The length of arc to the nearest 10th is 26 units.
A circle is a shape produced by all points in a plane at a specific distance from the center.
Given a circle of radius (r) = 2.9, an angle of 1.8 radians intercepts an arc.
The length of the arc must be determined.
(angle measure / 2) × (circumference of circle) equals arc length
Angle = (8.9 radians) × (180 degrees / π )
We know π = 3.14
Angle = 8.9 ×180 / 3.14
= 1602 / 3.14
= 510.19°
Angle measurement is 510.19 degrees.
Circumference: 2 × π × r
= 2 × 3.14 × 2.9
= 18.212 units
Arc length = (Arc length / 360) × Circumference
= 510.19 / 360 × 18.212
= 9,290.5599 / 360
= 25.81 units
As a result, the length of the are is 25.81 units. Rounding off to nearest tenth, it will be 26 units.

The diagram shows some ocean floor features. Feature A is the edge of a continent where the water is relatively shallow. Feature B is a sharp drop in depth where the ocean basin truly begins and the continental crust ends.
Which of these statements best compares Feature A and Feature B?
Feature A is the mid-ocean ridge and Feature B is the abyss.
Feature B is the mid-ocean ridge and Feature A is the abyss.
Feature B is the continental shelf and Feature A is the continental slope.
Feature A is the continental shelf and Feature B is the continental slope.
Answer:
C) Feature B is the continental shelf and Feature A is the continental slope.
Explanation:
The continental shelf is an area of relatively shallow water, usually less than a few hundred feet deep, that surrounds land. It is narrow or nearly nonexistent in some places; in others, it extends for hundreds of miles. A continental slope is the slope between the outer edge of the continental shelf and the deep ocean floor.

Explanation:
Volcanologists obviously want to keep people safe from volcanic eruptions. However, they are typically very hesitant to evacuate people too early even though they know there may still be a chance the volcano could erupt violently. Why don't volcanologists "play it safe" and just evacuate everybody at the first signs of activity?
Answer:
for me the people will notice
Explanation:
An increase in the frequency and intensity of felt earthquakes. Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground. Subtle swelling of the ground surface.
Answer:
Because Volcanoligist don't always have the funds to evacuate constantly, also much of there funds go to learning about the signs of volcanoes and therefore planes and other supplies are low.

Chemical weathering is prominent in environments characterized by:
- Higher rainfall and temperatures.
- Lower rainfall, but higher temperatures.
- Lower rainfall & temperatures.
- Higher rainfall, but lower temperatures.
Please explain!
Chemical weathering is distinguished by lower rainfall, but better temperatures.
Generally, Chemical weathering favors higher temperatures. Reactions initiate extra quickly and regularly have better quotes at higher temperatures. for that reason, chemical weathering is likewise accelerated as temperatures upward thrust.
Chemical Weathering results from chemical reactions among minerals in rocks and outside marketers like air or water. Oxygen oxidizes minerals to alteration products while water can convert minerals to clays or dissolve minerals absolutely.
Physical weathering occurs greater regularly in cold climates, due to the fact the one-of-a-kind minerals within rocks enlarge and agree at unique charges when they're heated and cooled. Repeated heating and cooling cycles subsequently purpose rocks to fracture
