The faster an igneous rock cools, the ____ its crystals will be.-more colorful
-more irregular
-larger
-smaller

Answers

Answer 1
Answer:

The correct answer is - smaller.

The size of the crystals of the igneous rocks is directly affected by the speed of the cooling of the magma.

If the magma cools off very quickly, than the size of the crystals of the igneous rocks will be very small, while if the magma cools off very slowly, than the size of the crystals of the igneous rocks will be bigger.

This happens because of the time of influence of other factors in the formation of the rock itself. The ones that are on the surface or close to it, cool off very quickly, so there's no time for any significant influences on the rock. The ones that are deeper into the ground, cool off much slower because it is hotter, and also in that period the temperature and the high pressure manage to heavily influence the rock, thus making it having bigger crystals.

Answer 2
Answer: Smaller. The longer time it has to cool down, the bigger it will get. In this case, since it is cooling faster, the rock will be smaller.

If 3x=-21 , then x=7

Answers

Answer:

it is -7

Explanation:

It is -7 because the answer ended up being a negative and 3×-7=-21

Answer:

3x = -21        Equation

3x/3x = - 21/3x      Divide the 3x by istself so it cancels out. and what you do to                                          .                             one side you must do to the other so  -21/3x

x = -7     Aswer to -21/3

Which of the following is the shortest interval of geologic time?an eon
a period
an era

Answers

An eon is a geologically around tens of millions of years. A period is a million year included in an eon which is also made up of several eras. Therefore my answer is a period due to it being a subset of an era which is a subset of an eon.

The answer is Period. This is the shortest interval of geologic time.

Which of these best describe a steppe?a wide expanse of desert

a grassland with few trees

a cold region with tundra

a large evergreen forest

Answers

The one which best describe a steppe is a grassland with few trees Option(b) is correct. Steppe dry land with xerophilous vegetation found for the most part in locales of outrageous temperature reach and loess soil.

What does steppe means?

The Russian name for such woods is taiga, as steppe is the Russian word for meadows; and it is advantageous to utilize these terms to portray the two zones of vegetation that put forth limited lines on human existence.

Steppes are essential fields on dry territories, which are not appropriate for the foundation of trees in sloping districts, lower regions, and marshes Steppes are exceptionally assorted and mosaic-like territories described by perpetual graminoids of Bromus.

The Western Steppe was moderately immaculate by people until the seventeenth hundred years. Prior, the region was occupied by roaming clans that involved the land as field for homegrown steers and for hunting. The primary rural settlements were created by the Romans in the western piece of the steppe along waterway valleys of the Dniester.

Therefore Option(b) is correct.

Convection currents occur when materials become heated and less dense -- they become buoyant. Buoyant materials, such as continents or hot rocks or hot water or hot air:A) Tend to float on denser material or to rise up through denser rock or water or air.
B) Tend to resist any kind of motion.
C) Tend to sink into denser materials.

Answers

Answer: Tend to float on denser materials or rise up through denser rock or water or air

Explanation: buoyant materials like the crust are known to float on denser mantle. Also hot water will necessarily rise to the top allowing cold water to travel to the bottom
