Can a nonfoliated igneous rock undergo metamorphism and be turned into a foliated igneous rock? yes no

3 0

Yes it can.

Under metamorphism,which high heat or pressure is applied to the igneous rock,the igneous rock’s chemical composition or texture will be different from that of it's parent rock and turn into a metamorphic rock.

In your case,an igneous rock would undergo metamorphism where large scale mountain building process take place such as folding and faulting,and the rock would be under very high pressure,hence turn into a foliated structure. The metamorphism is called dynamic or regional metamorphism if you want to know.

For example, an igneous rock,granite, will turn into gneiss under metamorphism in which high pressure take place.

Which statement explains something that the fossil record indicates? Earth is 4. 5 billion years old. Mammals have always existe

Charra [1.4K]

The statement "Mass extinctions have occurred several times on Earth" explains the indication of the fossil record.

<h3>Indication of Fossil fuels:</h3>

Paleontologists are fascinated by the evolution and extinction of fossil species throughout geologic history. To do so, they look at all the fossils that have been preserved in sedimentary rocks.

The fossil record is what we call it. Paleontologists have been collecting fossils from sedimentary rock layers all over the world for over two centuries.

Their goal is to figure out how species have evolved over geologic time. It can be used as a geologic timescale once the succession is established.

Then, if a specific fossil is discovered in a rock, you can determine where it belongs on the geologic timescale.

Therefore, the correct option is the third sentence.

Is relative humidity or dewpoint a better variable to examine to determine if there is sufficient moisture for thunderstorms to

skad [1K]

Answer:Relative humidity is a better

measure

Explanation:

Why? Because relative humidity measures the amount of moisture in the air compared to the current temperature of the air and what it can hold at that point. While few point merely measures the temperature of the air at which it reaches dew point and dew falls. . The basic conditions for a thunderstorm are moisture, unstable air and lift. It would be easier to read off moisture level in the air since relative humidity at 90 to 100 means it will rain more certainly than it will with dew point which may only mean that dew will fall.

The _ is continuous movement of water between earth's surface and the air

masya89 [10]

The water cycle or hydrologic cycle is the continuous movement of water between the earth's surface and the air. Water molecules move from the atmosphere (or air) to the earth's surface and back again. Water moves from the atmosphere to the earth's surface via rain, snow, sleet or hail. It moves back to the atmosphere via evaporation. The sun's energy is the catalyst for the movement of water between the atmosphere and the earth's surface.
