Why is it unlikely for stable life to develop over the first few hundred million years of Earth's history

Answers

Answer 1

Answer:

In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.

how does cold front affect fishing industries ?​

Answers

Bass react to cold fronts in very predictable ways, and cold fronts put fish in predictable locations," he says. "The fishing may get tougher, but the bass are still there.

Determine whether the sentences describe sedimentary rock, intrusive igneous rock, or both.

Answers

Answer:

left to right

Explanation:

Answer:

Sedimentary rocks: They are made of weather pieces of rocks

They are formed above earth's surface

Both: They have a diverse composition, they may contain many types of minerals.

They are solid at room temperatures.

Intrusive Igneous Rocks: They are made of molten rocks called magma.

They are formed in Earth's crust or mantle.

Explanation:

Sedimentary rocks:

first one is obvious, sedimentary rocks are made from weathering

second one is tricky, although both Sedimentary rocks and Igneous Rocks could potentially form above earth's surface, the category provided here is "Intrusive Igneous Rocks", which is formed under Earth's surface, only extrusive Igneous rocks are formed above Earth's surface.

Both:

They are both rocks not minerals so they definitely have diverse compositions.

And one of the factors of rocks is that they are solid in room temperature.

Intrusive Igneous Rocks:

Igneous rocks are made when magma cools down.

Earth's crust is the solid part and the most outer part of Earth's layer, Extrusive Igneous rocks happened to form here when magma cools down and solidifies, mantle is the second outer part of Earth, where some intrusive rocks are solidified while still in the magma.

Square ABCD and isosceles triangle BUC are drawn to create trapezoid AUCD. Square A B C D and triangle B U C are attached at side B C to create trapezoid A U C D. What is the measure of angle DCU? 45o 90o 120o 135o

Answers

Answer:

135°

Explanation:

The measure of angle DCU is 135°.

This is because angle DCU is the combination of a square and a triangle.

One of the angles of the square is 90° + 45° which is the value of one of the angles of an isosceles triangle.

= 135°

Assuming Square ABCD and isosceles triangle BUC are drawn to create trapezoid AUCD. The measure of angle DCU is 135°.

Measure of angle DCU

ΔDCB=90°

ΔCBU=90°

Hence:

ΔBCU=ΔBUC

ΔBCU=(180°-90°)/2

ΔBCU=45°

Measure of  angle DCU:

ΔDCU=ΔDCB+ΔBCU

ΔDCU=90°+45°

ΔDCU=135°

Inconclusion the measure of angle DCU is 135°.

When comparing groups of stars, which group has relatively low
luminosities and temperatures?

Answers

Answer: Red dwarfs

Explanation:

Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.

Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.

El Niño is a well- known weather phenomenon. In Ecuador and Peru, fisherman knew about the phenomena long before it was well known because their fishing would be very poor during El Niño conditions. Normally Peru and Ecuador have a remarkable fishery because there is a prominent upwelling along the coast producing planktonic blooms that feed the entire ecosystem. This upwelling is driven by surface wind conditions. From your knowledge of currents and wind conditions, which of the following happens during El Niño conditions in this area?
A) The winds change from east to west offshore flow) to onshore flow or weak winds during El Niño conditions.
B) The winds shift from prevailing southwesterlies to stagnant, doldrum conditions during El Niño.
C) The winds shift from west to east onshore flow) to offshore flow east to west) during El Niño conditions.
D) The winds shift from south to north, along the coast, to west to east, across the coast.

Answers

Answer:

A. The winds change from east to west offshore flow to onshore flow or weak winds during El Niño conditions.

Explanation:

The fisherman and other people who goes into sea predict the weather with the help of winds, When winds flow from east to west the onshore flow is weak. The fishing will be poor in these condition.
