Answers

Answer 1

Answer:

Only early Earth was intensely bombarded by large rocks and ice from space.

Explanation:

Primitive Earth was hit several times by meteors, meteorites, rocks and ice from space. The impact of these bombings was very intense and it modified the entire structure and resources of the earth, besides harming life in general. The extinction of the dinosaurs was a result of this bombardment, for example, but there were many mass extinctions whenever one of these elements hit the planet. Another result was the modification of environmental conditions, which were very different from what we know today.

identify the explicit function for the sequence in the table. x:1, 2, 3, 4, 5, y: 8, 14, 20, 26, 32,

Answers

Answer:

The explicit function is y = 6x + 2

Explanation:

Since the change in x, Δx is constant and Δx = 1 and also, the change in y, Δy is constant and Δy = 6, we use the equation of a straight line in gradient form.

So, (y - y₁)/(x - x₁) = Δy/Δx where x₁ = 1 and y₁ = 8

So, substituting the values of the variables into the equation, we have

(y - y₁)/(x - x₁) = Δy/Δx

(y - 8)/(x - 1) = 6/1

(y - 8)/(x - 1) = 6

cross-multiplying, we have

(y - 8) = 6(x - 1)

expanding the brackets, we have

y - 8 = 6x - 6

adding 8 to both sides of the equation, we have

y - 8 + 8 = 6x - 6 + 8

y + 0 = 6x + 2

y = 6x + 2

So, the explicit function is y = 6x + 2

Answer: ;) a(n) =8 + (n-1) •6

The high temperature in the upper thermosphere: a. produces a tremendous amount of heat transfer. b. would feel cold to humans due to few molecules for heat transfer. c. is produced primarily by the increased molecular activity of argon and helium. d. is more a measure of sensible temperature than kinetic energy. e. is produced by the absorption of UV radiation.

Answers

Answer:

e. is produced by the absorption of UV radiation.

Explanation:

The thermosphere is a layer of Earth's atmosphere which is directly above the mesosphere and below the exosphere. It extends from about 85 to 500 km altitude above the earth.

In the thermosphere, the temperature is strongly dependent on the level of solar activity. When the Sun is very active and emitting more high energy radiation, the thermosphere becomes hotter by X-ray and UV radiation absorption.

Answers

Answer:

Overgrazing land for cattle farming leading to soil degradation.

Explanation:

Global Commons theory states that it is necessary for an authority to be raised as a regulatory body, to promote the protection of a global resource. These global resources are associated with environmental resources and the elements that make them up. In this case, we can consider that this theory applies to the existence of overgrazing that degrades the soil globally, since livestock is exercised throughout the world and this activity needs a regulatory body to protect the soil and its elements .

A. winter
B. summer
C. spring
D. fall

Answers

Answer:

Spring

Explanation:

The type of temperature in the area

The answer is summer. When the northern hemisphere is tilted towards the sun we are going into summer. It cannot be fall or spring because we do not have solstice days for those we have equinoxes. And it cannot be winter because the northern hemisphere would have to be pointed away for that to be the case.
