Answer:
where is the question
explanation:
Astronomers estimate that the runoff channels seen on Mars must be at least 3.9 billion years old. How do they estimate ages like this? a. by examining radioactive rocks from these channels returned to Earth by robot probes b. by counting impact craters in the regions containing these channels c. by looking for the erosion of these channels by the regular periods of rainfall that occur on Mars even today d. by measuring the height of the region in which the channels occur; on Mars, older regions are always lower in elevation e. guessing
Answer: b. by counting impact craters in the regions containing these channels
Explanation:
In counting the impact craters in the areas containing the runoff channels in question, scientists are able to infer the ages of these channels.
The logic is simple, the longer these areas have been exposed, the more meteors they would have been hit by to create these craters. Therefore areas with more craters must have been around for longer and using mathematical models, they come up with age estimates.

14. Weathering and erosion occur when which two Earth
system spheres interact?
a. geosphere and biosphere
b. atmosphere and hydrosphere
c. biosphere and atmosphere
d. geosphere and atmosphere
Answer:
The atmosphere, hydrosphere, and biosphere interact with the geosphere through weathering and erosion. For example, rain and plants can weather rocks into sediments. Wind and flowing water can erode rocks and sediment and deposit them in new places.
Weathering and erosion occur when the geosphere and atmosphere two Earth system spheres interact. The correct option is D.
What happens when the atmosphere interacts with the lithosphere?
Wind erosion, where air currents wear away small pieces of rock over long periods of time, is one example of how the atmosphere affects the lithosphere. This can smooth out large areas of the lithosphere over very long periods of time, resulting in flat plains of soil or worn-down rock faces.
This precipitation connects the hydrosphere to the geosphere by promoting erosion and weathering, surface processes that break down large rocks into smaller ones over time. Erosion and weathering turn large chunks of rock—even mountains—into sediments like sand or mud over time.
When bodies of water or rain cause land formations to erode, the hydrosphere interacts with the geosphere. Rivers and rainstorms break down rocks into small particles while also forming new rock patterns. The hydrosphere generates snow and ice, which harden and cool the geosphere.
Thus, the ideal selection is option D.

now that you have a better understanding of natural selection, write Alex young an argument for the claim you think is best supported about the mystery of the rough skinned newts
The mystery of ough skinned newts is associated with the fact that members of that species have been presenting much higher levels of poison than they used to be.
The ough skinned newts is a species of salamander that has toxins on its skin, which can infect predators and even humans.
The mystery of ough skinned newts can be explained with natural selection, as the natural habitat of these salamanders was invaded by very resistant snakes that are predators of ough skinned newts. The resistance of these snakes meant that the toxins in the skin of ough skinned newts were not enough to protect them. This caused the ough skinned newts to be killed more often and in greater numbers. However, the ough skinned newts who had higher levels of toxins managed to survive the attack of predators, including snakes. Those ough skinned newts that survived spawned other ough skinned newts that have the same toxin content.
Over time, the ough skinned newts with lower levels of toxins died, while those with higher levels of toxins survived and generated more ough skinned newts, which caused the species to change. This is an example of natural selection, as it allowed individuals more adapted to the environment to survive.
Natural selection is known to be the various methods used by animals in a populations of living organisms so that they can adapt and also change.
In regards to Natural selection the rough-skinned newt population is known to have some measures of change. The newt population is one that has a whole lots of variation in regards to poisonousness among animals.
This is due to the fact that they have predators (snakes), which is said to make the more poisonous traits to be adaptive in course of time.
What is the study of rough-skinned newts about?The Studies of this specie has shown that they have the ability to produce toxins. This toxin is what they use as a form of defense against a predator attack and adapt to their environment.
The common garter snake is known to be a common predator of rough-skinned newts, and has shown some measure of resistance to the toxin produce by the newt.
So therefore, newts have been found to create more potent toxin that makes that is specific for the snakes that has greater form of resistance to the toxin.

What is the difference between an ocean and a sea? What is the difference between an ocean and a sea? The term sea is used to describe the global, interconnected water body covering 70% of the Earth's surface, whereas oceans refer to the individual basins within this global sea. The term ocean is used in the Northern Hemisphere, and sea is used in the Southern Hemisphere, so the difference results from geographical location. Oceans tend to be composed primarily of salt water, while seas tend to be composed of a near even mixture of brackish and fresh water. Seas are generally smaller than an ocean and tend to be at least partly enclosed by land, such as large, inland, saline water bodies. An ocean is a vast body of water encompassing 70% of the Earth, whereas a sea refers specifically to a large, inland, saline body of water.
Answer:
an ocean is larger than a sea

What stratigies can you use to reduce your electricity bill? How much money could you save?If possible, discuss your ideas with you classmates.
Answer:
A simple thing you can do is use less electricity. For example, people use electricity for light a lot and they can reduce that by just not using it in certain times like in the day time, they can open their windows for sun light and turn the lights on in night time. People also use too much electricity on gadgets and electronics and they can reduce that by just not charging them too often and using them a bit less. By doing these methods you can maybe save around 10$ to 100$ or even more.
Hey Guys. THIS IS URGENT!
I have to create 10 TREATY to protect GBR.
PLZ help!
Answer:
The Great Barrier Reef Intergovernmental Agreement, signed by the Prime Minister and Queensland Premier, provides a framework for the Australian and Queensland governments to work together to protect the Great Barrier Reef.
The Agreement recognises that key pressures on the Reef—such as climate change impacts, catchment water quality and coastal development—cannot be effectively addressed by either government on their own.
The Agreement has been in place between successive governments for over 40 years, beginning with the Emerald Agreement in 1979. It was updated in 2009 to provide a contemporary framework for cooperation between the governments, recognising challenges such as climate change and catchment water quality that were not foreseen at the time of the 1979 Agreement. An assessment of the implementation of the Agreement is undertaken every five years.
The Agreement was updated in 2015 to reflect the shared vision for the future outlined in the Reef 2050 Plan, and renews the Australian and Queensland governments’ commitment to protecting the Great Barrier Reef World Heritage Area including its Outstanding Universal Value.
The Agreement is currently being reviewed and a revised Agreement is expected to be finalised by mid-2021.
what volcanoes tend to be smaller and can form quickly. They have a dome on top and form from moderately explosive eruptions of pyroclastic material.
Answer:
Shield Volcano
Explanation:
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels further and forms thinner flows than the more viscous lava erupted from a stratovolcano.
Which of the following volcanoes would you expect to erupt explosively : A volcano located near a subduction zone, or a volcano located on an island over a mantle hotspot? Explain your answer in terms of how the composition of the magma/lava impacts the physical properties (especially viscosity) of the magma, and how that would or would not lead to an explosive eruption. (7 points)
Answer:
The volcano over a mantle hotspot
Explanation:
I say this because lava comes from the grinding of those mantles, which melt rocks and make lava. If the mantles are super active, the lava will more than likely be explosive. Think of this (heat wise) as tea boiling in a kettle. The stove is the mantle, kettle as volcano and water as lava. When the mantles get hot enough they push that heat and pressure into the water, making it boil and when the steam starts to squeal out of the kettle, the volcano has erupted. Hope this helped!
