. The side of a mountain that is protected from prevailing windflow is known as the down-wind side or the leeward side.

Basaltic material is more common

Tens to hundreds of meters can be found on the top of cinder cones, which frequently feature a bowl-shaped crater. As opposed to spatter cones, which are made of agglomerated volcanic bombs, they are made of loose pyroclastic debris, such as cinder or scoria.

Lava flow

A lava flow is the result of geothermal energy erupting from the ground at temperatures between 700 and 1200 °C in the form of lavas or magma at the planetary crust.

Cinder cone

The silicate, feldspar, olivine, mica, quartz, and other materials make up lava. Pahoehoe lava is a smooth, continuous form of lava with a ropy, billowy, or undulating surface that contributes to its low viscosity.
