Honors 7th Grade Fall Final Exam Review

What is a meniscus and why is it important in measuring liquids in the lab?

A meniscus is what happens when you put a liquid into a container. When you put water in a beaker or test tube, you see a curved surface. It's like a small bubble that's curved. It is important because you want the exact measurements.

Which is the thickest of Earth's layers?

Aesthenosphere

What's Newton's first law?

An object will stay in motion unless acted upon an outside force.

What is the safety symbol for glass safety?

Beaker

The motion of hot, molten rock that continually rises, cools, and sinks is:

Convection

This type of boundary occurs where two tectonic plates push together:

Convergent

Which is the thinnest of Earth's layers?

Crust

How do density and pressure change as you go from the crust to the core?

Crust to Core = Density + Pressure Increase

This type of boundary occurs where two tectonic plates move apart:

Divergent

What food is a good model that illustrates Earth's different layers?

Egg/Avocado/Peanut M&M

Whats Newtons second law?

F = ma, Force = mass x acceleration

What is the safety symbol for fire safety?

Fire crossed out

Whats Newtons third law?

For every action there is an equal and opposite reaction

What is the safety symbol for eye safety?

Goggles

What tool is used to measure the volume of a liquid?

Graduated Cylinder

An educated guess or prediction to the possible solution to a problem is a

Hypothesis

A logical explanation or conclusion of an event based on prior knowledge or observations is an:

Inference

List the layers of the Earth from the center to the surface:

Inner Core, Outer Core, Mantle, Crust.

What is the number one safety rule?

Listen to the teacher and follow directions.

A layer of hotter, softer rock that is part of the upper mantle is the:

Lithosphere

Earth's crust and the very top of the mantle together form the:

Lithosphere

Which layer of Earth is made up of tectonic plates?

Lithosphere

Which layer of Earth do convection currents occur?

Mantle

Underwater mountain ranges where tectonic plates on the ocean floor are pulled or spread apart are called:

Mid-ocean Ridges

What procedures should be followed when practicing lab safety with electricity? (name at least 3 things)

Never unplug equipment by the cord, Do not used frayed or broken materials, Dont leave Cord hanging over table.

Which fault has sides that push together and the right side goes down

Normal

What 2 types of crust do most tectonic plates have?

Oceanic and Continental

A once huge supercontinent that reached from pole to pole was:

Pangea

This states that the Earth's lithosphere is made up of huge plates that move over the surface of the Earth:

Plate Techtonic Theory

The gathering of factual information by using the senses is:

Qualitative Observations

List the general steps to the scientific process (specific number of steps may vary).

Question/Observation Research Hypothesis Experiment/Data Conclusion + Analysis Repeat

What are the important parts of a lab conclusion?

Restate hypothesis inferences for results, future questions

Which fault has sides push together then the right side goes up

Reverse

The gap where the mid-ocean ridge widens and new crust is formed or where continental crust widens and sinks is called:

Rift Valley

What tool is used to find the length of a book?

Ruler

What 3 key pieces of evidence were used to support Continental Drift?

Same species found on different continents, continents can fit back together, and temperatures and climates around the world.

What is the safety symbol for chemical safety?

Skulls with bones

List the steps in calibrating a triple beam balance so it has a zero starting point.

Slide back all the weight posies (that slide along the beams) so that the pointer is right at the zero line.

Which fault has sides that are moved horizontally

Strike and Slip

When one tectonic plate sinks under another, it is called:

Subduction

Large and small slabs of rock that make up Earth's crust are called:

Techtonic Plates

What are the steps involved in cleaning up broken glass in the lab?

Tell the teacher, don't touch it, be careful.

This type of boundary occurs where two plates scrape past each other:

Transform

What tool is used to find the mass of a wooden block?

Triple Beam Balance
