Explain how earthquakes form
Answer:
Explanation:
An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.

11 Three forces are acting upon the box shown in the diagram below.
40 N
60 N
[
29 N
Assuming there is no friction between the floor and the ground, how will these forces affect the position of the box?
A. The forces will cause the box to move to the left.
B. The forces will cause the box to move to the right.
C. The forces will cause the box to collapse to the ground.
D. The forces will be unable to move the box in any direction.
Based on the image shown and attached, assuming there is no friction between the floor and the ground, "these forces will cause the box to move to the left."
The image shows that the highest force, 60N, is on the right, pushing the load to the left.
The force on the left is 40N lower than the force on the right.
The force exerted on the object's body downward is 29N, and it is lesser than the force on the right pushing the load to the left.
Hence, in this case, it is concluded that the correct answer is option A. "The forces will cause the box to move to the left."

explain how weather and climate are also affected by geologic and geographic factors, such as mountains and ocean temperature
Answer: explanation on how geography affects the climate
Explanation:
Climate is the prevailing patterns of temperature and precipitation across a region. A region’s climate can be tropical or frigid, rainy or arid, temperate or monsoonal. Geography, or location, is one of the major determining factors in climate across the globe. Geography itself can be divided into components including distance from the equator, elevation above sea level, distance from water and topography, or the relief of the landscape.
Higher Latitudes Have Cooler Climates
Latitude is a measure of distance from the equator. Locations between the Tropic of Cancer and the Tropic of Capricorn, between 23 degrees north and 23 degrees south latitude, are considered tropical. As you move away from the equator, climates shift incrementally through subtropical, temperate, subarctic and, finally, arctic at the poles. The tilt of the Earth on its axis means that the further you get from the equator, the longer the area spends tilted away from the sun each year, and the cooler and more seasonal the climate.
Water Bodies Regulate Precipitation and Moderate Climate
Over 70 percent of the Earth’s surface is covered in water, so it makes sense that water bodies influence climate. Oceans and lakes are very good at storing the heat that is created when the sun’s energy is absorbed by the water. The water heats and adds moisture to the air above it, a process that drives the major air currents around the world. Water bodies also make the climate of adjacent land masses more moderate. They absorb extra heat during warm periods and release it during cooler periods. Warm, moist ocean air drives precipitation patterns around the world when it falls as precipitation as it is carried over cooler land masses.
Mountains Disrupt Air Flow
Mountain ranges are barriers to the smooth movement of air currents across continents. When an air mass encounters mountains, it is slowed and cooled because the air is forced up into cooler parts of the atmosphere in order to move over the obstruction. The cooled air can no longer hold as much moisture and releases it as precipitation on the mountain range. Once the air is over the mountain, it no longer has much moisture, and the leeward side of mountain ranges is drier than the windward side.
Higher Elevations Have Cooler Climates
Climates become cooler and the cold season lasts longer as elevation above sea level rises. This holds true for mountains and high-elevation plateaus, such as the steppes of Mongolia. Every 1.61 kilometers (1 mile) in elevation gain is roughly equivalent to moving 1,290 kilometers (800 miles) further from the equator. Mechanistically, higher elevations have lower air pressure, fewer atoms per unit of air to excite and, thus, cooler temperatures. Mountains frequently receive more precipitation than the surrounding lowlands, but many high-altitude plains are deserts because of their location on the leeward side of a mountain range or continental mass.
When ocean currents are redirected because they collided with a land mass, this is known as _______.
A. Continental deflection
B. Convection
C. Greenhouse Effect
D. Continental Drift

Explanation:
which type of event often occurs along transform fault boundaries?
The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.

Explanation:
Which phrases describe a plateau? Check all that apply. Low relief low elevation surface cut by streams rounded or sharp peaks steep slopes on at least one side.
The statement that describes plateau is that the plateaus are a surface that are sharp peaks with steep slopes on at least one side. So, the correct option is C.
Plateaus are a part of one of the major land forms of the Earth that are a form of rough and non-uniform surfaces formed due to formation of sedimentary rocks.
Plateaus Plateaus are formed due to the magma that is present inside the Earth which is applied through an effort to push through the surface of the Earth, but during this entire process they fail to enter and pass through the crust.Plateaus may also be made, which cause the volcanic eruptions in the Earth after the lava is busted. There are several types of plateaus that are formed in different regions due to conditions of such region. The four types of plateaus that are present on Earth's surface are Continental plateaus, Volcanic plateaus, Inter-montane plateaus and Piedmont plateaus. The continental plateaus are said to be formed to separate each continent from the other. So there are about 6 continental plateaus on Earth. Volcanic plateaus cause eruptions in the form of lava.Hence, the correct option is C that the plateaus are formed as the sharp peaks with steep slopes on at least one side of such surface.
