How do scientists use ice to study ancient climates

Answers

Answer 1
Counting the yearly layers can date them. The oxygen in the water molecules also holds a key to past climate. Scientists are able to use the oxygen atoms in the glacial ice as a proxy for air temperature above the glacier.
Answer 2

Answer: Ice is very important for studying ancient climates. Ice can preserve the remains of organisms such as a Wholly Mammoth, possibly for hundreds of thousands of years. The details and phenotype of the mammoth such as its fur, can provide evidence of Earth's ancient climate, and where it occurred (which is somewhere that contains ice).

In humans, B is the allele for brown eyes and b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has both the B and b alleles while the other only has B alleles. Which statement is true about the brothers?

Answers

Answer:

B is the dominate trait, and b is the recessive trait. Putting them together (Bb), would still mean that the brother would have brown eyes, since Bb means that the dominant trait is shown

bb- recessive trait (blue eyes)

Bb - dominant trait (brown eyes)

BB- dominant trait (brown eyes)

Jacque could measure the height of the rock layer.

Jacque could check if the rock layer has fossils in it.

Jacque could look at the color of the surrounding rock layers.

Jacque could chip off a chunk of rock from the rock layer and smell it.

Answers

Answer:

Check if the rock layer has fossils in it.

Explanation:

The rock layer from the inside out and the fossils will tell you how old the rock is.

Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.

What can a rock layer tell about the environment?

To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:

Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.

Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.

Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.

Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.

Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.

Sleet is precipitation made of small particles of ice. How does sleet form?

Answers

Answer:

Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:

hope this helps!

Answer:

There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.

At which point is crust neither created nor destroyed?
O island chain
O mid-ocean ridge
divergent boundary
O transform boundary

Answers

Answer:

transform boundary

Explanation:

At a transform boundary, crust is neither created nor destroyed. Therefore, option (D) is correct.

What is  transform boundary?

A transform boundary, also known as a conservative boundary or a strike-slip boundary, is a type of tectonic plate boundary where two plates slide horizontally past each other. Unlike convergent boundaries (where plates collide) or divergent boundaries (where plates move apart), transform boundaries involve plates moving alongside each other in opposite directions or in the same direction but at different speeds.

The movement occurs along a fault line, known as a transform fault. Transform boundaries are characterized by intense seismic activity, resulting in earthquakes. They can also cause the formation of prominent landforms, such as transform faults, fracture zones, and offset rivers or valleys. Examples of transform boundaries include the San Andreas Fault in California, which separates the North American and Pacific plates, and the Alpine Fault in New Zealand, separating the Pacific and Australian plates.
