Biology
1 answer:
Neko [114]3 years ago
7 0

Answer:

The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.

In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer

Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate
OleMash [197]

Answer: 0.69 m/ mile.

Explanation:

The altitude gradient between two cities X and Y = \dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%

Given: Two cities are separated by 200 miles.

City X has an altitude of 122 meters.

City Y has an altitude of 260 meters.

The altitude gradient between two cities X and Y =

\dfrac{260-122}{200}=0.69\text{m/ mile}

Hence, the altitude gradient between the two cites = 0.69 m/ mile.

Select the layers of Earth that are completely solid. A. crust B. inner core C. outer core D. lower mantle E. asthenosphere
melisa1 [442]

Answer:

The correct answer would be A. crust.

The crust is the outermost layer of the earth which is composed of different types of rocks such as sedimentary, metamorphic, and igneous rocks.

It is completely solid and can be broadly classified into two types: continental crust and oceanic crust.

The thickness of the oceanic crust is about 5 km to 10 km. It is primarily composed of basalt, gabbro, and diabase.

The thickness of the continental crust is around 30 km to 50 km.  

The crust forms lithosphere along with hard and upper mantle.

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react w
sammy [17]

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
