The texture of an igneous rock that cools very quickly when it forms is typically smooth and shiny, which is known as a glassy texture.
Hence, the correct answer is smooth and shiny.
Igneous Rock formation:Igneous rocks are formed when magma cools and solidifies. The texture of an igneous rock is determined by the rate of cooling of the magma. If the magma cools very slowly, the resulting rock will have large crystals, while rapid cooling results in a finer-grained texture.
When magma cools extremely quickly, as in the case of volcanic eruptions, it solidifies almost instantly and may form a glassy texture.
Otherwise, if the cooling rate is slower, the rock may have a crystalline texture with visible minerals, which are often arranged in an interlocking pattern. The mineral composition and texture of an igneous rock can provide clues about its origin.

(so something that lasted one-tenth of the age of the earth would be ten yards, and something that lasted one-half of the age of the earth would be fifty yards.) on this scale, how far on the football field would represent the time between the first appearance of abundant shelly creatures and today?
A little more than 1 yard on a football pitch would symbolise the period starting when the demise of the dinosaurs allowed room for the emergence of big mammals and ending today on this size. Option 1 is Correct.
An age for the Earth has been established through geological evidence based on several radiometric techniques. Every duration of time may be represented on a football pitch by a distance equal to the length of the Earth's age, which is 100 yards.
So, if something lasted a tenth of the age of the Earth, it would be 10 yards long, and if it lasted a half of the Earth's age, it would be fifty yards. Option 1 is Correct.
So, on this scale, 66 million year ≡ (66/4543) × 100 yard length

Earth’s surface is made up of a system of moving plates. The heavy black lines on the map mark the plate boundaries. The map also shows the approximate age of different parts of the ocean floor in millions of years (m.y.). Which statement is best supported by the data in the map?
The map of the Earth's surface shows that C. The parts of the ocean floor that are closer to a plate boundary tend to be younger than other parts of the ocean floor.
Why is this so ?The ocean floor is constantly being created and destroyed due to the movement of tectonic plates. At mid-ocean ridges, new oceanic crust is formed through volcanic activity and spreads outwards, away from the ridge.
As the crust moves away from the ridge, it cools and becomes denser, eventually sinking back into the mantle at subduction zones. As a result, the oceanic crust closest to a plate boundary is generally younger than the crust farther away from the boundary.

If the diameter of Earth is approximately 8000 miles, approximate the distance between A and B if angle ACB has the indicated measure. (Round your answers to the nearest mile.) A) 49 degrees B) 4 degrees
When angle ACB is 49 degrees, the approximate distance between A and B is 3420 miles. when angle ACB is 4 degrees, the approximate distance between A and B is 280 miles.
A) For angle ACB = 49 degrees:
Step 1: Convert the diameter of Earth (8000 miles) to its radius, since we'll be working with a circular geometry. The radius of Earth is half the diameter, so it's 4000 miles.
Step 2: Use the formula for finding the arc length (distance between A and B) on a circle, which is:
Arc length = Radius x Angle (in radians)
Step 3: Convert angle ACB from degrees to radians:
Radians = Degrees x (π/180)
Radians = 49 * (π/180) ≈ 0.855 radians
Step 4: Calculate the arc length (distance between A and B):
Arc length = 4000 miles x 0.855 radians ≈ 3420 miles
So, when angle ACB is 49 degrees, the approximate distance between A and B is 3420 miles.
B) For angle ACB = 4 degrees:
Step 1: We already know the radius of Earth is 4000 miles.
Step 2: Convert angle ACB from degrees to radians:
Radians = 4 x (π/180) ≈ 0.070 radians
Step 3: Calculate the arc length (distance between A and B):
Arc length = 4000 miles x 0.070 radians ≈ 280 miles
So, when the angle ACB is 4 degrees, the approximate distance between A and B is 280 miles.

A sudden movement along the boundary of a tectonic plate is an (blank)?
A sudden movement along the boundary of a tectonic plate is an earthquake.
When there is a sudden movement or shift at the boundary between two tectonic plates, it releases energy in the form of seismic waves, which we feel as an earthquake.
Earthquakes can cause a wide range of destructive effects, including ground shaking, landslides, and tsunamis. The severity of the effects depends on a variety of factors, such as the magnitude of the earthquake, the distance from the epicenter, and the geological features of the area. In areas with poorly constructed buildings and infrastructure, earthquakes can cause significant damage and loss of life. Scientists study earthquakes to better understand the behavior of tectonic plates and to develop strategies for predicting and mitigating their effects.

The population of Ghana increased by 120% from 1957 to 1998.
To find the percentage increase in the population, we need to calculate the difference in population between the two years and then divide it by the population in 1957 and multiply by 100.
First, we can calculate the difference in population:
Population in 1998 - Population in 1957 = 12,000,000
Next, we can calculate the percentage increase:
(Population in 1998 - Population in 1957) / Population in 1957 x 100
= (12,000,000 - 5,000,000) / 5,000,000 x 100

What are rock types?There are three main types of rocks: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from cooled and solidified lava or magma. They can be further classified into two subcategories based on their texture: intrusive and extrusive. Intrusive igneous rocks cool slowly beneath the Earth's surface, resulting in a coarse-grained texture, while extrusive igneous rocks cool quickly on the surface, resulting in a fine-grained texture.
Sedimentary rocks are formed by the accumulation and consolidation of mineral and organic particles, such as sand, silt, and shells, which are deposited in layers. These layers eventually become compacted and cemented together, forming sedimentary rocks. Sedimentary rocks can be further classified into three subcategories: clastic, chemical, and organic.
Metamorphic rocks are formed when existing rocks are subjected to high heat, pressure, or chemically active fluids, causing them to change their composition, texture, or structure. Metamorphic rocks can be further classified into two subcategories: foliated and non-foliated, based on their texture. Foliated metamorphic rocks have a banded or layered appearance due to the alignment of minerals, while non-foliated metamorphic rocks do not have any visible banding.
